See the - GNU General Public License for more details. - - Under Section 7 of GPL version 3, you are granted additional - permissions described in the GCC Runtime Library Exception, version - 3.1, as published by the Free Software Foundation. - - You should have received a copy of the GNU General Public License and - a copy of the GCC Runtime Library Exception along with this program; - see the files COPYING3 and COPYING.RUNTIME respectively. If not, see - . - ----- - -Full text of license texts referred to above follows (that they are -listed below does not necessarily imply the conditions apply to the -present binary release): - ----- - -GCC RUNTIME LIBRARY EXCEPTION - -Version 3.1, 31 March 2009 - -Copyright (C) 2009 Free Software Foundation, Inc. - -Everyone is permitted to copy and distribute verbatim copies of this -license document, but changing it is not allowed. - -This GCC Runtime Library Exception ("Exception") is an additional -permission under section 7 of the GNU General Public License, version -3 ("GPLv3"). It applies to a given file (the "Runtime Library") that -bears a notice placed by the copyright holder of the file stating that -the file is governed by GPLv3 along with this Exception. - -When you use GCC to compile a program, GCC may combine portions of -certain GCC header files and runtime libraries with the compiled -program. The purpose of this Exception is to allow compilation of -non-GPL (including proprietary) programs to use, in this way, the -header files and runtime libraries covered by this Exception. - -0. Definitions. - -A file is an "Independent Module" if it either requires the Runtime -Library for execution after a Compilation Process, or makes use of an -interface provided by the Runtime Library, but is not otherwise based -on the Runtime Library. - -"GCC" means a version of the GNU Compiler Collection, with or without -modifications, governed by version 3 (or a specified later version) of -the GNU General Public License (GPL) with the option of using any -subsequent versions published by the FSF. - -"GPL-compatible Software" is software whose conditions of propagation, -modification and use would permit combination with GCC in accord with -the license of GCC. - -"Target Code" refers to output from any compiler for a real or virtual -target processor architecture, in executable form or suitable for -input to an assembler, loader, linker and/or execution -phase. Notwithstanding that, Target Code does not include data in any -format that is used as a compiler intermediate representation, or used -for producing a compiler intermediate representation. - -The "Compilation Process" transforms code entirely represented in -non-intermediate languages designed for human-written code, and/or in -Java Virtual Machine byte code, into Target Code. Thus, for example, -use of source code generators and preprocessors need not be considered -part of the Compilation Process, since the Compilation Process can be -understood as starting with the output of the generators or -preprocessors. - -A Compilation Process is "Eligible" if it is done using GCC, alone or -with other GPL-compatible software, or if it is done without using any -work based on GCC. For example, using non-GPL-compatible Software to -optimize any GCC intermediate representations would not qualify as an -Eligible Compilation Process. - -1. Grant of Additional Permission. - -You have permission to propagate a work of Target Code formed by -combining the Runtime Library with Independent Modules, even if such -propagation would otherwise violate the terms of GPLv3, provided that -all Target Code was generated by Eligible Compilation Processes. You -may then convey such a combination under terms of your choice, -consistent with the licensing of the Independent Modules. - -2. No Weakening of GCC Copyleft. - -The availability of this Exception does not imply any general -presumption that third-party software is unaffected by the copyleft -requirements of the license of GCC. - ----- - - GNU GENERAL PUBLIC LICENSE - Version 3, 29 June 2007 - - Copyright (C) 2007 Free Software Foundation, Inc. - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The GNU General Public License is a free, copyleft license for -software and other kinds of works. - - The licenses for most software and other practical works are designed -to take away your freedom to share and change the works. By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library.

A value of - -1 can be placed for entries, causing that dimension to be - treated as `newaxis`. - itershape : tuple of ints, optional - The desired shape of the iterator. This allows ``allocate`` operands - with a dimension mapped by op_axes not corresponding to a dimension - of a different operand to get a value not equal to 1 for that - dimension. - buffersize : int, optional - When buffering is enabled, controls the size of the temporary - buffers.

The iterator implementation behind - `nditer` is also exposed by the NumPy C API. - - The Python exposure supplies two iteration interfaces, one which follows - the Python iterator protocol, and another which mirrors the C-style - do-while pattern.

If a label - appears only once, it is not summed, so ``np.einsum('i', a)`` produces a - view of ``a`` with no changes. A further example ``np.einsum('ij,jk', a, b)`` - describes traditional matrix multiplication and is equivalent to - :py:func:`np.matmul(a,b) `. Repeated subscript labels in one - operand take the diagonal. For example, ``np.einsum('ii', a)`` is equivalent - to :py:func:`np.trace(a) `. - - In *implicit mode*, the chosen subscripts are important - since the axes of the output are reordered alphabetically. This - means that ``np.einsum('ij', a)`` doesn't affect a 2D array, while - ``np.einsum('ji', a)`` takes its transpose. Additionally, - ``np.einsum('ij,jk', a, b)`` returns a matrix multiplication, while, - ``np.einsum('ij,jh', a, b)`` returns the transpose of the - multiplication since subscript 'h' precedes subscript 'i'. - - In *explicit mode* the output can be directly controlled by - specifying output subscript labels. This requires the - identifier '->' as well as the list of output subscript labels. - This feature increases the flexibility of the function since - summing can be disabled or forced when required. The call - ``np.einsum('i->', a)`` is like :py:func:`np.sum(a, axis=-1) `, - and ``np.einsum('ii->i', a)`` is like :py:func:`np.diag(a) `. - The difference is that `einsum` does not allow broadcasting by default. - Additionally ``np.einsum('ij,jh->ih', a, b)`` directly specifies the - order of the output subscript labels and therefore returns matrix - multiplication, unlike the example above in implicit mode. - - To enable and control broadcasting, use an ellipsis. Default - NumPy-style broadcasting is done by adding an ellipsis - to the left of each term, like ``np.einsum('...ii->...i', a)``. - To take the trace along the first and last axes, - you can do ``np.einsum('i...i', a)``, or to do a matrix-matrix - product with the left-most indices instead of rightmost, one can do - ``np.einsum('ij...,jk...->ik...', a, b)``. - - When there is only one operand, no axes are summed, and no output - parameter is provided, a view into the operand is returned instead - of a new array. Thus, taking the diagonal as ``np.einsum('ii->i', a)`` - produces a view (changed in version 1.10.0). - - `einsum` also provides an alternative way to provide the subscripts - and operands as ``einsum(op0, sublist0, op1, sublist1, ..., [sublistout])``. - If the output shape is not provided in this format `einsum` will be - calculated in implicit mode, otherwise it will be performed explicitly. - The examples below have corresponding `einsum` calls with the two - parameter methods. - - .. versionadded:: 1.10.0 - - Views returned from einsum are now writeable whenever the input array - is writeable. For example, ``np.einsum('ijk...->kji...', a)`` will now - have the same effect as :py:func:`np.swapaxes(a, 0, 2) ` - and ``np.einsum('ii->i', a)`` will return a writeable view of the diagonal - of a 2D array. - - Examples - -------- - >>> a = np.arange(25).reshape(5,5) - >>> b = np.arange(5) - >>> c = np.arange(6).reshape(2,3) - - Trace of a matrix: - - >>> np.einsum('ii', a) - 60 - >>> np.einsum(a, [0,0]) - 60 - >>> np.trace(a) - 60 - - Extract the diagonal (requires explicit form): - - >>> np.einsum('ii->i', a) - array([ 0, 6, 12, 18, 24]) - >>> np.einsum(a, [0,0], [0]) - array([ 0, 6, 12, 18, 24]) - >>> np.diag(a) - array([ 0, 6, 12, 18, 24]) - - Sum over an axis (requires explicit form): - - >>> np.einsum('ij->i', a) - array([ 10, 35, 60, 85, 110]) - >>> np.einsum(a, [0,1], [0]) - array([ 10, 35, 60, 85, 110]) - >>> np.sum(a, axis=1) - array([ 10, 35, 60, 85, 110]) - - For higher dimensional arrays summing a single axis can be done with ellipsis: - - >>> np.einsum('...j->...', a) - array([ 10, 35, 60, 85, 110]) - >>> np.einsum(a, [Ellipsis,1], [Ellipsis]) - array([ 10, 35, 60, 85, 110]) - - Compute a matrix transpose, or reorder any number of axes: - - >>> np.einsum('ji', c) - array([[0, 3], - [1, 4], - [2, 5]]) - >>> np.einsum('ij->ji', c) - array([[0, 3], - [1, 4], - [2, 5]]) - >>> np.einsum(c, [1,0]) - array([[0, 3], - [1, 4], - [2, 5]]) - >>> np.transpose(c) - array([[0, 3], - [1, 4], - [2, 5]]) - - Vector inner products: - - >>> np.einsum('i,i', b, b) - 30 - >>> np.einsum(b, [0], b, [0]) - 30 - >>> np.inner(b,b) - 30 - - Matrix vector multiplication: - - >>> np.einsum('ij,j', a, b) - array([ 30, 80, 130, 180, 230]) - >>> np.einsum(a, [0,1], b, [1]) - array([ 30, 80, 130, 180, 230]) - >>> np.dot(a, b) - array([ 30, 80, 130, 180, 230]) - >>> np.einsum('...j,j', a, b) - array([ 30, 80, 130, 180, 230]) - - Broadcasting and scalar multiplication: - - >>> np.einsum('..., ...', 3, c) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - >>> np.einsum(',ij', 3, c) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - >>> np.einsum(3, [Ellipsis], c, [Ellipsis]) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - >>> np.multiply(3, c) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - - Vector outer product: - - >>> np.einsum('i,j', np.arange(2)+1, b) - array([[0, 1, 2, 3, 4], - [0, 2, 4, 6, 8]]) - >>> np.einsum(np.arange(2)+1, [0], b, [1]) - array([[0, 1, 2, 3, 4], - [0, 2, 4, 6, 8]]) - >>> np.outer(np.arange(2)+1, b) - array([[0, 1, 2, 3, 4], - [0, 2, 4, 6, 8]]) - - Tensor contraction: - - >>> a = np.arange(60.).reshape(3,4,5) - >>> b = np.arange(24.).reshape(4,3,2) - >>> np.einsum('ijk,jil->kl', a, b) - array([[ 4400., 4730.], - [ 4532., 4874.], - [ 4664., 5018.], - [ 4796., 5162.], - [ 4928., 5306.]]) - >>> np.einsum(a, [0,1,2], b, [1,0,3], [2,3]) - array([[ 4400., 4730.], - [ 4532., 4874.], - [ 4664., 5018.], - [ 4796., 5162.], - [ 4928., 5306.]]) - >>> np.tensordot(a,b, axes=([1,0],[0,1])) - array([[ 4400., 4730.], - [ 4532., 4874.], - [ 4664., 5018.], - [ 4796., 5162.], - [ 4928., 5306.]]) - - Writeable returned arrays (since version 1.10.0): - - >>> a = np.zeros((3, 3)) - >>> np.einsum('ii->i', a)[:] = 1 - >>> a - array([[ 1., 0., 0.], - [ 0., 1., 0.], - [ 0., 0., 1.]]) - - Example of ellipsis use: - - >>> a = np.arange(6).reshape((3,2)) - >>> b = np.arange(12).reshape((4,3)) - >>> np.einsum('ki,jk->ij', a, b) - array([[10, 28, 46, 64], - [13, 40, 67, 94]]) - >>> np.einsum('ki,...k->i...', a, b) - array([[10, 28, 46, 64], - [13, 40, 67, 94]]) - >>> np.einsum('k...,jk', a, b) - array([[10, 28, 46, 64], - [13, 40, 67, 94]]) - - """) - - -############################################################################## -# -# Documentation for ndarray attributes and methods -# -############################################################################## - - -############################################################################## -# -# ndarray object -# -############################################################################## - - -add_newdoc('numpy.core.multiarray', 'ndarray', - """ - ndarray(shape, dtype=float, buffer=None, offset=0, - strides=None, order=None) - - An array object represents a multidimensional, homogeneous array - of fixed-size items.

""" - einsum(subscripts, *operands, out=None, dtype=None, order='K', - casting='safe', optimize=False) - - Evaluates the Einstein summation convention on the operands. - - Using the Einstein summation convention, many common multi-dimensional, - linear algebraic array operations can be represented in a simple fashion. - In *implicit* mode `einsum` computes these values. - - In *explicit* mode, `einsum` provides further flexibility to compute - other array operations that might not be considered classical Einstein - summation operations, by disabling, or forcing summation over specified - subscript labels. - - See the notes and examples for clarification. - - Parameters - ---------- - subscripts : str - Specifies the subscripts for summation as comma separated list of - subscript labels. An implicit (classical Einstein summation) - calculation is performed unless the explicit indicator '->' is - included as well as subscript labels of the precise output form. - operands : list of array_like - These are the arrays for the operation. - out : ndarray, optional - If provided, the calculation is done into this array. - dtype : {data-type, None}, optional - If provided, forces the calculation to use the data type specified. - Note that you may have to also give a more liberal `casting` - parameter to allow the conversions. Default is None. - order : {'C', 'F', 'A', 'K'}, optional - Controls the memory layout of the output. 'C' means it should - be C contiguous. 'F' means it should be Fortran contiguous, - 'A' means it should be 'F' if the inputs are all 'F', 'C' otherwise. - 'K' means it should be as close to the layout as the inputs as - is possible, including arbitrarily permuted axes. - Default is 'K'. - casting : {'no', 'equiv', 'safe', 'same_kind', 'unsafe'}, optional - Controls what kind of data casting may occur. Setting this to - 'unsafe' is not recommended, as it can adversely affect accumulations. - - * 'no' means the data types should not be cast at all. - * 'equiv' means only byte-order changes are allowed. - * 'safe' means only casts which can preserve values are allowed. - * 'same_kind' means only safe casts or casts within a kind, - like float64 to float32, are allowed. - * 'unsafe' means any data conversions may be done. - - Default is 'safe'. - optimize : {False, True, 'greedy', 'optimal'}, optional - Controls if intermediate optimization should occur. No optimization - will occur if False and True will default to the 'greedy' algorithm. - Also accepts an explicit contraction list from the ``np.einsum_path`` - function. See ``np.einsum_path`` for more details. Defaults to False. - - Returns - ------- - output : ndarray - The calculation based on the Einstein summation convention. - - See Also - -------- - einsum_path, dot, inner, outer, tensordot, linalg.multi_dot - - Notes - ----- - .. versionadded:: 1.6.0 - - The Einstein summation convention can be used to compute - many multi-dimensional, linear algebraic array operations. `einsum` - provides a succinct way of representing these. - - A non-exhaustive list of these operations, - which can be computed by `einsum`, is shown below along with examples: - - * Trace of an array, :py:func:`numpy.trace`. - * Return a diagonal, :py:func:`numpy.diag`. - * Array axis summations, :py:func:`numpy.sum`. - * Transpositions and permutations, :py:func:`numpy.transpose`. - * Matrix multiplication and dot product, :py:func:`numpy.matmul` :py:func:`numpy.dot`. - * Vector inner and outer products, :py:func:`numpy.inner` :py:func:`numpy.outer`. - * Broadcasting, element-wise and scalar multiplication, :py:func:`numpy.multiply`. - * Tensor contractions, :py:func:`numpy.tensordot`. - * Chained array operations, in efficient calculation order, :py:func:`numpy.einsum_path`. - - The subscripts string is a comma-separated list of subscript labels, - where each label refers to a dimension of the corresponding operand. - Whenever a label is repeated it is summed, so ``np.einsum('i,i', a, b)`` - is equivalent to :py:func:`np.inner(a,b) `. If a label - appears only once, it is not summed, so ``np.einsum('i', a)`` produces a - view of ``a`` with no changes. A further example ``np.einsum('ij,jk', a, b)`` - describes traditional matrix multiplication and is equivalent to - :py:func:`np.matmul(a,b) `. Repeated subscript labels in one - operand take the diagonal. For example, ``np.einsum('ii', a)`` is equivalent - to :py:func:`np.trace(a) `. - - In *implicit mode*, the chosen subscripts are important - since the axes of the output are reordered alphabetically. This - means that ``np.einsum('ij', a)`` doesn't affect a 2D array, while - ``np.einsum('ji', a)`` takes its transpose. Additionally, - ``np.einsum('ij,jk', a, b)`` returns a matrix multiplication, while, - ``np.einsum('ij,jh', a, b)`` returns the transpose of the - multiplication since subscript 'h' precedes subscript 'i'. - - In *explicit mode* the output can be directly controlled by - specifying output subscript labels. This requires the - identifier '->' as well as the list of output subscript labels. - This feature increases the flexibility of the function since - summing can be disabled or forced when required. The call - ``np.einsum('i->', a)`` is like :py:func:`np.sum(a, axis=-1) `, - and ``np.einsum('ii->i', a)`` is like :py:func:`np.diag(a) `. - The difference is that `einsum` does not allow broadcasting by default. - Additionally ``np.einsum('ij,jh->ih', a, b)`` directly specifies the - order of the output subscript labels and therefore returns matrix - multiplication, unlike the example above in implicit mode. - - To enable and control broadcasting, use an ellipsis. Default - NumPy-style broadcasting is done by adding an ellipsis - to the left of each term, like ``np.einsum('...ii->...i', a)``. - To take the trace along the first and last axes, - you can do ``np.einsum('i...i', a)``, or to do a matrix-matrix - product with the left-most indices instead of rightmost, one can do - ``np.einsum('ij...,jk...->ik...', a, b)``. - - When there is only one operand, no axes are summed, and no output - parameter is provided, a view into the operand is returned instead - of a new array. Thus, taking the diagonal as ``np.einsum('ii->i', a)`` - produces a view (changed in version 1.10.0). - - `einsum` also provides an alternative way to provide the subscripts - and operands as ``einsum(op0, sublist0, op1, sublist1, ..., [sublistout])``. - If the output shape is not provided in this format `einsum` will be - calculated in implicit mode, otherwise it will be performed explicitly. - The examples below have corresponding `einsum` calls with the two - parameter methods. - - .. versionadded:: 1.10.0 - - Views returned from einsum are now writeable whenever the input array - is writeable. For example, ``np.einsum('ijk...->kji...', a)`` will now - have the same effect as :py:func:`np.swapaxes(a, 0, 2) ` - and ``np.einsum('ii->i', a)`` will return a writeable view of the diagonal - of a 2D array. - - .. versionadded:: 1.12.0 - - Added the ``optimize`` argument which will optimize the contraction order - of an einsum expression. For a contraction with three or more operands this - can greatly increase the computational efficiency at the cost of a larger - memory footprint during computation. - - Typically a 'greedy' algorithm is applied which empirical tests have shown - returns the optimal path in the majority of cases. In some cases 'optimal' - will return the superlative path through a more expensive, exhaustive search. - For iterative calculations it may be advisable to calculate the optimal path - once and reuse that path by supplying it as an argument. An example is given - below. - - See :py:func:`numpy.einsum_path` for more details. - - Examples - -------- - >>> a = np.arange(25).reshape(5,5) - >>> b = np.arange(5) - >>> c = np.arange(6).reshape(2,3) - - Trace of a matrix: - - >>> np.einsum('ii', a) - 60 - >>> np.einsum(a, [0,0]) - 60 - >>> np.trace(a) - 60 - - Extract the diagonal (requires explicit form): - - >>> np.einsum('ii->i', a) - array([ 0, 6, 12, 18, 24]) - >>> np.einsum(a, [0,0], [0]) - array([ 0, 6, 12, 18, 24]) - >>> np.diag(a) - array([ 0, 6, 12, 18, 24]) - - Sum over an axis (requires explicit form): - - >>> np.einsum('ij->i', a) - array([ 10, 35, 60, 85, 110]) - >>> np.einsum(a, [0,1], [0]) - array([ 10, 35, 60, 85, 110]) - >>> np.sum(a, axis=1) - array([ 10, 35, 60, 85, 110]) - - For higher dimensional arrays summing a single axis can be done with ellipsis: - - >>> np.einsum('...j->...', a) - array([ 10, 35, 60, 85, 110]) - >>> np.einsum(a, [Ellipsis,1], [Ellipsis]) - array([ 10, 35, 60, 85, 110]) - - Compute a matrix transpose, or reorder any number of axes: - - >>> np.einsum('ji', c) - array([[0, 3], - [1, 4], - [2, 5]]) - >>> np.einsum('ij->ji', c) - array([[0, 3], - [1, 4], - [2, 5]]) - >>> np.einsum(c, [1,0]) - array([[0, 3], - [1, 4], - [2, 5]]) - >>> np.transpose(c) - array([[0, 3], - [1, 4], - [2, 5]]) - - Vector inner products: - - >>> np.einsum('i,i', b, b) - 30 - >>> np.einsum(b, [0], b, [0]) - 30 - >>> np.inner(b,b) - 30 - - Matrix vector multiplication: - - >>> np.einsum('ij,j', a, b) - array([ 30, 80, 130, 180, 230]) - >>> np.einsum(a, [0,1], b, [1]) - array([ 30, 80, 130, 180, 230]) - >>> np.dot(a, b) - array([ 30, 80, 130, 180, 230]) - >>> np.einsum('...j,j', a, b) - array([ 30, 80, 130, 180, 230]) - - Broadcasting and scalar multiplication: - - >>> np.einsum('..., ...', 3, c) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - >>> np.einsum(',ij', 3, c) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - >>> np.einsum(3, [Ellipsis], c, [Ellipsis]) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - >>> np.multiply(3, c) - array([[ 0, 3, 6], - [ 9, 12, 15]]) - - Vector outer product: - - >>> np.einsum('i,j', np.arange(2)+1, b) - array([[0, 1, 2, 3, 4], - [0, 2, 4, 6, 8]]) - >>> np.einsum(np.arange(2)+1, [0], b, [1]) - array([[0, 1, 2, 3, 4], - [0, 2, 4, 6, 8]]) - >>> np.outer(np.arange(2)+1, b) - array([[0, 1, 2, 3, 4], - [0, 2, 4, 6, 8]]) - - Tensor contraction: - - >>> a = np.arange(60.).reshape(3,4,5) - >>> b = np.arange(24.).reshape(4,3,2) - >>> np.einsum('ijk,jil->kl', a, b) - array([[4400., 4730.], - [4532., 4874.], - [4664., 5018.], - [4796., 5162.], - [4928., 5306.]]) - >>> np.einsum(a, [0,1,2], b, [1,0,3], [2,3]) - array([[4400., 4730.], - [4532., 4874.], - [4664., 5018.], - [4796., 5162.], - [4928., 5306.]]) - >>> np.tensordot(a,b, axes=([1,0],[0,1])) - array([[4400., 4730.], - [4532., 4874.], - [4664., 5018.], - [4796., 5162.], - [4928., 5306.]]) - - Writeable returned arrays (since version 1.10.0): - - >>> a = np.zeros((3, 3)) - >>> np.einsum('ii->i', a)[:] = 1 - >>> a - array([[1., 0., 0.], - [0., 1., 0.], - [0., 0., 1.]]) - - Example of ellipsis use: - - >>> a = np.arange(6).reshape((3,2)) - >>> b = np.arange(12).reshape((4,3)) - >>> np.einsum('ki,jk->ij', a, b) - array([[10, 28, 46, 64], - [13, 40, 67, 94]]) - >>> np.einsum('ki,...k->i...', a, b) - array([[10, 28, 46, 64], - [13, 40, 67, 94]]) - >>> np.einsum('k...,jk', a, b) - array([[10, 28, 46, 64], - [13, 40, 67, 94]]) - - Chained array operations.

- -NumPy numerical types are instances of ``dtype`` (data-type) objects, each -having unique characteristics. Once you have imported NumPy using - - :: - - >>> import numpy as np - -the dtypes are available as ``np.bool_``, ``np.float32``, etc. - -Advanced types, not listed in the table above, are explored in -section :ref:`structured_arrays`. - -There are 5 basic numerical types representing booleans (bool), integers (int), -unsigned integers (uint) floating point (float) and complex. Those with numbers -in their name indicate the bitsize of the type (i.e. how many bits are needed -to represent a single value in memory). Some types, such as ``int`` and -``intp``, have differing bitsizes, dependent on the platforms (e.g. 32-bit -vs. 64-bit machines). This should be taken into account when interfacing -with low-level code (such as C or Fortran) where the raw memory is addressed. - -Data-types can be used as functions to convert python numbers to array scalars -(see the array scalar section for an explanation), python sequences of numbers -to arrays of that type, or as arguments to the dtype keyword that many numpy -functions or methods accept. Some examples:: - - >>> import numpy as np - >>> x = np.float32(1.0) - >>> x - 1.0 - >>> y = np.int_([1,2,4]) - >>> y - array([1, 2, 4]) - >>> z = np.arange(3, dtype=np.uint8) - >>> z - array([0, 1, 2], dtype=uint8) - -Array types can also be referred to by character codes, mostly to retain -backward compatibility with older packages such as Numeric. Some -documentation may still refer to these, for example:: - - >>> np.array([1, 2, 3], dtype='f') - array([ 1., 2., 3.], dtype=float32) - -We recommend using dtype objects instead. - -To convert the type of an array, use the .astype() method (preferred) or -the type itself as a function. For example: :: - - >>> z.astype(float) #doctest: +NORMALIZE_WHITESPACE - array([ 0., 1., 2.]) - >>> np.int8(z) - array([0, 1, 2], dtype=int8) - -Note that, above, we use the *Python* float object as a dtype. NumPy knows -that ``int`` refers to ``np.int_``, ``bool`` means ``np.bool_``, -that ``float`` is ``np.float_`` and ``complex`` is ``np.complex_``. -The other data-types do not have Python equivalents. - -To determine the type of an array, look at the dtype attribute:: - - >>> z.dtype - dtype('uint8') - -dtype objects also contain information about the type, such as its bit-width -and its byte-order. The data type can also be used indirectly to query -properties of the type, such as whether it is an integer:: - - >>> d = np.dtype(int) - >>> d - dtype('int32') - - >>> np.issubdtype(d, np.integer) - True - - >>> np.issubdtype(d, np.floating) - False - - -Array Scalars -============= - -NumPy generally returns elements of arrays as array scalars (a scalar -with an associated dtype). Array scalars differ from Python scalars, but -for the most part they can be used interchangeably (the primary -exception is for versions of Python older than v2.x, where integer array -scalars cannot act as indices for lists and tuples). There are some -exceptions, such as when code requires very specific attributes of a scalar -or when it checks specifically whether a value is a Python scalar. Generally, -problems are easily fixed by explicitly converting array scalars -to Python scalars, using the corresponding Python type function -(e.g., ``int``, ``float``, ``complex``, ``str``, ``unicode``). - -The primary advantage of using array scalars is that -they preserve the array type (Python may not have a matching scalar type -available, e.g. ``int16``). Therefore, the use of array scalars ensures -identical behaviour between arrays and scalars, irrespective of whether the -value is inside an array or not. NumPy scalars also have many of the same -methods arrays do. - -Overflow Errors -=============== - -The fixed size of NumPy numeric types may cause overflow errors when a value -requires more memory than available in the data type. For example, -`numpy.power` evaluates ``100 * 10 ** 8`` correctly for 64-bit integers, -but gives 1874919424 (incorrect) for a 32-bit integer. - - >>> np.power(100, 8, dtype=np.int64) - 10000000000000000 - >>> np.power(100, 8, dtype=np.int32) - 1874919424 - -The behaviour of NumPy and Python integer types differs significantly for -integer overflows and may confuse users expecting NumPy integers to behave -similar to Python's ``int``. Unlike NumPy, the size of Python's ``int`` is -flexible. This means Python integers may expand to accommodate any integer and -will not overflow. - -NumPy provides `numpy.iinfo` and `numpy.finfo` to verify the -minimum or maximum values of NumPy integer and floating point values -respectively :: - - >>> np.iinfo(int) # Bounds of the default integer on this system. - iinfo(min=-9223372036854775808, max=9223372036854775807, dtype=int64) - >>> np.iinfo(np.int32) # Bounds of a 32-bit integer - iinfo(min=-2147483648, max=2147483647, dtype=int32) - >>> np.iinfo(np.int64) # Bounds of a 64-bit integer - iinfo(min=-9223372036854775808, max=9223372036854775807, dtype=int64) - -If 64-bit integers are still too small the result may be cast to a -floating point number. Floating point numbers offer a larger, but inexact, -range of possible values. - - >>> np.power(100, 100, dtype=np.int64) # Incorrect even with 64-bit int - 0 - >>> np.power(100, 100, dtype=np.float64) - 1e+200 - -Extended Precision -================== - -Python's floating-point numbers are usually 64-bit floating-point numbers, -nearly equivalent to ``np.float64``. In some unusual situations it may be -useful to use floating-point numbers with more precision. Whether this -is possible in numpy depends on the hardware and on the development -environment: specifically, x86 machines provide hardware floating-point -with 80-bit precision, and while most C compilers provide this as their -``long double`` type, MSVC (standard for Windows builds) makes -``long double`` identical to ``double`` (64 bits). NumPy makes the -compiler's ``long double`` available as ``np.longdouble`` (and -``np.clongdouble`` for the complex numbers). You can find out what your -numpy provides with ``np.finfo(np.longdouble)``. - -NumPy does not provide a dtype with more precision than C's -``long double``\\; in particular, the 128-bit IEEE quad precision -data type (FORTRAN's ``REAL*16``\\) is not available. - -For efficient memory alignment, ``np.longdouble`` is usually stored -padded with zero bits, either to 96 or 128 bits. Which is more efficient -depends on hardware and development environment; typically on 32-bit -systems they are padded to 96 bits, while on 64-bit systems they are -typically padded to 128 bits. ``np.longdouble`` is padded to the system -default; ``np.float96`` and ``np.float128`` are provided for users who -want specific padding. In spite of the names, ``np.float96`` and -``np.float128`` provide only as much precision as ``np.longdouble``, -that is, 80 bits on most x86 machines and 64 bits in standard -Windows builds. - -Be warned that even if ``np.longdouble`` offers more precision than -python ``float``, it is easy to lose that extra precision, since -python often forces values to pass through ``float``. For example, -the ``%`` formatting operator requires its arguments to be converted -to standard python types, and it is therefore impossible to preserve -extended precision even if many decimal places are requested. It can -be useful to test your code with the value -``1 + np.finfo(np.longdouble).eps``. - -""" -from __future__ import division, absolute_import, print_function diff --git a/venv/lib/python3.7/site-packages/numpy/doc/broadcasting.py b/venv/lib/python3.7/site-packages/numpy/doc/broadcasting.py deleted file mode 100644 index cb548a0..0000000 --- a/venv/lib/python3.7/site-packages/numpy/doc/broadcasting.py +++ /dev/null @@ -1,181 +0,0 @@ -""" -======================== -Broadcasting over arrays -======================== - -.. note:: - See `this article - `_ - for illustrations of broadcasting concepts. - - -The term broadcasting describes how numpy treats arrays with different -shapes during arithmetic operations.

There are, however, cases where -broadcasting is a bad idea because it leads to inefficient use of memory -that slows computation. - -NumPy operations are usually done on pairs of arrays on an -element-by-element basis.

The simplest broadcasting example occurs -when an array and a scalar value are combined in an operation: - ->>> a = np.array([1.0, 2.0, 3.0]) ->>> b = 2.0 ->>> a * b -array([ 2., 4., 6.]) - -The result is equivalent to the previous example where ``b`` was an array. -We can think of the scalar ``b`` being *stretched* during the arithmetic -operation into an array with the same shape as ``a``.

The most -obvious examples are lists and tuples. See the documentation for array() for -details for its use. Some objects may support the array-protocol and allow -conversion to arrays this way.

The default dtype is float64. :: - - >>> np.zeros((2, 3)) - array([[ 0., 0., 0.], [ 0., 0., 0.]]) - -ones(shape) will create an array filled with 1 values. It is identical to -zeros in all other respects. - -arange() will create arrays with regularly incrementing values. Check the -docstring for complete information on the various ways it can be used. A few -examples will be given here: :: - - >>> np.arange(10) - array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]) - >>> np.arange(2, 10, dtype=float) - array([ 2., 3., 4., 5., 6., 7., 8., 9.]) - >>> np.arange(2, 3, 0.1) - array([ 2. , 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9]) - -Note that there are some subtleties regarding the last usage that the user -should be aware of that are described in the arange docstring. - -linspace() will create arrays with a specified number of elements, and -spaced equally between the specified beginning and end values. For -example: :: - - >>> np.linspace(1., 4., 6) - array([ 1. , 1.6, 2.2, 2.8, 3.4, 4. ]) - -The advantage of this creation function is that one can guarantee the -number of elements and the starting and end point, which arange() -generally will not do for arbitrary start, stop, and step values. - -indices() will create a set of arrays (stacked as a one-higher dimensioned -array), one per dimension with each representing variation in that dimension. -An example illustrates much better than a verbal description: :: - - >>> np.indices((3,3)) - array([[[0, 0, 0], [1, 1, 1], [2, 2, 2]], [[0, 1, 2], [0, 1, 2], [0, 1, 2]]]) - -This is particularly useful for evaluating functions of multiple dimensions on -a regular grid. - -Reading Arrays From Disk -======================== - -This is presumably the most common case of large array creation. The details, -of course, depend greatly on the format of data on disk and so this section -can only give general pointers on how to handle various formats. - -Standard Binary Formats ------------------------ - -Various fields have standard formats for array data. The following lists the -ones with known python libraries to read them and return numpy arrays (there -may be others for which it is possible to read and convert to numpy arrays so -check the last section as well) -:: - - HDF5: h5py - FITS: Astropy - -Examples of formats that cannot be read directly but for which it is not hard to -convert are those formats supported by libraries like PIL (able to read and -write many image formats such as jpg, png, etc). - -Common ASCII Formats ------------------------- - -Comma Separated Value files (CSV) are widely used (and an export and import -option for programs like Excel). There are a number of ways of reading these -files in Python. There are CSV functions in Python and functions in pylab -(part of matplotlib). - -More generic ascii files can be read using the io package in scipy. - -Custom Binary Formats ---------------------- - -There are a variety of approaches one can use.

If a good C or C++ library exists that -read the data, one can wrap that library with a variety of techniques though -that certainly is much more work and requires significantly more advanced -knowledge to interface with C or C++. - -Use of Special Libraries ------------------------- - -There are libraries that can be used to generate arrays for special purposes -and it isn't possible to enumerate all of them.

An instance is therefore - a specific realisation of a class. - - iterable - A sequence that allows "walking" (iterating) over items, typically - using a loop such as:: - - >>> x = [1, 2, 3] - >>> [item**2 for item in x] - [1, 4, 9] - - It is often used in combination with ``enumerate``:: - >>> keys = ['a','b','c'] - >>> for n, k in enumerate(keys): - ... print("Key %d: %s" % (n, k)) - ... - Key 0: a - Key 1: b - Key 2: c - - itemsize - The size of the dtype element in bytes. - - list - A Python container that can hold any number of objects or items. - The items do not have to be of the same type, and can even be - lists themselves:: - - >>> x = [2, 2.0, "two", [2, 2.0]] - - The list `x` contains 4 items, each which can be accessed individually:: - - >>> x[2] # the string 'two' - 'two' - - >>> x[3] # a list, containing an integer 2 and a float 2.0 - [2, 2.0] - - It is also possible to select more than one item at a time, - using *slicing*:: - - >>> x[0:2] # or, equivalently, x[:2] - [2, 2.0] - - In code, arrays are often conveniently expressed as nested lists:: - - - >>> np.array([[1, 2], [3, 4]]) - array([[1, 2], - [3, 4]]) - - For more information, read the section on lists in the `Python - tutorial `_. For a mapping - type (key-value), see *dictionary*. - - little-endian - When storing a multi-byte value in memory as a sequence of bytes, the - sequence addresses/sends/stores the least significant byte first (lowest - address) and the most significant byte last (highest address). Common in - x86 processors. - - mask - A boolean array, used to select only certain elements for an operation:: - - >>> x = np.arange(5) - >>> x - array([0, 1, 2, 3, 4]) - - >>> mask = (x > 2) - >>> mask - array([False, False, False, True, True]) - - >>> x[mask] = -1 - >>> x - array([ 0, 1, 2, -1, -1]) - - masked array - Array that suppressed values indicated by a mask:: - - >>> x = np.ma.masked_array([np.nan, 2, np.nan], [True, False, True]) - >>> x - masked_array(data = [-- 2.0 --], - mask = [ True False True], - fill_value = 1e+20) - - >>> x + [1, 2, 3] - masked_array(data = [-- 4.0 --], - mask = [ True False True], - fill_value = 1e+20) - - - Masked arrays are often used when operating on arrays containing - missing or invalid entries. - - matrix - A 2-dimensional ndarray that preserves its two-dimensional nature - throughout operations. It has certain special operations, such as ``*`` - (matrix multiplication) and ``**`` (matrix power), defined:: - - >>> x = np.mat([[1, 2], [3, 4]]) - >>> x - matrix([[1, 2], - [3, 4]]) - - >>> x**2 - matrix([[ 7, 10], - [15, 22]]) - - method - A function associated with an object. For example, each ndarray has a - method called ``repeat``:: - - >>> x = np.array([1, 2, 3]) - >>> x.repeat(2) - array([1, 1, 2, 2, 3, 3]) - - ndarray - See *array*. - - record array - An :term:`ndarray` with :term:`structured data type` which has been - subclassed as ``np.recarray`` and whose dtype is of type ``np.record``, - making the fields of its data type to be accessible by attribute. - - reference - If ``a`` is a reference to ``b``, then ``(a is b) == True``. Therefore, - ``a`` and ``b`` are different names for the same Python object. - - row-major - A way to represent items in a N-dimensional array in the 1-dimensional - computer memory. In row-major order, the rightmost index "varies - the fastest": for example the array:: - - [[1, 2, 3], - [4, 5, 6]] - - is represented in the row-major order as:: - - [1, 2, 3, 4, 5, 6] - - Row-major order is also known as the C order, as the C programming - language uses it. New NumPy arrays are by default in row-major order. - - self - Often seen in method signatures, ``self`` refers to the instance - of the associated class. For example: - - >>> class Paintbrush(object): - ... color = 'blue' - ... - ... def paint(self): - ... print("Painting the city %s!" % self.color) - ... - >>> p = Paintbrush() - >>> p.color = 'red' - >>> p.paint() # self refers to 'p' - Painting the city red! - - slice - Used to select only certain elements from a sequence: - - >>> x = range(5) - >>> x - [0, 1, 2, 3, 4] - - >>> x[1:3] # slice from 1 to 3 (excluding 3 itself) - [1, 2] - - >>> x[1:5:2] # slice from 1 to 5, but skipping every second element - [1, 3] - - >>> x[::-1] # slice a sequence in reverse - [4, 3, 2, 1, 0] - - Arrays may have more than one dimension, each which can be sliced - individually: - - >>> x = np.array([[1, 2], [3, 4]]) - >>> x - array([[1, 2], - [3, 4]]) - - >>> x[:, 1] - array([2, 4]) - - structure - See :term:`structured data type` - - structured data type - A data type composed of other datatypes - - subarray data type - A :term:`structured data type` may contain a :term:`ndarray` with its - own dtype and shape: - - >>> dt = np.dtype([('a', np.int32), ('b', np.float32, (3,))]) - >>> np.zeros(3, dtype=dt) - array([(0, [0., 0., 0.]), (0, [0., 0., 0.]), (0, [0., 0., 0.])], - dtype=[('a', '` which is an alias to the name and is - commonly used for plotting. - - tuple - A sequence that may contain a variable number of types of any - kind. A tuple is immutable, i.e., once constructed it cannot be - changed. Similar to a list, it can be indexed and sliced:: - - >>> x = (1, 'one', [1, 2]) - >>> x - (1, 'one', [1, 2]) - - >>> x[0] - 1 - - >>> x[:2] - (1, 'one') - - A useful concept is "tuple unpacking", which allows variables to - be assigned to the contents of a tuple:: - - >>> x, y = (1, 2) - >>> x, y = 1, 2 - - This is often used when a function returns multiple values: - - >>> def return_many(): - ... return 1, 'alpha', None - - >>> a, b, c = return_many() - >>> a, b, c - (1, 'alpha', None) - - >>> a - 1 - >>> b - 'alpha' - - ufunc - Universal function. A fast element-wise, :term:`vectorized - ` array operation. Examples include ``add``, ``sin`` and - ``logical_or``. - - vectorization - Optimizing a looping block by specialized code. In a traditional sense, - vectorization performs the same operation on multiple elements with - fixed strides between them via specialized hardware. Compilers know how - to take advantage of well-constructed loops to implement such - optimizations. NumPy uses :ref:`vectorization ` - to mean any optimization via specialized code performing the same - operations on multiple elements, typically achieving speedups by - avoiding some of the overhead in looking up and converting the elements. - - view - An array that does not own its data, but refers to another array's - data instead. For example, we may create a view that only shows - every second element of another array:: - - >>> x = np.arange(5) - >>> x - array([0, 1, 2, 3, 4]) - - >>> y = x[::2] - >>> y - array([0, 2, 4]) - - >>> x[0] = 3 # changing x changes y as well, since y is a view on x - >>> y - array([3, 2, 4]) - - wrapper - Python is a high-level (highly abstracted, or English-like) language. - This abstraction comes at a price in execution speed, and sometimes - it becomes necessary to use lower level languages to do fast - computations. A wrapper is code that provides a bridge between - high and the low level languages, allowing, e.g., Python to execute - code written in C or Fortran. - - Examples include ctypes, SWIG and Cython (which wraps C and C++) - and f2py (which wraps Fortran). - -""" -from __future__ import division, absolute_import, print_function diff --git a/venv/lib/python3.7/site-packages/numpy/doc/indexing.py b/venv/lib/python3.7/site-packages/numpy/doc/indexing.py deleted file mode 100644 index 6760156..0000000 --- a/venv/lib/python3.7/site-packages/numpy/doc/indexing.py +++ /dev/null @@ -1,449 +0,0 @@ -""" -============== -Array indexing -============== - -Array indexing refers to any use of the square brackets ([]) to index -array values. There are many options to indexing, which give numpy -indexing great power, but with power comes some complexity and the -potential for confusion. This section is just an overview of the -various options and issues related to indexing. Aside from single -element indexing, the details on most of these options are to be -found in related sections. - -Assignment vs referencing -========================= - -Most of the following examples show the use of indexing when -referencing data in an array. The examples work just as well -when assigning to an array. See the section at the end for -specific examples and explanations on how assignments work. - -Single element indexing -======================= - -Single element indexing for a 1-D array is what one expects. It work -exactly like that for other standard Python sequences. It is 0-based, -and accepts negative indices for indexing from the end of the array. :: - - >>> x = np.arange(10) - >>> x[2] - 2 - >>> x[-2] - 8 - -Unlike lists and tuples, numpy arrays support multidimensional indexing -for multidimensional arrays. That means that it is not necessary to -separate each dimension's index into its own set of square brackets. :: - - >>> x.shape = (2,5) # now x is 2-dimensional - >>> x[1,3] - 8 - >>> x[1,-1] - 9 - -Note that if one indexes a multidimensional array with fewer indices -than dimensions, one gets a subdimensional array. For example: :: - - >>> x[0] - array([0, 1, 2, 3, 4]) - -That is, each index specified selects the array corresponding to the -rest of the dimensions selected. In the above example, choosing 0 -means that the remaining dimension of length 5 is being left unspecified, -and that what is returned is an array of that dimensionality and size. -It must be noted that the returned array is not a copy of the original, -but points to the same values in memory as does the original array. -In this case, the 1-D array at the first position (0) is returned. -So using a single index on the returned array, results in a single -element being returned. That is: :: - - >>> x[0][2] - 2 - -So note that ``x[0,2] = x[0][2]`` though the second case is more -inefficient as a new temporary array is created after the first index -that is subsequently indexed by 2. - -Note to those used to IDL or Fortran memory order as it relates to -indexing. NumPy uses C-order indexing. That means that the last -index usually represents the most rapidly changing memory location, -unlike Fortran or IDL, where the first index represents the most -rapidly changing location in memory. This difference represents a -great potential for confusion. - -Other indexing options -====================== - -It is possible to slice and stride arrays to extract arrays of the -same number of dimensions, but of different sizes than the original. -The slicing and striding works exactly the same way it does for lists -and tuples except that they can be applied to multiple dimensions as -well. A few examples illustrates best: :: - - >>> x = np.arange(10) - >>> x[2:5] - array([2, 3, 4]) - >>> x[:-7] - array([0, 1, 2]) - >>> x[1:7:2] - array([1, 3, 5]) - >>> y = np.arange(35).reshape(5,7) - >>> y[1:5:2,::3] - array([[ 7, 10, 13], - [21, 24, 27]]) - -Note that slices of arrays do not copy the internal array data but -only produce new views of the original data. This is different from -list or tuple slicing and an explicit ``copy()`` is recommended if -the original data is not required anymore. - -It is possible to index arrays with other arrays for the purposes of -selecting lists of values out of arrays into new arrays. There are -two different ways of accomplishing this. One uses one or more arrays -of index values. The other involves giving a boolean array of the proper -shape to indicate the values to be selected. Index arrays are a very -powerful tool that allow one to avoid looping over individual elements in -arrays and thus greatly improve performance. - -It is possible to use special features to effectively increase the -number of dimensions in an array through indexing so the resulting -array acquires the shape needed for use in an expression or with a -specific function. - -Index arrays -============ - -NumPy arrays may be indexed with other arrays (or any other sequence- -like object that can be converted to an array, such as lists, with the -exception of tuples; see the end of this document for why this is). The -use of index arrays ranges from simple, straightforward cases to -complex, hard-to-understand cases. For all cases of index arrays, what -is returned is a copy of the original data, not a view as one gets for -slices. - -Index arrays must be of integer type. Each value in the array indicates -which value in the array to use in place of the index. To illustrate: :: - - >>> x = np.arange(10,1,-1) - >>> x - array([10, 9, 8, 7, 6, 5, 4, 3, 2]) - >>> x[np.array([3, 3, 1, 8])] - array([7, 7, 9, 2]) - - -The index array consisting of the values 3, 3, 1 and 8 correspondingly -create an array of length 4 (same as the index array) where each index -is replaced by the value the index array has in the array being indexed. - -Negative values are permitted and work as they do with single indices -or slices: :: - - >>> x[np.array([3,3,-3,8])] - array([7, 7, 4, 2]) - -It is an error to have index values out of bounds: :: - - >>> x[np.array([3, 3, 20, 8])] - : index 20 out of bounds 0<=index<9 - -Generally speaking, what is returned when index arrays are used is -an array with the same shape as the index array, but with the type -and values of the array being indexed. As an example, we can use a -multidimensional index array instead: :: - - >>> x[np.array([[1,1],[2,3]])] - array([[9, 9], - [8, 7]]) - -Indexing Multi-dimensional arrays -================================= - -Things become more complex when multidimensional arrays are indexed, -particularly with multidimensional index arrays. These tend to be -more unusual uses, but they are permitted, and they are useful for some -problems. We'll start with the simplest multidimensional case (using -the array y from the previous examples): :: - - >>> y[np.array([0,2,4]), np.array([0,1,2])] - array([ 0, 15, 30]) - -In this case, if the index arrays have a matching shape, and there is -an index array for each dimension of the array being indexed, the -resultant array has the same shape as the index arrays, and the values -correspond to the index set for each position in the index arrays. In -this example, the first index value is 0 for both index arrays, and -thus the first value of the resultant array is y[0,0]. The next value -is y[2,1], and the last is y[4,2]. - -If the index arrays do not have the same shape, there is an attempt to -broadcast them to the same shape. If they cannot be broadcast to the -same shape, an exception is raised: :: - - >>> y[np.array([0,2,4]), np.array([0,1])] - : shape mismatch: objects cannot be - broadcast to a single shape - -The broadcasting mechanism permits index arrays to be combined with -scalars for other indices. The effect is that the scalar value is used -for all the corresponding values of the index arrays: :: - - >>> y[np.array([0,2,4]), 1] - array([ 1, 15, 29]) - -Jumping to the next level of complexity, it is possible to only -partially index an array with index arrays. It takes a bit of thought -to understand what happens in such cases. For example if we just use -one index array with y: :: - - >>> y[np.array([0,2,4])] - array([[ 0, 1, 2, 3, 4, 5, 6], - [14, 15, 16, 17, 18, 19, 20], - [28, 29, 30, 31, 32, 33, 34]]) - -What results is the construction of a new array where each value of -the index array selects one row from the array being indexed and the -resultant array has the resulting shape (number of index elements, -size of row). - -An example of where this may be useful is for a color lookup table -where we want to map the values of an image into RGB triples for -display. The lookup table could have a shape (nlookup, 3). Indexing -such an array with an image with shape (ny, nx) with dtype=np.uint8 -(or any integer type so long as values are with the bounds of the -lookup table) will result in an array of shape (ny, nx, 3) where a -triple of RGB values is associated with each pixel location. - -In general, the shape of the resultant array will be the concatenation -of the shape of the index array (or the shape that all the index arrays -were broadcast to) with the shape of any unused dimensions (those not -indexed) in the array being indexed. - -Boolean or "mask" index arrays -============================== - -Boolean arrays used as indices are treated in a different manner -entirely than index arrays. Boolean arrays must be of the same shape -as the initial dimensions of the array being indexed. In the -most straightforward case, the boolean array has the same shape: :: - - >>> b = y>20 - >>> y[b] - array([21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34]) - -Unlike in the case of integer index arrays, in the boolean case, the -result is a 1-D array containing all the elements in the indexed array -corresponding to all the true elements in the boolean array. The -elements in the indexed array are always iterated and returned in -:term:`row-major` (C-style) order. The result is also identical to -``y[np.nonzero(b)]``. As with index arrays, what is returned is a copy -of the data, not a view as one gets with slices. - -The result will be multidimensional if y has more dimensions than b. -For example: :: - - >>> b[:,5] # use a 1-D boolean whose first dim agrees with the first dim of y - array([False, False, False, True, True]) - >>> y[b[:,5]] - array([[21, 22, 23, 24, 25, 26, 27], - [28, 29, 30, 31, 32, 33, 34]]) - -Here the 4th and 5th rows are selected from the indexed array and -combined to make a 2-D array. - -In general, when the boolean array has fewer dimensions than the array -being indexed, this is equivalent to y[b, ...], which means -y is indexed by b followed by as many : as are needed to fill -out the rank of y. -Thus the shape of the result is one dimension containing the number -of True elements of the boolean array, followed by the remaining -dimensions of the array being indexed. - -For example, using a 2-D boolean array of shape (2,3) -with four True elements to select rows from a 3-D array of shape -(2,3,5) results in a 2-D result of shape (4,5): :: - - >>> x = np.arange(30).reshape(2,3,5) - >>> x - array([[[ 0, 1, 2, 3, 4], - [ 5, 6, 7, 8, 9], - [10, 11, 12, 13, 14]], - [[15, 16, 17, 18, 19], - [20, 21, 22, 23, 24], - [25, 26, 27, 28, 29]]]) - >>> b = np.array([[True, True, False], [False, True, True]]) - >>> x[b] - array([[ 0, 1, 2, 3, 4], - [ 5, 6, 7, 8, 9], - [20, 21, 22, 23, 24], - [25, 26, 27, 28, 29]]) - -For further details, consult the numpy reference documentation on array indexing. - -Combining index arrays with slices -================================== - -Index arrays may be combined with slices. For example: :: - - >>> y[np.array([0,2,4]),1:3] - array([[ 1, 2], - [15, 16], - [29, 30]]) - -In effect, the slice is converted to an index array -np.array([[1,2]]) (shape (1,2)) that is broadcast with the index array -to produce a resultant array of shape (3,2). - -Likewise, slicing can be combined with broadcasted boolean indices: :: - - >>> b = y > 20 - >>> b - array([[False, False, False, False, False, False, False], - [False, False, False, False, False, False, False], - [False, False, False, False, False, False, False], - [ True, True, True, True, True, True, True], - [ True, True, True, True, True, True, True]]) - >>> y[b[:,5],1:3] - array([[22, 23], - [29, 30]]) - -Structural indexing tools -========================= - -To facilitate easy matching of array shapes with expressions and in -assignments, the np.newaxis object can be used within array indices -to add new dimensions with a size of 1. For example: :: - - >>> y.shape - (5, 7) - >>> y[:,np.newaxis,:].shape - (5, 1, 7) - -Note that there are no new elements in the array, just that the -dimensionality is increased. This can be handy to combine two -arrays in a way that otherwise would require explicitly reshaping -operations. For example: :: - - >>> x = np.arange(5) - >>> x[:,np.newaxis] + x[np.newaxis,:] - array([[0, 1, 2, 3, 4], - [1, 2, 3, 4, 5], - [2, 3, 4, 5, 6], - [3, 4, 5, 6, 7], - [4, 5, 6, 7, 8]]) - -The ellipsis syntax maybe used to indicate selecting in full any -remaining unspecified dimensions. For example: :: - - >>> z = np.arange(81).reshape(3,3,3,3) - >>> z[1,...,2] - array([[29, 32, 35], - [38, 41, 44], - [47, 50, 53]]) - -This is equivalent to: :: - - >>> z[1,:,:,2] - array([[29, 32, 35], - [38, 41, 44], - [47, 50, 53]]) - -Assigning values to indexed arrays -================================== - -As mentioned, one can select a subset of an array to assign to using -a single index, slices, and index and mask arrays. The value being -assigned to the indexed array must be shape consistent (the same shape -or broadcastable to the shape the index produces). For example, it is -permitted to assign a constant to a slice: :: - - >>> x = np.arange(10) - >>> x[2:7] = 1 - -or an array of the right size: :: - - >>> x[2:7] = np.arange(5) - -Note that assignments may result in changes if assigning -higher types to lower types (like floats to ints) or even -exceptions (assigning complex to floats or ints): :: - - >>> x[1] = 1.2 - >>> x[1] - 1 - >>> x[1] = 1.2j - : can't convert complex to long; use - long(abs(z)) - - -Unlike some of the references (such as array and mask indices) -assignments are always made to the original data in the array -(indeed, nothing else would make sense!). Note though, that some -actions may not work as one may naively expect. This particular -example is often surprising to people: :: - - >>> x = np.arange(0, 50, 10) - >>> x - array([ 0, 10, 20, 30, 40]) - >>> x[np.array([1, 1, 3, 1])] += 1 - >>> x - array([ 0, 11, 20, 31, 40]) - -Where people expect that the 1st location will be incremented by 3. -In fact, it will only be incremented by 1. The reason is because -a new array is extracted from the original (as a temporary) containing -the values at 1, 1, 3, 1, then the value 1 is added to the temporary, -and then the temporary is assigned back to the original array. Thus -the value of the array at x[1]+1 is assigned to x[1] three times, -rather than being incremented 3 times. - -Dealing with variable numbers of indices within programs -======================================================== - -The index syntax is very powerful but limiting when dealing with -a variable number of indices. For example, if you want to write -a function that can handle arguments with various numbers of -dimensions without having to write special case code for each -number of possible dimensions, how can that be done? If one -supplies to the index a tuple, the tuple will be interpreted -as a list of indices. For example (using the previous definition -for the array z): :: - - >>> indices = (1,1,1,1) - >>> z[indices] - 40 - -So one can use code to construct tuples of any number of indices -and then use these within an index. - -Slices can be specified within programs by using the slice() function -in Python. For example: :: - - >>> indices = (1,1,1,slice(0,2)) # same as [1,1,1,0:2] - >>> z[indices] - array([39, 40]) - -Likewise, ellipsis can be specified by code by using the Ellipsis -object: :: - - >>> indices = (1, Ellipsis, 1) # same as [1,...,1] - >>> z[indices] - array([[28, 31, 34], - [37, 40, 43], - [46, 49, 52]]) - -For this reason it is possible to use the output from the np.nonzero() -function directly as an index since it always returns a tuple of index -arrays. - -Because the special treatment of tuples, they are not automatically -converted to an array as a list would be. As an example: :: - - >>> z[[1,1,1,1]] # produces a large array - array([[[[27, 28, 29], - [30, 31, 32], ... - >>> z[(1,1,1,1)] # returns a single value - 40 - -""" -from __future__ import division, absolute_import, print_function diff --git a/venv/lib/python3.7/site-packages/numpy/doc/internals.py b/venv/lib/python3.7/site-packages/numpy/doc/internals.py deleted file mode 100644 index a14fee7..0000000 --- a/venv/lib/python3.7/site-packages/numpy/doc/internals.py +++ /dev/null @@ -1,163 +0,0 @@ -""" -=============== -Array Internals -=============== - -Internal organization of numpy arrays -===================================== - -It helps to understand a bit about how numpy arrays are handled under the covers to help understand numpy better.

Those wishing to understand the full details are referred to Travis Oliphant's book "Guide to NumPy". - -NumPy arrays consist of two major components, the raw array data (from now on, -referred to as the data buffer), and the information about the raw array data. -The data buffer is typically what people think of as arrays in C or Fortran, -a contiguous (and fixed) block of memory containing fixed sized data items. -NumPy also contains a significant set of data that describes how to interpret -the data in the data buffer.

This is why it is necessary to force copies through -use of the .copy() method if one really wants to make a new and independent -copy of the data buffer. - -New views into arrays mean the object reference counts for the data buffer -increase. Simply doing away with the original array object will not remove the -data buffer if other views of it still exist. - -Multidimensional Array Indexing Order Issues -============================================ - -What is the right way to index -multi-dimensional arrays? Before you jump to conclusions about the one and -true way to index multi-dimensional arrays, it pays to understand why this is -a confusing issue. This section will try to explain in detail how numpy -indexing works and why we adopt the convention we do for images, and when it -may be appropriate to adopt other conventions. - -The first thing to understand is -that there are two conflicting conventions for indexing 2-dimensional arrays. -Matrix notation uses the first index to indicate which row is being selected and -the second index to indicate which column is selected. This is opposite the -geometrically oriented-convention for images where people generally think the -first index represents x position (i.e., column) and the second represents y -position (i.e., row). This alone is the source of much confusion; -matrix-oriented users and image-oriented users expect two different things with -regard to indexing. - -The second issue to understand is how indices correspond -to the order the array is stored in memory. In Fortran the first index is the -most rapidly varying index when moving through the elements of a two -dimensional array as it is stored in memory. If you adopt the matrix -convention for indexing, then this means the matrix is stored one column at a -time (since the first index moves to the next row as it changes). Thus Fortran -is considered a Column-major language. C has just the opposite convention. In -C, the last index changes most rapidly as one moves through the array as -stored in memory. Thus C is a Row-major language. The matrix is stored by -rows. Note that in both cases it presumes that the matrix convention for -indexing is being used, i.e., for both Fortran and C, the first index is the -row. Note this convention implies that the indexing convention is invariant -and that the data order changes to keep that so. - -But that's not the only way -to look at it. Suppose one has large two-dimensional arrays (images or -matrices) stored in data files. Suppose the data are stored by rows rather than -by columns. If we are to preserve our index convention (whether matrix or -image) that means that depending on the language we use, we may be forced to -reorder the data if it is read into memory to preserve our indexing -convention. For example if we read row-ordered data into memory without -reordering, it will match the matrix indexing convention for C, but not for -Fortran. Conversely, it will match the image indexing convention for Fortran, -but not for C. For C, if one is using data stored in row order, and one wants -to preserve the image index convention, the data must be reordered when -reading into memory. - -In the end, which you do for Fortran or C depends on -which is more important, not reordering data or preserving the indexing -convention. For large images, reordering data is potentially expensive, and -often the indexing convention is inverted to avoid that. - -The situation with -numpy makes this issue yet more complicated. The internal machinery of numpy -arrays is flexible enough to accept any ordering of indices. One can simply -reorder indices by manipulating the internal stride information for arrays -without reordering the data at all. NumPy will know how to map the new index -order to the data without moving the data. - -So if this is true, why not choose -the index order that matches what you most expect? In particular, why not define -row-ordered images to use the image convention? (This is sometimes referred -to as the Fortran convention vs the C convention, thus the 'C' and 'FORTRAN' -order options for array ordering in numpy.) The drawback of doing this is -potential performance penalties. It's common to access the data sequentially, -either implicitly in array operations or explicitly by looping over rows of an -image. When that is done, then the data will be accessed in non-optimal order. -As the first index is incremented, what is actually happening is that elements -spaced far apart in memory are being sequentially accessed, with usually poor -memory access speeds. For example, for a two dimensional image 'im' defined so -that im[0, 10] represents the value at x=0, y=10. To be consistent with usual -Python behavior then im[0] would represent a column at x=0. Yet that data -would be spread over the whole array since the data are stored in row order. -Despite the flexibility of numpy's indexing, it can't really paper over the fact -basic operations are rendered inefficient because of data order or that getting -contiguous subarrays is still awkward (e.g., im[:,0] for the first row, vs -im[0]), thus one can't use an idiom such as for row in im; for col in im does -work, but doesn't yield contiguous column data. - -As it turns out, numpy is -smart enough when dealing with ufuncs to determine which index is the most -rapidly varying one in memory and uses that for the innermost loop. Thus for -ufuncs there is no large intrinsic advantage to either approach in most cases. -On the other hand, use of .flat with an FORTRAN ordered array will lead to -non-optimal memory access as adjacent elements in the flattened array (iterator, -actually) are not contiguous in memory. - -Indeed, the fact is that Python -indexing on lists and other sequences naturally leads to an outside-to inside -ordering (the first index gets the largest grouping, the next the next largest, -and the last gets the smallest element). Since image data are normally stored -by rows, this corresponds to position within rows being the last item indexed. - -If you do want to use Fortran ordering realize that -there are two approaches to consider: 1) accept that the first index is just not -the most rapidly changing in memory and have all your I/O routines reorder -your data when going from memory to disk or visa versa, or use numpy's -mechanism for mapping the first index to the most rapidly varying data. We -recommend the former if possible. The disadvantage of the latter is that many -of numpy's functions will yield arrays without Fortran ordering unless you are -careful to use the 'order' keyword. Doing this would be highly inconvenient. - -Otherwise we recommend simply learning to reverse the usual order of indices -when accessing elements of an array. Granted, it goes against the grain, but -it is more in line with Python semantics and the natural order of the data. - -""" -from __future__ import division, absolute_import, print_function diff --git a/venv/lib/python3.7/site-packages/numpy/doc/misc.py b/venv/lib/python3.7/site-packages/numpy/doc/misc.py deleted file mode 100644 index a76abe1..0000000 --- a/venv/lib/python3.7/site-packages/numpy/doc/misc.py +++ /dev/null @@ -1,227 +0,0 @@ -""" -============= -Miscellaneous -============= - -IEEE 754 Floating Point Special Values --------------------------------------- - -Special values defined in numpy: nan, inf, - -NaNs can be used as a poor-man's mask (if you don't care what the -original value was) - -Note: cannot use equality to test NaNs.

On this page we explain the machinery -that allows you to subclass ndarray, and the implications for -implementing a subclass. - -ndarrays and object creation -============================ - -Subclassing ndarray is complicated by the fact that new instances of -ndarray classes can come about in three different ways. These are: - -#. Explicit constructor call - as in ``MySubClass(params)``. This is - the usual route to Python instance creation. -#. View casting - casting an existing ndarray as a given subclass -#. New from template - creating a new instance from a template - instance. Examples include returning slices from a subclassed array, - creating return types from ufuncs, and copying arrays. See - :ref:`new-from-template` for more details - -The last two are characteristics of ndarrays - in order to support -things like array slicing. The complications of subclassing ndarray are -due to the mechanisms numpy has to support these latter two routes of -instance creation. - -.. _view-casting: - -View casting ------------- - -*View casting* is the standard ndarray mechanism by which you take an -ndarray of any subclass, and return a view of the array as another -(specified) subclass: - ->>> import numpy as np ->>> # create a completely useless ndarray subclass ->>> class C(np.ndarray): pass ->>> # create a standard ndarray ->>> arr = np.zeros((3,)) ->>> # take a view of it, as our useless subclass ->>> c_arr = arr.view(C) ->>> type(c_arr) - - -.. _new-from-template: - -Creating new from template --------------------------- - -New instances of an ndarray subclass can also come about by a very -similar mechanism to :ref:`view-casting`, when numpy finds it needs to -create a new instance from a template instance. The most obvious place -this has to happen is when you are taking slices of subclassed arrays. -For example: - ->>> v = c_arr[1:] ->>> type(v) # the view is of type 'C' - ->>> v is c_arr # but it's a new instance -False - -The slice is a *view* onto the original ``c_arr`` data. So, when we -take a view from the ndarray, we return a new ndarray, of the same -class, that points to the data in the original. - -There are other points in the use of ndarrays where we need such views, -such as copying arrays (``c_arr.copy()``), creating ufunc output arrays -(see also :ref:`array-wrap`), and reducing methods (like -``c_arr.mean()``. - -Relationship of view casting and new-from-template --------------------------------------------------- - -These paths both use the same machinery. We make the distinction here, -because they result in different input to your methods. Specifically, -:ref:`view-casting` means you have created a new instance of your array -type from any potential subclass of ndarray. :ref:`new-from-template` -means you have created a new instance of your class from a pre-existing -instance, allowing you - for example - to copy across attributes that -are particular to your subclass. - -Implications for subclassing ----------------------------- - -If we subclass ndarray, we need to deal not only with explicit -construction of our array type, but also :ref:`view-casting` or -:ref:`new-from-template`. NumPy has the machinery to do this, and this -machinery that makes subclassing slightly non-standard. - -There are two aspects to the machinery that ndarray uses to support -views and new-from-template in subclasses. - -The first is the use of the ``ndarray.__new__`` method for the main work -of object initialization, rather then the more usual ``__init__`` -method. The second is the use of the ``__array_finalize__`` method to -allow subclasses to clean up after the creation of views and new -instances from templates. - -A brief Python primer on ``__new__`` and ``__init__`` -===================================================== - -``__new__`` is a standard Python method, and, if present, is called -before ``__init__`` when we create a class instance. See the `python -__new__ documentation -`_ for more detail. - -For example, consider the following Python code: - -.. testcode:: - - class C(object): - def __new__(cls, *args): - print('Cls in __new__:', cls) - print('Args in __new__:', args) - # The `object` type __new__ method takes a single argument. - return object.__new__(cls) - - def __init__(self, *args): - print('type(self) in __init__:', type(self)) - print('Args in __init__:', args) - -meaning that we get: - ->>> c = C('hello') -Cls in __new__: -Args in __new__: ('hello',) -type(self) in __init__: -Args in __init__: ('hello',) - -When we call ``C('hello')``, the ``__new__`` method gets its own class -as first argument, and the passed argument, which is the string -``'hello'``. After python calls ``__new__``, it usually (see below) -calls our ``__init__`` method, with the output of ``__new__`` as the -first argument (now a class instance), and the passed arguments -following. - -As you can see, the object can be initialized in the ``__new__`` -method or the ``__init__`` method, or both, and in fact ndarray does -not have an ``__init__`` method, because all the initialization is -done in the ``__new__`` method. - -Why use ``__new__`` rather than just the usual ``__init__``? Because -in some cases, as for ndarray, we want to be able to return an object -of some other class. Consider the following: - -.. testcode:: - - class D(C): - def __new__(cls, *args): - print('D cls is:', cls) - print('D args in __new__:', args) - return C.__new__(C, *args) - - def __init__(self, *args): - # we never get here - print('In D __init__') - -meaning that: - ->>> obj = D('hello') -D cls is: -D args in __new__: ('hello',) -Cls in __new__: -Args in __new__: ('hello',) ->>> type(obj) - - -The definition of ``C`` is the same as before, but for ``D``, the -``__new__`` method returns an instance of class ``C`` rather than -``D``. Note that the ``__init__`` method of ``D`` does not get -called. In general, when the ``__new__`` method returns an object of -class other than the class in which it is defined, the ``__init__`` -method of that class is not called. - -This is how subclasses of the ndarray class are able to return views -that preserve the class type. When taking a view, the standard -ndarray machinery creates the new ndarray object with something -like:: - - obj = ndarray.__new__(subtype, shape, ... - -where ``subdtype`` is the subclass. Thus the returned view is of the -same class as the subclass, rather than being of class ``ndarray``. - -That solves the problem of returning views of the same type, but now -we have a new problem. The machinery of ndarray can set the class -this way, in its standard methods for taking views, but the ndarray -``__new__`` method knows nothing of what we have done in our own -``__new__`` method in order to set attributes, and so on. (Aside - -why not call ``obj = subdtype.__new__(...`` then? Because we may not -have a ``__new__`` method with the same call signature). - -The role of ``__array_finalize__`` -================================== - -``__array_finalize__`` is the mechanism that numpy provides to allow -subclasses to handle the various ways that new instances get created. - -Remember that subclass instances can come about in these three ways: - -#. explicit constructor call (``obj = MySubClass(params)``). This will - call the usual sequence of ``MySubClass.__new__`` then (if it exists) - ``MySubClass.__init__``. -#. :ref:`view-casting` -#. :ref:`new-from-template` - -Our ``MySubClass.__new__`` method only gets called in the case of the -explicit constructor call, so we can't rely on ``MySubClass.__new__`` or -``MySubClass.__init__`` to deal with the view casting and -new-from-template. It turns out that ``MySubClass.__array_finalize__`` -*does* get called for all three methods of object creation, so this is -where our object creation housekeeping usually goes. - -* For the explicit constructor call, our subclass will need to create a - new ndarray instance of its own class. In practice this means that - we, the authors of the code, will need to make a call to - ``ndarray.__new__(MySubClass,...)``, a class-hierarchy prepared call to - ``super(MySubClass, cls).__new__(cls, ...)``, or do view casting of an - existing array (see below) -* For view casting and new-from-template, the equivalent of - ``ndarray.__new__(MySubClass,...`` is called, at the C level. - -The arguments that ``__array_finalize__`` receives differ for the three -methods of instance creation above. - -The following code allows us to look at the call sequences and arguments: - -.. testcode:: - - import numpy as np - - class C(np.ndarray): - def __new__(cls, *args, **kwargs): - print('In __new__ with class %s' % cls) - return super(C, cls).__new__(cls, *args, **kwargs) - - def __init__(self, *args, **kwargs): - # in practice you probably will not need or want an __init__ - # method for your subclass - print('In __init__ with class %s' % self.__class__) - - def __array_finalize__(self, obj): - print('In array_finalize:') - print(' self type is %s' % type(self)) - print(' obj type is %s' % type(obj)) - - -Now: - ->>> # Explicit constructor ->>> c = C((10,)) -In __new__ with class -In array_finalize: - self type is - obj type is -In __init__ with class ->>> # View casting ->>> a = np.arange(10) ->>> cast_a = a.view(C) -In array_finalize: - self type is - obj type is ->>> # Slicing (example of new-from-template) ->>> cv = c[:1] -In array_finalize: - self type is - obj type is - -The signature of ``__array_finalize__`` is:: - - def __array_finalize__(self, obj): - -One sees that the ``super`` call, which goes to -``ndarray.__new__``, passes ``__array_finalize__`` the new object, of our -own class (``self``) as well as the object from which the view has been -taken (``obj``). As you can see from the output above, the ``self`` is -always a newly created instance of our subclass, and the type of ``obj`` -differs for the three instance creation methods: - -* When called from the explicit constructor, ``obj`` is ``None`` -* When called from view casting, ``obj`` can be an instance of any - subclass of ndarray, including our own. -* When called in new-from-template, ``obj`` is another instance of our - own subclass, that we might use to update the new ``self`` instance. - -Because ``__array_finalize__`` is the only method that always sees new -instances being created, it is the sensible place to fill in instance -defaults for new object attributes, among other tasks. - -This may be clearer with an example. - -Simple example - adding an extra attribute to ndarray ------------------------------------------------------ - -.. testcode:: - - import numpy as np - - class InfoArray(np.ndarray): - - def __new__(subtype, shape, dtype=float, buffer=None, offset=0, - strides=None, order=None, info=None): - # Create the ndarray instance of our type, given the usual - # ndarray input arguments. This will call the standard - # ndarray constructor, but return an object of our type. - # It also triggers a call to InfoArray.__array_finalize__ - obj = super(InfoArray, subtype).__new__(subtype, shape, dtype, - buffer, offset, strides, - order) - # set the new 'info' attribute to the value passed - obj.info = info - # Finally, we must return the newly created object: - return obj - - def __array_finalize__(self, obj): - # ``self`` is a new object resulting from - # ndarray.__new__(InfoArray, ...), therefore it only has - # attributes that the ndarray.__new__ constructor gave it - - # i.e. those of a standard ndarray. - # - # We could have got to the ndarray.__new__ call in 3 ways: - # From an explicit constructor - e.g. InfoArray(): - # obj is None - # (we're in the middle of the InfoArray.__new__ - # constructor, and self.info will be set when we return to - # InfoArray.__new__) - if obj is None: return - # From view casting - e.g arr.view(InfoArray): - # obj is arr - # (type(obj) can be InfoArray) - # From new-from-template - e.g infoarr[:3] - # type(obj) is InfoArray - # - # Note that it is here, rather than in the __new__ method, - # that we set the default value for 'info', because this - # method sees all creation of default objects - with the - # InfoArray.__new__ constructor, but also with - # arr.view(InfoArray). - self.info = getattr(obj, 'info', None) - # We do not need to return anything - - -Using the object looks like this: - - >>> obj = InfoArray(shape=(3,)) # explicit constructor - >>> type(obj) - - >>> obj.info is None - True - >>> obj = InfoArray(shape=(3,), info='information') - >>> obj.info - 'information' - >>> v = obj[1:] # new-from-template - here - slicing - >>> type(v) - - >>> v.info - 'information' - >>> arr = np.arange(10) - >>> cast_arr = arr.view(InfoArray) # view casting - >>> type(cast_arr) - - >>> cast_arr.info is None - True - -This class isn't very useful, because it has the same constructor as the -bare ndarray object, including passing in buffers and shapes and so on. -We would probably prefer the constructor to be able to take an already -formed ndarray from the usual numpy calls to ``np.array`` and return an -object. - -Slightly more realistic example - attribute added to existing array -------------------------------------------------------------------- - -Here is a class that takes a standard ndarray that already exists, casts -as our type, and adds an extra attribute. - -.. testcode:: - - import numpy as np - - class RealisticInfoArray(np.ndarray): - - def __new__(cls, input_array, info=None): - # Input array is an already formed ndarray instance - # We first cast to be our class type - obj = np.asarray(input_array).view(cls) - # add the new attribute to the created instance - obj.info = info - # Finally, we must return the newly created object: - return obj - - def __array_finalize__(self, obj): - # see InfoArray.__array_finalize__ for comments - if obj is None: return - self.info = getattr(obj, 'info', None) - - -So: - - >>> arr = np.arange(5) - >>> obj = RealisticInfoArray(arr, info='information') - >>> type(obj) - - >>> obj.info - 'information' - >>> v = obj[1:] - >>> type(v) - - >>> v.info - 'information' - -.. _array-ufunc: - -``__array_ufunc__`` for ufuncs ------------------------------- - - .. versionadded:: 1.13 - -A subclass can override what happens when executing numpy ufuncs on it by -overriding the default ``ndarray.__array_ufunc__`` method. This method is -executed *instead* of the ufunc and should return either the result of the -operation, or :obj:`NotImplemented` if the operation requested is not -implemented. - -The signature of ``__array_ufunc__`` is:: - - def __array_ufunc__(ufunc, method, *inputs, **kwargs): - - - *ufunc* is the ufunc object that was called. - - *method* is a string indicating how the Ufunc was called, either - ``"__call__"`` to indicate it was called directly, or one of its - :ref:`methods`: ``"reduce"``, ``"accumulate"``, - ``"reduceat"``, ``"outer"``, or ``"at"``. - - *inputs* is a tuple of the input arguments to the ``ufunc`` - - *kwargs* contains any optional or keyword arguments passed to the - function. This includes any ``out`` arguments, which are always - contained in a tuple. - -A typical implementation would convert any inputs or outputs that are -instances of one's own class, pass everything on to a superclass using -``super()``, and finally return the results after possible -back-conversion. An example, taken from the test case -``test_ufunc_override_with_super`` in ``core/tests/test_umath.py``, is the -following. - -.. testcode:: - - input numpy as np - - class A(np.ndarray): - def __array_ufunc__(self, ufunc, method, *inputs, **kwargs): - args = [] - in_no = [] - for i, input_ in enumerate(inputs): - if isinstance(input_, A): - in_no.append(i) - args.append(input_.view(np.ndarray)) - else: - args.append(input_) - - outputs = kwargs.pop('out', None) - out_no = [] - if outputs: - out_args = [] - for j, output in enumerate(outputs): - if isinstance(output, A): - out_no.append(j) - out_args.append(output.view(np.ndarray)) - else: - out_args.append(output) - kwargs['out'] = tuple(out_args) - else: - outputs = (None,) * ufunc.nout - - info = {} - if in_no: - info['inputs'] = in_no - if out_no: - info['outputs'] = out_no - - results = super(A, self).__array_ufunc__(ufunc, method, - *args, **kwargs) - if results is NotImplemented: - return NotImplemented - - if method == 'at': - if isinstance(inputs[0], A): - inputs[0].info = info - return - - if ufunc.nout == 1: - results = (results,) - - results = tuple((np.asarray(result).view(A) - if output is None else output) - for result, output in zip(results, outputs)) - if results and isinstance(results[0], A): - results[0].info = info - - return results[0] if len(results) == 1 else results - -So, this class does not actually do anything interesting: it just -converts any instances of its own to regular ndarray (otherwise, we'd -get infinite recursion!), and adds an ``info`` dictionary that tells -which inputs and outputs it converted. Hence, e.g., - ->>> a = np.arange(5.).view(A) ->>> b = np.sin(a) ->>> b.info -{'inputs': [0]} ->>> b = np.sin(np.arange(5.), out=(a,)) ->>> b.info -{'outputs': [0]} ->>> a = np.arange(5.).view(A) ->>> b = np.ones(1).view(A) ->>> c = a + b ->>> c.info -{'inputs': [0, 1]} ->>> a += b ->>> a.info -{'inputs': [0, 1], 'outputs': [0]} - -Note that another approach would be to to use ``getattr(ufunc, -methods)(*inputs, **kwargs)`` instead of the ``super`` call. For this example, -the result would be identical, but there is a difference if another operand -also defines ``__array_ufunc__``. E.g., lets assume that we evalulate -``np.add(a, b)``, where ``b`` is an instance of another class ``B`` that has -an override. If you use ``super`` as in the example, -``ndarray.__array_ufunc__`` will notice that ``b`` has an override, which -means it cannot evaluate the result itself. Thus, it will return -`NotImplemented` and so will our class ``A``. Then, control will be passed -over to ``b``, which either knows how to deal with us and produces a result, -or does not and returns `NotImplemented`, raising a ``TypeError``. - -If instead, we replace our ``super`` call with ``getattr(ufunc, method)``, we -effectively do ``np.add(a.view(np.ndarray), b)``. Again, ``B.__array_ufunc__`` -will be called, but now it sees an ``ndarray`` as the other argument. Likely, -it will know how to handle this, and return a new instance of the ``B`` class -to us. Our example class is not set up to handle this, but it might well be -the best approach if, e.g., one were to re-implement ``MaskedArray`` using -``__array_ufunc__``. - -As a final note: if the ``super`` route is suited to a given class, an -advantage of using it is that it helps in constructing class hierarchies. -E.g., suppose that our other class ``B`` also used the ``super`` in its -``__array_ufunc__`` implementation, and we created a class ``C`` that depended -on both, i.e., ``class C(A, B)`` (with, for simplicity, not another -``__array_ufunc__`` override). Then any ufunc on an instance of ``C`` would -pass on to ``A.__array_ufunc__``, the ``super`` call in ``A`` would go to -``B.__array_ufunc__``, and the ``super`` call in ``B`` would go to -``ndarray.__array_ufunc__``, thus allowing ``A`` and ``B`` to collaborate. - -.. _array-wrap: - -``__array_wrap__`` for ufuncs and other functions -------------------------------------------------- - -Prior to numpy 1.13, the behaviour of ufuncs could only be tuned using -``__array_wrap__`` and ``__array_prepare__``. These two allowed one to -change the output type of a ufunc, but, in contrast to -``__array_ufunc__``, did not allow one to make any changes to the inputs. -It is hoped to eventually deprecate these, but ``__array_wrap__`` is also -used by other numpy functions and methods, such as ``squeeze``, so at the -present time is still needed for full functionality. - -Conceptually, ``__array_wrap__`` "wraps up the action" in the sense of -allowing a subclass to set the type of the return value and update -attributes and metadata. Let's show how this works with an example. First -we return to the simpler example subclass, but with a different name and -some print statements: - -.. testcode:: - - import numpy as np - - class MySubClass(np.ndarray): - - def __new__(cls, input_array, info=None): - obj = np.asarray(input_array).view(cls) - obj.info = info - return obj - - def __array_finalize__(self, obj): - print('In __array_finalize__:') - print(' self is %s' % repr(self)) - print(' obj is %s' % repr(obj)) - if obj is None: return - self.info = getattr(obj, 'info', None) - - def __array_wrap__(self, out_arr, context=None): - print('In __array_wrap__:') - print(' self is %s' % repr(self)) - print(' arr is %s' % repr(out_arr)) - # then just call the parent - return super(MySubClass, self).__array_wrap__(self, out_arr, context) - -We run a ufunc on an instance of our new array: - ->>> obj = MySubClass(np.arange(5), info='spam') -In __array_finalize__: - self is MySubClass([0, 1, 2, 3, 4]) - obj is array([0, 1, 2, 3, 4]) ->>> arr2 = np.arange(5)+1 ->>> ret = np.add(arr2, obj) -In __array_wrap__: - self is MySubClass([0, 1, 2, 3, 4]) - arr is array([1, 3, 5, 7, 9]) -In __array_finalize__: - self is MySubClass([1, 3, 5, 7, 9]) - obj is MySubClass([0, 1, 2, 3, 4]) ->>> ret -MySubClass([1, 3, 5, 7, 9]) ->>> ret.info -'spam' - -Note that the ufunc (``np.add``) has called the ``__array_wrap__`` method -with arguments ``self`` as ``obj``, and ``out_arr`` as the (ndarray) result -of the addition. In turn, the default ``__array_wrap__`` -(``ndarray.__array_wrap__``) has cast the result to class ``MySubClass``, -and called ``__array_finalize__`` - hence the copying of the ``info`` -attribute. This has all happened at the C level. - -But, we could do anything we wanted: - -.. testcode:: - - class SillySubClass(np.ndarray): - - def __array_wrap__(self, arr, context=None): - return 'I lost your data' - ->>> arr1 = np.arange(5) ->>> obj = arr1.view(SillySubClass) ->>> arr2 = np.arange(5) ->>> ret = np.multiply(obj, arr2) ->>> ret -'I lost your data' - -So, by defining a specific ``__array_wrap__`` method for our subclass, -we can tweak the output from ufuncs. The ``__array_wrap__`` method -requires ``self``, then an argument - which is the result of the ufunc - -and an optional parameter *context*. This parameter is returned by -ufuncs as a 3-element tuple: (name of the ufunc, arguments of the ufunc, -domain of the ufunc), but is not set by other numpy functions. Though, -as seen above, it is possible to do otherwise, ``__array_wrap__`` should -return an instance of its containing class. See the masked array -subclass for an implementation. - -In addition to ``__array_wrap__``, which is called on the way out of the -ufunc, there is also an ``__array_prepare__`` method which is called on -the way into the ufunc, after the output arrays are created but before any -computation has been performed. The default implementation does nothing -but pass through the array. ``__array_prepare__`` should not attempt to -access the array data or resize the array, it is intended for setting the -output array type, updating attributes and metadata, and performing any -checks based on the input that may be desired before computation begins. -Like ``__array_wrap__``, ``__array_prepare__`` must return an ndarray or -subclass thereof or raise an error. - -Extra gotchas - custom ``__del__`` methods and ndarray.base ------------------------------------------------------------ - -One of the problems that ndarray solves is keeping track of memory -ownership of ndarrays and their views. Consider the case where we have -created an ndarray, ``arr`` and have taken a slice with ``v = arr[1:]``. -The two objects are looking at the same memory. NumPy keeps track of -where the data came from for a particular array or view, with the -``base`` attribute: - ->>> # A normal ndarray, that owns its own data ->>> arr = np.zeros((4,)) ->>> # In this case, base is None ->>> arr.base is None -True ->>> # We take a view ->>> v1 = arr[1:] ->>> # base now points to the array that it derived from ->>> v1.base is arr -True ->>> # Take a view of a view ->>> v2 = v1[1:] ->>> # base points to the view it derived from ->>> v2.base is v1 -True - -In general, if the array owns its own memory, as for ``arr`` in this -case, then ``arr.base`` will be None - there are some exceptions to this -- see the numpy book for more details. - -The ``base`` attribute is useful in being able to tell whether we have -a view or the original array. This in turn can be useful if we need -to know whether or not to do some specific cleanup when the subclassed -array is deleted. For example, we may only want to do the cleanup if -the original array is deleted, but not the views. For an example of -how this can work, have a look at the ``memmap`` class in -``numpy.core``. - -Subclassing and Downstream Compatibility ----------------------------------------- - -When sub-classing ``ndarray`` or creating duck-types that mimic the ``ndarray`` -interface, it is your responsibility to decide how aligned your APIs will be -with those of numpy. For convenience, many numpy functions that have a corresponding -``ndarray`` method (e.g., ``sum``, ``mean``, ``take``, ``reshape``) work by checking -if the first argument to a function has a method of the same name. If it exists, the -method is called instead of coercing the arguments to a numpy array. - -For example, if you want your sub-class or duck-type to be compatible with -numpy's ``sum`` function, the method signature for this object's ``sum`` method -should be the following: - -.. testcode:: - - def sum(self, axis=None, dtype=None, out=None, keepdims=False): - ... - -This is the exact same method signature for ``np.sum``, so now if a user calls -``np.sum`` on this object, numpy will call the object's own ``sum`` method and -pass in these arguments enumerated above in the signature, and no errors will -be raised because the signatures are completely compatible with each other. - -If, however, you decide to deviate from this signature and do something like this: - -.. testcode:: - - def sum(self, axis=None, dtype=None): - ... - -This object is no longer compatible with ``np.sum`` because if you call ``np.sum``, -it will pass in unexpected arguments ``out`` and ``keepdims``, causing a TypeError -to be raised. - -If you wish to maintain compatibility with numpy and its subsequent versions (which -might add new keyword arguments) but do not want to surface all of numpy's arguments, -your function's signature should accept ``**kwargs``. For example: - -.. testcode:: - - def sum(self, axis=None, dtype=None, **unused_kwargs): - ... - -This object is now compatible with ``np.sum`` again because any extraneous arguments -(i.e. keywords that are not ``axis`` or ``dtype``) will be hidden away in the -``**unused_kwargs`` parameter. - -""" -from __future__ import division, absolute_import, print_function diff --git a/venv/lib/python3.7/site-packages/numpy/doc/ufuncs.py b/venv/lib/python3.7/site-packages/numpy/doc/ufuncs.py deleted file mode 100644 index df2c455..0000000 --- a/venv/lib/python3.7/site-packages/numpy/doc/ufuncs.py +++ /dev/null @@ -1,138 +0,0 @@ -""" -=================== -Universal Functions -=================== - -Ufuncs are, generally speaking, mathematical functions or operations that are -applied element-by-element to the contents of an array. That is, the result -in each output array element only depends on the value in the corresponding -input array (or arrays) and on no other array elements. NumPy comes with a -large suite of ufuncs, and scipy extends that suite substantially. The simplest -example is the addition operator: :: - - >>> np.array([0,2,3,4]) + np.array([1,1,-1,2]) - array([1, 3, 2, 6]) - -The ufunc module lists all the available ufuncs in numpy. Documentation on -the specific ufuncs may be found in those modules. This documentation is -intended to address the more general aspects of ufuncs common to most of -them. All of the ufuncs that make use of Python operators (e.g., +, -, etc.) -have equivalent functions defined (e.g. add() for +) - -Type coercion -============= - -What happens when a binary operator (e.g., +,-,\\*,/, etc) deals with arrays of -two different types? What is the type of the result? Typically, the result is -the higher of the two types. For example: :: - - float32 + float64 -> float64 - int8 + int32 -> int32 - int16 + float32 -> float32 - float32 + complex64 -> complex64 - -There are some less obvious cases generally involving mixes of types -(e.g. uints, ints and floats) where equal bit sizes for each are not -capable of saving all the information in a different type of equivalent -bit size. Some examples are int32 vs float32 or uint32 vs int32. -Generally, the result is the higher type of larger size than both -(if available). So: :: - - int32 + float32 -> float64 - uint32 + int32 -> int64 - -Finally, the type coercion behavior when expressions involve Python -scalars is different than that seen for arrays. Since Python has a -limited number of types, combining a Python int with a dtype=np.int8 -array does not coerce to the higher type but instead, the type of the -array prevails. So the rules for Python scalars combined with arrays is -that the result will be that of the array equivalent the Python scalar -if the Python scalar is of a higher 'kind' than the array (e.g., float -vs. int), otherwise the resultant type will be that of the array. -For example: :: - - Python int + int8 -> int8 - Python float + int8 -> float64 - -ufunc methods -============= - -Binary ufuncs support 4 methods. - -**.reduce(arr)** applies the binary operator to elements of the array in - sequence. For example: :: - - >>> np.add.reduce(np.arange(10)) # adds all elements of array - 45 - -For multidimensional arrays, the first dimension is reduced by default: :: - - >>> np.add.reduce(np.arange(10).reshape(2,5)) - array([ 5, 7, 9, 11, 13]) - -The axis keyword can be used to specify different axes to reduce: :: - - >>> np.add.reduce(np.arange(10).reshape(2,5),axis=1) - array([10, 35]) - -**.accumulate(arr)** applies the binary operator and generates an an -equivalently shaped array that includes the accumulated amount for each -element of the array. A couple examples: :: - - >>> np.add.accumulate(np.arange(10)) - array([ 0, 1, 3, 6, 10, 15, 21, 28, 36, 45]) - >>> np.multiply.accumulate(np.arange(1,9)) - array([ 1, 2, 6, 24, 120, 720, 5040, 40320]) - -The behavior for multidimensional arrays is the same as for .reduce(), -as is the use of the axis keyword). - -**.reduceat(arr,indices)** allows one to apply reduce to selected parts - of an array. It is a difficult method to understand. See the documentation - at: - -**.outer(arr1,arr2)** generates an outer operation on the two arrays arr1 and - arr2. It will work on multidimensional arrays (the shape of the result is - the concatenation of the two input shapes.: :: - - >>> np.multiply.outer(np.arange(3),np.arange(4)) - array([[0, 0, 0, 0], - [0, 1, 2, 3], - [0, 2, 4, 6]]) - -Output arguments -================ - -All ufuncs accept an optional output array. The array must be of the expected -output shape. Beware that if the type of the output array is of a different -(and lower) type than the output result, the results may be silently truncated -or otherwise corrupted in the downcast to the lower type. This usage is useful -when one wants to avoid creating large temporary arrays and instead allows one -to reuse the same array memory repeatedly (at the expense of not being able to -use more convenient operator notation in expressions). Note that when the -output argument is used, the ufunc still returns a reference to the result. - - >>> x = np.arange(2) - >>> np.add(np.arange(2),np.arange(2.),x) - array([0, 2]) - >>> x - array([0, 2]) - -and & or as ufuncs -================== - -Invariably people try to use the python 'and' and 'or' as logical operators -(and quite understandably). But these operators do not behave as normal -operators since Python treats these quite differently. They cannot be -overloaded with array equivalents. Thus using 'and' or 'or' with an array -results in an error. There are two alternatives: - - 1) use the ufunc functions logical_and() and logical_or(). - 2) use the bitwise operators & and \\|. The drawback of these is that if - the arguments to these operators are not boolean arrays, the result is - likely incorrect. On the other hand, most usages of logical_and and - logical_or are with boolean arrays. As long as one is careful, this is - a convenient way to apply these operators. - -""" -from __future__ import division, absolute_import, print_function diff --git a/venv/lib/python3.7/site-packages/numpy/dual.py b/venv/lib/python3.7/site-packages/numpy/dual.py deleted file mode 100644 index 651e845..0000000 --- a/venv/lib/python3.7/site-packages/numpy/dual.py +++ /dev/null @@ -1,71 +0,0 @@ -""" -Aliases for functions which may be accelerated by Scipy. - -Scipy_ can be built to use accelerated or otherwise improved libraries -for FFTs, linear algebra, and special functions.

When both the function and its Fourier transform are -replaced with discretized counterparts, it is called the discrete Fourier -transform (DFT). The DFT has become a mainstay of numerical computing in -part because of a very fast algorithm for computing it, called the Fast -Fourier Transform (FFT), which was known to Gauss (1805) and was brought -to light in its current form by Cooley and Tukey [CT]_. Press et al. [NR]_ -provide an accessible introduction to Fourier analysis and its -applications. - -Because the discrete Fourier transform separates its input into -components that contribute at discrete frequencies, it has a great number -of applications in digital signal processing, e.g., for filtering, and in -this context the discretized input to the transform is customarily -referred to as a *signal*, which exists in the *time domain*. The output -is called a *spectrum* or *transform* and exists in the *frequency -domain*. - -Implementation details ----------------------- - -There are many ways to define the DFT, varying in the sign of the -exponent, normalization, etc. In this implementation, the DFT is defined -as - -.. math:: - A_k = \\sum_{m=0}^{n-1} a_m \\exp\\left\\{-2\\pi i{mk \\over n}\\right\\} - \\qquad k = 0,\\ldots,n-1. - -The DFT is in general defined for complex inputs and outputs, and a -single-frequency component at linear frequency :math:`f` is -represented by a complex exponential -:math:`a_m = \\exp\\{2\\pi i\\,f m\\Delta t\\}`, where :math:`\\Delta t` -is the sampling interval. - -The values in the result follow so-called "standard" order: If ``A = -fft(a, n)``, then ``A[0]`` contains the zero-frequency term (the sum of -the signal), which is always purely real for real inputs. Then ``A[1:n/2]`` -contains the positive-frequency terms, and ``A[n/2+1:]`` contains the -negative-frequency terms, in order of decreasingly negative frequency. -For an even number of input points, ``A[n/2]`` represents both positive and -negative Nyquist frequency, and is also purely real for real input. For -an odd number of input points, ``A[(n-1)/2]`` contains the largest positive -frequency, while ``A[(n+1)/2]`` contains the largest negative frequency. -The routine ``np.fft.fftfreq(n)`` returns an array giving the frequencies -of corresponding elements in the output. The routine -``np.fft.fftshift(A)`` shifts transforms and their frequencies to put the -zero-frequency components in the middle, and ``np.fft.ifftshift(A)`` undoes -that shift. - -When the input `a` is a time-domain signal and ``A = fft(a)``, ``np.abs(A)`` -is its amplitude spectrum and ``np.abs(A)**2`` is its power spectrum. -The phase spectrum is obtained by ``np.angle(A)``. - -The inverse DFT is defined as - -.. math:: - a_m = \\frac{1}{n}\\sum_{k=0}^{n-1}A_k\\exp\\left\\{2\\pi i{mk\\over n}\\right\\} - \\qquad m = 0,\\ldots,n-1. - -It differs from the forward transform by the sign of the exponential -argument and the default normalization by :math:`1/n`. - -Type Promotion --------------- - -`numpy.fft` promotes ``float32`` and ``complex64`` arrays to ``float64`` and -``complex128`` arrays respectively. For an FFT implementation that does not -promote input arrays, see `scipy.fftpack`. - -Normalization -------------- - -The default normalization has the direct transforms unscaled and the inverse -transforms are scaled by :math:`1/n`. It is possible to obtain unitary -transforms by setting the keyword argument ``norm`` to ``"ortho"`` (default is -`None`) so that both direct and inverse transforms will be scaled by -:math:`1/\\sqrt{n}`. - -Real and Hermitian transforms ------------------------------ - -When the input is purely real, its transform is Hermitian, i.e., the -component at frequency :math:`f_k` is the complex conjugate of the -component at frequency :math:`-f_k`, which means that for real -inputs there is no information in the negative frequency components that -is not already available from the positive frequency components. -The family of `rfft` functions is -designed to operate on real inputs, and exploits this symmetry by -computing only the positive frequency components, up to and including the -Nyquist frequency. Thus, ``n`` input points produce ``n/2+1`` complex -output points. The inverses of this family assumes the same symmetry of -its input, and for an output of ``n`` points uses ``n/2+1`` input points. - -Correspondingly, when the spectrum is purely real, the signal is -Hermitian. The `hfft` family of functions exploits this symmetry by -using ``n/2+1`` complex points in the input (time) domain for ``n`` real -points in the frequency domain. - -In higher dimensions, FFTs are used, e.g., for image analysis and -filtering. The computational efficiency of the FFT means that it can -also be a faster way to compute large convolutions, using the property -that a convolution in the time domain is equivalent to a point-by-point -multiplication in the frequency domain. - -Higher dimensions ------------------ - -In two dimensions, the DFT is defined as - -.. math:: - A_{kl} = \\sum_{m=0}^{M-1} \\sum_{n=0}^{N-1} - a_{mn}\\exp\\left\\{-2\\pi i \\left({mk\\over M}+{nl\\over N}\\right)\\right\\} - \\qquad k = 0, \\ldots, M-1;\\quad l = 0, \\ldots, N-1, - -which extends in the obvious way to higher dimensions, and the inverses -in higher dimensions also extend in the same way. - -References ----------- - -..

The format stores all -of the shape and dtype information necessary to reconstruct the array -correctly even on another machine with a different architecture. -The format is designed to be as simple as possible while achieving -its limited goals. - -The ``.npz`` format is the standard format for persisting *multiple* NumPy -arrays on disk. A ``.npz`` file is a zip file containing multiple ``.npy`` -files, one for each array. - -Capabilities ------------- - -- Can represent all NumPy arrays including nested record arrays and - object arrays. - -- Represents the data in its native binary form. - -- Supports Fortran-contiguous arrays directly. - -- Stores all of the necessary information to reconstruct the array - including shape and dtype on a machine of a different - architecture. Both little-endian and big-endian arrays are - supported, and a file with little-endian numbers will yield - a little-endian array on any machine reading the file. The - types are described in terms of their actual sizes. For example, - if a machine with a 64-bit C "long int" writes out an array with - "long ints", a reading machine with 32-bit C "long ints" will yield - an array with 64-bit integers. - -- Is straightforward to reverse engineer. Datasets often live longer than - the programs that created them. A competent developer should be - able to create a solution in their preferred programming language to - read most ``.npy`` files that he has been given without much - documentation. - -- Allows memory-mapping of the data. See `open_memmep`. - -- Can be read from a filelike stream object instead of an actual file. - -- Stores object arrays, i.e. arrays containing elements that are arbitrary - Python objects. Files with object arrays are not to be mmapable, but - can be read and written to disk. - -Limitations ------------ - -- Arbitrary subclasses of numpy.ndarray are not completely preserved. - Subclasses will be accepted for writing, but only the array data will - be written out. A regular numpy.ndarray object will be created - upon reading the file. - -.. warning:: - - Due to limitations in the interpretation of structured dtypes, dtypes - with fields with empty names will have the names replaced by 'f0', 'f1', - etc. Such arrays will not round-trip through the format entirely - accurately. The data is intact; only the field names will differ. We are - working on a fix for this. This fix will not require a change in the - file format. The arrays with such structures can still be saved and - restored, and the correct dtype may be restored by using the - ``loadedarray.view(correct_dtype)`` method. - -File extensions ---------------- - -We recommend using the ``.npy`` and ``.npz`` extensions for files saved -in this format. This is by no means a requirement; applications may wish -to use these file formats but use an extension specific to the -application. In the absence of an obvious alternative, however, -we suggest using ``.npy`` and ``.npz``. - -Version numbering ------------------ - -The version numbering of these formats is independent of NumPy version -numbering. If the format is upgraded, the code in `numpy.io` will still -be able to read and write Version 1.0 files. - -Format Version 1.0 ------------------- - -The first 6 bytes are a magic string: exactly ``\\x93NUMPY``. - -The next 1 byte is an unsigned byte: the major version number of the file -format, e.g. ``\\x01``. - -The next 1 byte is an unsigned byte: the minor version number of the file -format, e.g. ``\\x00``. Note: the version of the file format is not tied -to the version of the numpy package. - -The next 2 bytes form a little-endian unsigned short int: the length of -the header data HEADER_LEN. - -The next HEADER_LEN bytes form the header data describing the array's -format. It is an ASCII string which contains a Python literal expression -of a dictionary. It is terminated by a newline (``\\n``) and padded with -spaces (``\\x20``) to make the total of -``len(magic string) + 2 + len(length) + HEADER_LEN`` be evenly divisible -by 64 for alignment purposes. - -The dictionary contains three keys: - - "descr" : dtype.descr - An object that can be passed as an argument to the `numpy.dtype` - constructor to create the array's dtype. - "fortran_order" : bool - Whether the array data is Fortran-contiguous or not. Since - Fortran-contiguous arrays are a common form of non-C-contiguity, - we allow them to be written directly to disk for efficiency. - "shape" : tuple of int - The shape of the array. - -For repeatability and readability, the dictionary keys are sorted in -alphabetic order. This is for convenience only. A writer SHOULD implement -this if possible. A reader MUST NOT depend on this. - -Following the header comes the array data. If the dtype contains Python -objects (i.e. ``dtype.hasobject is True``), then the data is a Python -pickle of the array. Otherwise the data is the contiguous (either C- -or Fortran-, depending on ``fortran_order``) bytes of the array. -Consumers can figure out the number of bytes by multiplying the number -of elements given by the shape (noting that ``shape=()`` means there is -1 element) by ``dtype.itemsize``. - -Format Version 2.0 ------------------- - -The version 1.0 format only allowed the array header to have a total size of -65535 bytes.

Note that having the number of bins - proportional to :math:`n^{1/3}` is asymptotically optimal, which is - why it appears in most estimators. These are simply plug-in methods - that give good starting points for number of bins. In the equations - below, :math:`h` is the binwidth and :math:`n_h` is the number of - bins. All estimators that compute bin counts are recast to bin width - using the `ptp` of the data. The final bin count is obtained from - ``np.round(np.ceil(range / h))``. - - 'auto' (maximum of the 'sturges' and 'fd' estimators) - A compromise to get a good value. For small datasets the Sturges - value will usually be chosen, while larger datasets will usually - default to FD. Avoids the overly conservative behaviour of FD - and Sturges for small and large datasets respectively. - Switchover point is usually :math:`a.size \approx 1000`. - - 'fd' (Freedman Diaconis Estimator) - .. math:: h = 2 \frac{IQR}{n^{1/3}} - - The binwidth is proportional to the interquartile range (IQR) - and inversely proportional to cube root of a.size. Can be too - conservative for small datasets, but is quite good for large - datasets. The IQR is very robust to outliers. - - 'scott' - .. math:: h = \sigma \sqrt[3]{\frac{24 * \sqrt{\pi}}{n}} - - The binwidth is proportional to the standard deviation of the - data and inversely proportional to cube root of ``x.size``. Can - be too conservative for small datasets, but is quite good for - large datasets. The standard deviation is not very robust to - outliers. Values are very similar to the Freedman-Diaconis - estimator in the absence of outliers. - - 'rice' - .. math:: n_h = 2n^{1/3} - - The number of bins is only proportional to cube root of - ``a.size``. It tends to overestimate the number of bins and it - does not take into account data variability. - - 'sturges' - .. math:: n_h = \log _{2}n+1 - - The number of bins is the base 2 log of ``a.size``. This - estimator assumes normality of data and is too conservative for - larger, non-normal datasets.

It also - appears in *Numerical recipes* in the discussion of SVD solutions for linear - least squares [2]. - - This default threshold is designed to detect rank deficiency accounting for - the numerical errors of the SVD computation. Imagine that there is a column - in `M` that is an exact (in floating point) linear combination of other - columns in `M`. Computing the SVD on `M` will not produce a singular value - exactly equal to 0 in general: any difference of the smallest SVD value from - 0 will be caused by numerical imprecision in the calculation of the SVD. - Our threshold for small SVD values takes this numerical imprecision into - account, and the default threshold will detect such numerical rank - deficiency. The threshold may declare a matrix `M` rank deficient even if - the linear combination of some columns of `M` is not exactly equal to - another column of `M` but only numerically very close to another column of - `M`. - - We chose our default threshold because it is in wide use. Other thresholds - are possible. For example, elsewhere in the 2007 edition of *Numerical - recipes* there is an alternative threshold of ``S.max() * - np.finfo(M.dtype).eps / 2. * np.sqrt(m + n + 1.)``. The authors describe - this threshold as being based on "expected roundoff error" (p 71). - - The thresholds above deal with floating point roundoff error in the - calculation of the SVD. However, you may have more information about the - sources of error in `M` that would make you consider other tolerance values - to detect *effective* rank deficiency. The most useful measure of the - tolerance depends on the operations you intend to use on your matrix. For - example, if your data come from uncertain measurements with uncertainties - greater than floating point epsilon, choosing a tolerance near that - uncertainty may be preferable. The tolerance may be absolute if the - uncertainties are absolute rather than relative. - - References - ---------- - ..

Logical Hebrew ?? -# -# Both "ISO" charsets use a completely identical set of code points, whereas -# "windows-1255" and "x-mac-hebrew" are two different proper supersets of -# these code points. windows-1255 defines additional characters in the range -# 0x80-0x9F as some misc punctuation marks as well as some Hebrew-specific -# diacritics and additional 'Yiddish' ligature letters in the range 0xc0-0xd6. -# x-mac-hebrew defines similar additional code points but with a different -# mapping. -# -# As far as an average Hebrew text with no diacritics is concerned, all four -# charsets are identical with respect to code points. Meaning that for the -# main Hebrew alphabet, all four map the same values to all 27 Hebrew letters -# (including final letters). -# -# The dominant difference between these charsets is their directionality. -# "Visual" directionality means that the text is ordered as if the renderer is -# not aware of a BIDI rendering algorithm. The renderer sees the text and -# draws it from left to right. The text itself when ordered naturally is read -# backwards. A buffer of Visual Hebrew generally looks like so: -# "[last word of first line spelled backwards] [whole line ordered backwards -# and spelled backwards] [first word of first line spelled backwards] -# [end of line] [last word of second line] ... etc' " -# adding punctuation marks, numbers and English text to visual text is -# naturally also "visual" and from left to right. -# -# "Logical" directionality means the text is ordered "naturally" according to -# the order it is read. It is the responsibility of the renderer to display -# the text from right to left. A BIDI algorithm is used to place general -# punctuation marks, numbers and English text in the text. -# -# Texts in x-mac-hebrew are almost impossible to find on the Internet. From -# what little evidence I could find, it seems that its general directionality -# is Logical. -# -# To sum up all of the above, the Hebrew probing mechanism knows about two -# charsets: -# Visual Hebrew - "ISO-8859-8" - backwards text - Words and sentences are -# backwards while line order is natural. For charset recognition purposes -# the line order is unimportant (In fact, for this implementation, even -# word order is unimportant). -# Logical Hebrew - "windows-1255" - normal, naturally ordered text. -# -# "ISO-8859-8-I" is a subset of windows-1255 and doesn't need to be -# specifically identified. -# "x-mac-hebrew" is also identified as windows-1255. A text in x-mac-hebrew -# that contain special punctuation marks or diacritics is displayed with -# some unconverted characters showing as question marks. This problem might -# be corrected using another model prober for x-mac-hebrew. Due to the fact -# that x-mac-hebrew texts are so rare, writing another model prober isn't -# worth the effort and performance hit. -# -#### The Prober #### -# -# The prober is divided between two SBCharSetProbers and a HebrewProber, -# all of which are managed, created, fed data, inquired and deleted by the -# SBCSGroupProber. The two SBCharSetProbers identify that the text is in -# fact some kind of Hebrew, Logical or Visual. The final decision about which -# one is it is made by the HebrewProber by combining final-letter scores -# with the scores of the two SBCharSetProbers to produce a final answer. -# -# The SBCSGroupProber is responsible for stripping the original text of HTML -# tags, English characters, numbers, low-ASCII punctuation characters, spaces -# and new lines. It reduces any sequence of such characters to a single space. -# The buffer fed to each prober in the SBCS group prober is pure text in -# high-ASCII. -# The two SBCharSetProbers (model probers) share the same language model: -# Win1255Model. -# The first SBCharSetProber uses the model normally as any other -# SBCharSetProber does, to recognize windows-1255, upon which this model was -# built. The second SBCharSetProber is told to make the pair-of-letter -# lookup in the language model backwards. This in practice exactly simulates -# a visual Hebrew model using the windows-1255 logical Hebrew model. -# -# The HebrewProber is not using any language model. All it does is look for -# final-letter evidence suggesting the text is either logical Hebrew or visual -# Hebrew. Disjointed from the model probers, the results of the HebrewProber -# alone are meaningless. HebrewProber always returns 0.00 as confidence -# since it never identifies a charset by itself. Instead, the pointer to the -# HebrewProber is passed to the model probers as a helper "Name Prober". -# When the Group prober receives a positive identification from any prober, -# it asks for the name of the charset identified.

There -are the main Sprite class and several Group classes that contain Sprites. -The use of these classes is entirely optional when using Pygame. The classes -are fairly lightweight and only provide a starting place for the code -that is common to most games. - -The Sprite class is intended to be used as a base class for the different -types of objects in the game. There is also a base Group class that simply -stores sprites. A game could create new types of Group classes that operate -on specially customized Sprite instances they contain. - -The basic Sprite class can draw the Sprites it contains to a Surface. The -Group.draw() method requires that each Sprite have a Surface.image attribute -and a Surface.rect. The Group.clear() method requires these same attributes -and can be used to erase all the Sprites with background. There are also -more advanced Groups: pygame.sprite.RenderUpdates() and -pygame.sprite.OrderedUpdates(). - -Lastly, this module contains several collision functions. These help find -sprites inside multiple groups that have intersecting bounding rectangles. -To find the collisions, the Sprites are required to have a Surface.rect -attribute assigned. - -The groups are designed for high efficiency in removing and adding Sprites -to them. They also allow cheap testing to see if a Sprite already exists in -a Group. A given Sprite can exist in any number of groups. A game could use -some groups to control object rendering, and a completely separate set of -groups to control interaction or player movement. Instead of adding type -attributes or bools to a derived Sprite class, consider keeping the -Sprites inside organized Groups. This will allow for easier lookup later -in the game. - -Sprites and Groups manage their relationships with the add() and remove() -methods. These methods can accept a single or multiple group arguments for -membership. The default initializers for these classes also take a -single group or list of groups as argments for initial membership. It is safe -to repeatedly add and remove the same Sprite from a Group. - -While it is possible to design sprite and group classes that don't derive -from the Sprite and AbstractGroup classes below, it is strongly recommended -that you extend those when you create a new Sprite or Group class. - -Sprites are not thread safe, so lock them yourself if using threads. - -""" - -##todo -## a group that holds only the 'n' most recent elements. -## sort of like the GroupSingle class, but holding more -## than one sprite -## -## drawing groups that can 'automatically' store the area -## underneath so they can "clear" without needing a background -## function. obviously a little slower than normal, but nice -## to use in many situations.

It reads -and writes PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 -bits per pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, -RGBA, LA (greyscale with alpha) with 8/16 bits per channel; colour mapped -images (1/2/4/8 bit). Adam7 interlacing is supported for reading and -writing. A number of optional chunks can be specified (when writing) -and understood (when reading): ``tRNS``, ``bKGD``, ``gAMA``. - -For help, type ``import png; help(png)`` in your python interpreter. - -A good place to start is the :class:`Reader` and :class:`Writer` classes. - -This file can also be used as a command-line utility to convert -`Netpbm `_ PNM files to PNG, and the reverse conversion from PNG to -PNM. The interface is similar to that of the ``pnmtopng`` program from -Netpbm. Type ``python png.py --help`` at the shell prompt -for usage and a list of options. - -A note on spelling and terminology ----------------------------------- - -Generally British English spelling is used in the documentation. So -that's "greyscale" and "colour". This not only matches the author's -native language, it's also used by the PNG specification. - -The major colour models supported by PNG (and hence by PyPNG) are: -greyscale, RGB, greyscale--alpha, RGB--alpha. These are sometimes -referred to using the abbreviations: L, RGB, LA, RGBA. In this case -each letter abbreviates a single channel: *L* is for Luminance or Luma or -Lightness which is the channel used in greyscale images; *R*, *G*, *B* stand -for Red, Green, Blue, the components of a colour image; *A* stands for -Alpha, the opacity channel (used for transparency effects, but higher -values are more opaque, so it makes sense to call it opacity). - -A note on formats ------------------ - -When getting pixel data out of this module (reading) and presenting -data to this module (writing) there are a number of ways the data could -be represented as a Python value. Generally this module uses one of -three formats called "flat row flat pixel", "boxed row flat pixel", and -"boxed row boxed pixel". Basically the concern is whether each pixel -and each row comes in its own little tuple (box), or not. - -Consider an image that is 3 pixels wide by 2 pixels high, and each pixel -has RGB components: - -Boxed row flat pixel:: - - list([R,G,B, R,G,B, R,G,B], - [R,G,B, R,G,B, R,G,B]) - -Each row appears as its own list, but the pixels are flattened so that -three values for one pixel simply follow the three values for the previous -pixel. This is the most common format used, because it provides a good -compromise between space and convenience. PyPNG regards itself as -at liberty to replace any sequence type with any sufficiently compatible -other sequence type; in practice each row is an array (from the array -module), and the outer list is sometimes an iterator rather than an -explicit list (so that streaming is possible). - -Flat row flat pixel:: - - [R,G,B, R,G,B, R,G,B, - R,G,B, R,G,B, R,G,B] - -The entire image is one single giant sequence of colour values. -Generally an array will be used (to save space), not a list. - -Boxed row boxed pixel:: - - list([ (R,G,B), (R,G,B), (R,G,B) ], - [ (R,G,B), (R,G,B), (R,G,B) ]) - -Each row appears in its own list, but each pixel also appears in its own -tuple. A serious memory burn in Python. - -In all cases the top row comes first, and for each row the pixels are -ordered from left-to-right. Within a pixel the values appear in the -order, R-G-B-A (or L-A for greyscale--alpha). - -There is a fourth format, mentioned because it is used internally, -is close to what lies inside a PNG file itself, and has some support -from the public API. This format is called packed. When packed, -each row is a sequence of bytes (integers from 0 to 255), just as -it is before PNG scanline filtering is applied. When the bit depth -is 8 this is essentially the same as boxed row flat pixel; when the -bit depth is less than 8, several pixels are packed into each byte; -when the bit depth is 16 (the only value more than 8 that is supported -by the PNG image format) each pixel value is decomposed into 2 bytes -(and `packed` is a misnomer). This format is used by the -:meth:`Writer.write_packed` method. It isn't usually a convenient -format, but may be just right if the source data for the PNG image -comes from something that uses a similar format (for example, 1-bit -BMPs, or another PNG file). - -And now, my famous members --------------------------- -""" - -__version__ = "$URL: http://pypng.googlecode.com/svn/trunk/code/png.py $ $Rev: 228 $" - -from pygame.compat import geterror, imap_ -from array import array -import itertools -import math -import operator -import struct -import sys -import zlib -import warnings - - -__all__ = ['Image', 'Reader', 'Writer', 'write_chunks', 'from_array'] - - -# The PNG signature. -# http://www.w3.org/TR/PNG/#5PNG-file-signature -_signature = struct.pack('8B', 137, 80, 78, 71, 13, 10, 26, 10) - -_adam7 = ((0, 0, 8, 8), - (4, 0, 8, 8), - (0, 4, 4, 8), - (2, 0, 4, 4), - (0, 2, 2, 4), - (1, 0, 2, 2), - (0, 1, 1, 2)) - -def group(s, n): - # See - # http://www.python.org/doc/2.6/library/functions.html#zip - return zip(*[iter(s)]*n) - -def isarray(x): - """Same as ``isinstance(x, array)``. - """ - return isinstance(x, array) - - -def tostring(row): - """Convert row of bytes to string.

If `size` is used it should be a pair (*width*, - *height*). - - `greyscale` and `alpha` are booleans that specify whether - an image is greyscale (or colour), and whether it has an - alpha channel (or not). - - `bitdepth` specifies the bit depth of the source pixel values. - Each source pixel value must be an integer between 0 and - ``2**bitdepth-1``. For example, 8-bit images have values - between 0 and 255. PNG only stores images with bit depths of - 1,2,4,8, or 16. When `bitdepth` is not one of these values, - the next highest valid bit depth is selected, and an ``sBIT`` - (significant bits) chunk is generated that specifies the original - precision of the source image. In this case the supplied pixel - values will be rescaled to fit the range of the selected bit depth. - - The details of which bit depth / colour model combinations the - PNG file format supports directly, are somewhat arcane - (refer to the PNG specification for full details). Briefly: - "small" bit depths (1,2,4) are only allowed with greyscale and - colour mapped images; colour mapped images cannot have bit depth - 16. - - For colour mapped images (in other words, when the `palette` - argument is specified) the `bitdepth` argument must match one of - the valid PNG bit depths: 1, 2, 4, or 8. (It is valid to have a - PNG image with a palette and an ``sBIT`` chunk, but the meaning - is slightly different; it would be awkward to press the - `bitdepth` argument into service for this.) - - The `palette` option, when specified, causes a colour mapped image - to be created: the PNG colour type is set to 3; greyscale - must not be set; alpha must not be set; transparent must - not be set; the bit depth must be 1,2,4, or 8. When a colour - mapped image is created, the pixel values are palette indexes - and the `bitdepth` argument specifies the size of these indexes - (not the size of the colour values in the palette). - - The palette argument value should be a sequence of 3- or - 4-tuples. 3-tuples specify RGB palette entries; 4-tuples - specify RGBA palette entries. If both 4-tuples and 3-tuples - appear in the sequence then all the 4-tuples must come - before all the 3-tuples. A ``PLTE`` chunk is created; if there - are 4-tuples then a ``tRNS`` chunk is created as well. The - ``PLTE`` chunk will contain all the RGB triples in the same - sequence; the ``tRNS`` chunk will contain the alpha channel for - all the 4-tuples, in the same sequence. Palette entries - are always 8-bit. - - If specified, the `transparent` and `background` parameters must - be a tuple with three integer values for red, green, blue, or - a simple integer (or singleton tuple) for a greyscale image. - - If specified, the `gamma` parameter must be a positive number - (generally, a float). A ``gAMA`` chunk will be created. Note that - this will not change the values of the pixels as they appear in - the PNG file, they are assumed to have already been converted - appropriately for the gamma specified. - - The `compression` argument specifies the compression level - to be used by the ``zlib`` module. Higher values are likely - to compress better, but will be slower to compress. The - default for this argument is ``None``; this does not mean - no compression, rather it means that the default from the - ``zlib`` module is used (which is generally acceptable). - - If `interlace` is true then an interlaced image is created - (using PNG's so far only interace method, *Adam7*). This does not - affect how the pixels should be presented to the encoder, rather - it changes how they are arranged into the PNG file. On slow - connexions interlaced images can be partially decoded by the - browser to give a rough view of the image that is successively - refined as more image data appears. - - .. note :: - - Enabling the `interlace` option requires the entire image - to be processed in working memory. - - `chunk_limit` is used to limit the amount of memory used whilst - compressing the image.

It can be: - - ``'L'`` - greyscale (1 channel) - ``'LA'`` - greyscale with alpha (2 channel) - ``'RGB'`` - colour image (3 channel) - ``'RGBA'`` - colour image with alpha (4 channel) - - The mode string can also specify the bit depth (overriding how this - function normally derives the bit depth, see below). Appending - ``';16'`` to the mode will cause the PNG to be 16 bits per channel; - any decimal from 1 to 16 can be used to specify the bit depth. - - When a 2-dimensional array is used *mode* determines how many - channels the image has, and so allows the width to be derived from - the second array dimension. - - The array is expected to be a ``numpy`` array, but it can be any - suitable Python sequence. For example, a list of lists can be used: - ``png.from_array([[0, 255, 0], [255, 0, 255]], 'L')``. The exact - rules are: ``len(a)`` gives the first dimension, height; - ``len(a[0])`` gives the second dimension; ``len(a[0][0])`` gives the - third dimension, unless an exception is raised in which case a - 2-dimensional array is assumed. It's slightly more complicated than - that because an iterator of rows can be used, and it all still - works. Using an iterator allows data to be streamed efficiently. - - The bit depth of the PNG is normally taken from the array element's - datatype (but if *mode* specifies a bitdepth then that is used - instead). The array element's datatype is determined in a way which - is supposed to work both for ``numpy`` arrays and for Python - ``array.array`` objects. A 1 byte datatype will give a bit depth of - 8, a 2 byte datatype will give a bit depth of 16. If the datatype - does not have an implicit size, for example it is a plain Python - list of lists, as above, then a default of 8 is used. - - The *info* parameter is a dictionary that can be used to specify - metadata (in the same style as the arguments to the - :class:``png.Writer`` class). For this function the keys that are - useful are: - - height - overrides the height derived from the array dimensions and allows - *a* to be an iterable. - width - overrides the width derived from the array dimensions. - bitdepth - overrides the bit depth derived from the element datatype (but - must match *mode* if that also specifies a bit depth). - - Generally anything specified in the - *info* dictionary will override any implicit choices that this - function would otherwise make, but must match any explicit ones. - For example, if the *info* dictionary has a ``greyscale`` key then - this must be true when mode is ``'L'`` or ``'LA'`` and false when - mode is ``'RGB'`` or ``'RGBA'``. - """ - - # We abuse the *info* parameter by modifying it.
