r"""Multiplies slices of two tensors in batches.
Multiplies all slices of `Tensor` `x` and `y` (each slice can be
viewed as an element of a batch), and arranges the individual results
in a single output tensor of the same batch size. Each of the
individual slices can optionally be adjointed (to adjoint a matrix
means to transpose and conjugate it) before multiplication by setting
the `adj_x` or `adj_y` flag to `True`, which are by default `False`.
The input tensors `x` and `y` are 2-D or higher with shape `[..., r_x, c_x]`
and `[..., r_y, c_y]`.
The output tensor is 2-D or higher with shape `[..., r_o, c_o]`, where:
r_o = c_x if adj_x else r_x
c_o = r_y if adj_y else c_y
It is computed as:
output[..., :, :] = matrix(x[..., :, :]) * matrix(y[..., :, :])
*NOTE*: `BatchMatMulV3` supports broadcasting in the batch dimensions. More
about broadcasting
[here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html).
Args:
x: A `Tensor`. Must be one of the following types: `bfloat16`, `half`, `float32`, `float64`, `uint8`, `int8`, `int16`, `int32`, `int64`, `complex64`, `complex128`.
2-D or higher with shape `[..., r_x, c_x]`.
y: A `Tensor`. Must be one of the following types: `bfloat16`, `half`, `float32`, `float64`, `uint8`, `int8`, `int16`, `int32`, `int64`, `complex64`, `complex128`.
2-D or higher with shape `[..., r_y, c_y]`.
Tout: A `tf.DType` from: `tf.bfloat16, tf.half, tf.float32, tf.float64, tf.int16, tf.int32, tf.int64, tf.complex64, tf.complex128`.
If not spcified, Tout is the same type to input type.
adj_x: An optional `bool`. Defaults to `False`.
If `True`, adjoint the slices of `x`. Defaults to `False`.
adj_y: An optional `bool`. Defaults to `False`.
If `True`, adjoint the slices of `y`. Defaults to `False`.
grad_x: An optional `bool`. Defaults to `False`.
grad_y: An optional `bool`. Defaults to `False`.
name: A name for the operation (optional).
Returns:
A `Tensor` of type `Tout`.

r"""Returns the truth value of x AND y element-wise.
Logical AND function.
Requires that `x` and `y` have the same shape or have
[broadcast-compatible](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)
shapes. For example, `x` and `y` can be:
- Two single elements of type `bool`.
- One `tf.Tensor` of type `bool` and one single `bool`, where the result will
be calculated by applying logical AND with the single element to each
element in the larger Tensor.
- Two `tf.Tensor` objects of type `bool` of the same shape. In this case,
the result will be the element-wise logical AND of the two input tensors.
You can also use the `&` operator instead.
Usage:
>>> a = tf.constant([True])
>>> b = tf.constant([False])
>>> tf.math.logical_and(a, b)
<tf.Tensor: shape=(1,), dtype=bool, numpy=array([False])>
>>> a & b
<tf.Tensor: shape=(1,), dtype=bool, numpy=array([False])>
>>> c = tf.constant([True])
>>> x = tf.constant([False, True, True, False])
>>> tf.math.logical_and(c, x)
<tf.Tensor: shape=(4,), dtype=bool, numpy=array([False, True, True, False])>
>>> c & x
<tf.Tensor: shape=(4,), dtype=bool, numpy=array([False, True, True, False])>
>>> y = tf.constant([False, False, True, True])
>>> z = tf.constant([False, True, False, True])
>>> tf.math.logical_and(y, z)
<tf.Tensor: shape=(4,), dtype=bool, numpy=array([False, False, False, True])>
>>> y & z
<tf.Tensor: shape=(4,), dtype=bool, numpy=array([False, False, False, True])>
This op also supports broadcasting
>>> tf.logical_and([[True, False]], [[True], [False]])
<tf.Tensor: shape=(2, 2), dtype=bool, numpy=
array([[ True, False],

The reduction version of this elementwise operation is `tf.math.reduce_all`.
Args:
x: A `tf.Tensor` of type bool.
y: A `tf.Tensor` of type bool.
name: A name for the operation (optional).
Returns:
A `tf.Tensor` of type bool with the shape that `x` and `y` broadcast to.

r"""Convert the quantized 'input' tensor into a lower-precision 'output', using the
actual distribution of the values to maximize the usage of the lower bit depth
and adjusting the output min and max ranges accordingly.
[input_min, input_max] are scalar floats that specify the range for the float
interpretation of the 'input' data. For example, if input_min is -1.0f and
input_max is 1.0f, and we are dealing with quint16 quantized data, then a 0
value in the 16-bit data should be interpreted as -1.0f, and a 65535 means 1.0f.
This operator tries to squeeze as much precision as possible into an output with
a lower bit depth by calculating the actual min and max values found in the
data. For example, maybe that quint16 input has no values lower than 16,384 and
none higher than 49,152. That means only half the range is actually needed, all
the float interpretations are between -0.5f and 0.5f, so if we want to compress
the data into a quint8 output, we can use that range rather than the theoretical
-1.0f to 1.0f that is suggested by the input min and max.
In practice, this is most useful for taking output from operations like
QuantizedMatMul that can produce higher bit-depth outputs than their inputs and
may have large potential output ranges, but in practice have a distribution of
input values that only uses a small fraction of the possible range. By feeding
that output into this operator, we can reduce it from 32 bits down to 8 with
minimal loss of accuracy.
Args:
input: A `Tensor`. Must be one of the following types: `qint8`, `quint8`, `qint32`, `qint16`, `quint16`.
input_min: A `Tensor` of type `float32`.
The float value that the minimum quantized input value represents.
input_max: A `Tensor` of type `float32`.
The float value that the maximum quantized input value represents.
out_type: A `tf.DType` from: `tf.qint8, tf.quint8, tf.qint32, tf.qint16, tf.quint16`.
The type of the output. Should be a lower bit depth than Tinput.
name: A name for the operation (optional).
Returns:
A tuple of `Tensor` objects (output, output_min, output_max).
output: A `Tensor` of type `out_type`.
output_min: A `Tensor` of type `float32`.
output_max: A `Tensor` of type `float32`.

r"""Converts the quantized `input` tensor into a lower-precision `output`.
Converts the quantized `input` tensor into a lower-precision `output`, using the
output range specified with `requested_output_min` and `requested_output_max`.
`[input_min, input_max]` are scalar floats that specify the range for the float
interpretation of the `input` data. For example, if `input_min` is -1.0f and
`input_max` is 1.0f, and we are dealing with `quint16` quantized data, then a 0
value in the 16-bit data should be interpreted as -1.0f, and a 65535 means 1.0f.
Args:
input: A `Tensor`. Must be one of the following types: `qint8`, `quint8`, `qint32`, `qint16`, `quint16`.
input_min: A `Tensor` of type `float32`.
The float value that the minimum quantized input value represents.
input_max: A `Tensor` of type `float32`.
The float value that the maximum quantized input value represents.
requested_output_min: A `Tensor` of type `float32`.
The float value that the minimum quantized output value represents.
requested_output_max: A `Tensor` of type `float32`.
The float value that the maximum quantized output value represents.
out_type: A `tf.DType` from: `tf.qint8, tf.quint8, tf.qint32, tf.qint16, tf.quint16`.
The type of the output. Should be a lower bit depth than Tinput.
name: A name for the operation (optional).
Returns:
A tuple of `Tensor` objects (output, output_min, output_max).
output: A `Tensor` of type `out_type`.
output_min: A `Tensor` of type `float32`.
output_max: A `Tensor` of type `float32`.

If the max is empty for a given segment ID `i`, `output[i] = 0`.
Caution: On CPU, values in `segment_ids` are always validated to be sorted,
and an error is thrown for indices that are not increasing. On GPU, this
does not throw an error for unsorted indices. On GPU, out-of-order indices
result in safe but unspecified behavior, which may include treating

r"""Computes the maximum along segments of a tensor.
Read
[the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation)
for an explanation of segments.
Computes a tensor such that
\\(output_i = \max_j(data_j)\\) where `max` is over `j` such
that `segment_ids[j] == i`.
If the maximum is empty for a given segment ID `i`, it outputs the smallest
possible value for the specific numeric type,
`output[i] = numeric_limits<T>::lowest()`.
Note: That this op is currently only supported with jit_compile=True.
Caution: On CPU, values in `segment_ids` are always validated to be sorted,
and an error is thrown for indices that are not increasing. On GPU, this
does not throw an error for unsorted indices. On GPU, out-of-order indices
result in safe but unspecified behavior, which may include treating
out-of-order indices as the same as a smaller following index.
The only difference with SegmentMax is the additional input `num_segments`.
This helps in evaluating the output shape in compile time.
`num_segments` should be consistent with segment_ids.
e.g. Max(segment_ids) should be equal to `num_segments` - 1 for a 1-d segment_ids
With inconsistent num_segments, the op still runs. only difference is,
the output takes the size of num_segments irrespective of size of segment_ids and data.
for num_segments less than expected output size, the last elements are ignored
for num_segments more than the expected output size, last elements are assigned
smallest possible value for the specific numeric type.
For example:
>>> @tf.function(jit_compile=True)
... def test(c):
... return tf.raw_ops.SegmentMaxV2(data=c, segment_ids=tf.constant([0, 0, 1]), num_segments=2)

that `segment_ids[j] == i`.
If the product is empty for a given segment ID `i`, `output[i] = 1`.
Note: That this op is currently only supported with jit_compile=True.
The only difference with SegmentProd is the additional input `num_segments`.
This helps in evaluating the output shape in compile time.
`num_segments` should be consistent with segment_ids.
e.g. Max(segment_ids) - 1 should be equal to `num_segments` for a 1-d segment_ids
With inconsistent num_segments, the op still runs. only difference is,
the output takes the size of num_segments irrespective of size of segment_ids and data.
for num_segments less than expected output size, the last elements are ignored
for num_segments more than the expected output size, last elements are assigned 1.
For example:
>>> @tf.function(jit_compile=True)
... def test(c):
... return tf.raw_ops.SegmentProdV2(data=c, segment_ids=tf.constant([0, 0, 1]), num_segments=2)

r"""Selects elements from `x` or `y`, depending on `condition`.
The `x`, and `y` tensors must all have the same shape, and the
output will also have that shape.
The `condition` tensor must be a scalar if `x` and `y` are scalars.
If `x` and `y` are vectors or higher rank, then `condition` must be either a
scalar, a vector with size matching the first dimension of `x`, or must have
the same shape as `x`.
The `condition` tensor acts as a mask that chooses, based on the value at each
element, whether the corresponding element / row in the output should be
taken from `x` (if true) or `y` (if false).
If `condition` is a vector and `x` and `y` are higher rank matrices, then
it chooses which row (outer dimension) to copy from `x` and `y`.
If `condition` has the same shape as `x` and `y`, then it chooses which
element to copy from `x` and `y`.
For example:
```python
# 'condition' tensor is [[True, False]
# [False, True]]
# 't' is [[1, 2],
# [3, 4]]
# 'e' is [[5, 6],
# [7, 8]]
select(condition, t, e) # => [[1, 6], [7, 4]]
# 'condition' tensor is [True, False]
# 't' is [[1, 2],
# [3, 4]]
# 'e' is [[5, 6],
# [7, 8]]
select(condition, t, e) ==> [[1, 2],
[7, 8]]
```
Args:
condition: A `Tensor` of type `bool`.
x: A `Tensor` which may have the same shape as `condition`.
If `condition` is rank 1, `x` may have higher rank,
but its first dimension must match the size of `condition`.
y: A `Tensor` with the same type and shape as `x`.
name: A name for the operation (optional).
Returns:
A `Tensor`. Has the same type as `t`.

*NOTE*: `tf.subtract` supports broadcasting. More about broadcasting
[here](http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html)
Both input and output have a range `(-inf, inf)`.
Example usages below.
Subtract operation between an array and a scalar:
>>> x = [1, 2, 3, 4, 5]
>>> y = 1
>>> tf.subtract(x, y)
<tf.Tensor: shape=(5,), dtype=int32, numpy=array([0, 1, 2, 3, 4], dtype=int32)>
>>> tf.subtract(y, x)
<tf.Tensor: shape=(5,), dtype=int32,
numpy=array([ 0, -1, -2, -3, -4], dtype=int32)>
Note that binary `-` operator can be used instead:
>>> x = tf.convert_to_tensor([1, 2, 3, 4, 5])
>>> y = tf.convert_to_tensor(1)
>>> x - y
<tf.Tensor: shape=(5,), dtype=int32, numpy=array([0, 1, 2, 3, 4], dtype=int32)>
Subtract operation between an array and a tensor of same shape:
>>> x = [1, 2, 3, 4, 5]
>>> y = tf.constant([5, 4, 3, 2, 1])
>>> tf.subtract(y, x)
<tf.Tensor: shape=(5,), dtype=int32,
numpy=array([ 4, 2, 0, -2, -4], dtype=int32)>
**Warning**: If one of the inputs (`x` or `y`) is a tensor and the other is a
non-tensor, the non-tensor input will adopt (or get casted to) the data type
of the tensor input. This can potentially cause unwanted overflow or underflow
conversion.
For example,
>>> x = tf.constant([1, 2], dtype=tf.int8)
>>> y = [2**8 + 1, 2**8 + 2]
>>> tf.subtract(x, y)
<tf.Tensor: shape=(2,), dtype=int8, numpy=array([0, 0], dtype=int8)>
When subtracting two input values of different shapes, `tf.subtract` follows the
[general broadcasting rules](https://numpy.org/doc/stable/user/basics.broadcasting.html#general-broadcasting-rules)
. The two input array shapes are compared element-wise. Starting with the
trailing dimensions, the two dimensions either have to be equal or one of them
needs to be `1`.
For example,
>>> x = np.ones(6).reshape(2, 3, 1)
>>> y = np.ones(6).reshape(2, 1, 3)
>>> tf.subtract(x, y)
<tf.Tensor: shape=(2, 3, 3), dtype=float64, numpy=
array([[[0., 0., 0.],
[0., 0., 0.],
[0., 0., 0.]],
[[0., 0., 0.],
[0., 0., 0.],
[0., 0., 0.]]])>
Example with inputs of different dimensions:
>>> x = np.ones(6).reshape(2, 3, 1)
>>> y = np.ones(6).reshape(1, 6)
>>> tf.subtract(x, y)
<tf.Tensor: shape=(2, 3, 6), dtype=float64, numpy=
array([[[0., 0., 0., 0., 0., 0.],
[0., 0., 0., 0., 0., 0.],
[0., 0., 0., 0., 0., 0.]],
[[0., 0., 0., 0., 0., 0.],
[0., 0., 0., 0., 0., 0.],
[0., 0., 0., 0., 0., 0.]]])>

r"""Computes the maximum along segments of a tensor.
Read
[the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation)
for an explanation of segments.
This operator is similar to `tf.math.unsorted_segment_sum`,
Instead of computing the sum over segments, it computes the maximum such that:
\\(output_i = \max_{j...} data[j...]\\) where max is over tuples `j...` such
that `segment_ids[j...] == i`.
If the maximum is empty for a given segment ID `i`, it outputs the smallest
possible value for the specific numeric type,
`output[i] = numeric_limits<T>::lowest()`.
If the given segment ID `i` is negative, then the corresponding value is
dropped, and will not be included in the result.
Caution: On CPU, values in `segment_ids` are always validated to be less than
`num_segments`, and an error is thrown for out-of-bound indices. On GPU, this
does not throw an error for out-of-bound indices. On Gpu, out-of-bound indices
result in safe but unspecified behavior, which may include ignoring
out-of-bound indices or outputting a tensor with a 0 stored in the first
dimension of its shape if `num_segments` is 0.

r"""Computes the product along segments of a tensor.
Read
[the section on segmentation](https://tensorflow.org/api_docs/python/tf/math#Segmentation)
for an explanation of segments.
This operator is similar to `tf.math.unsorted_segment_sum`,
Instead of computing the sum over segments, it computes the product of all
entries belonging to a segment such that:
\\(output_i = \prod_{j...} data[j...]\\) where the product is over tuples
`j...` such that `segment_ids[j...] == i`.
For example:
>>> c = tf.constant([[1,2,3,4], [5,6,7,8], [4,3,2,1]])
>>> tf.math.unsorted_segment_prod(c, tf.constant([0, 1, 0]), num_segments=2).numpy()
array([[4, 6, 6, 4],
[5, 6, 7, 8]], dtype=int32)
If there is no entry for a given segment ID `i`, it outputs 1.
If the given segment ID `i` is negative, then the corresponding value is
dropped, and will not be included in the result.
Caution: On CPU, values in `segment_ids` are always validated to be less than
`num_segments`, and an error is thrown for out-of-bound indices. On GPU, this
does not throw an error for out-of-bound indices. On Gpu, out-of-bound indices
result in safe but unspecified behavior, which may include ignoring
out-of-bound indices or outputting a tensor with a 0 stored in the first
dimension of its shape if `num_segments` is 0.
Args:
data: A `Tensor`. Must be one of the following types: `float32`, `float64`, `int32`, `uint8`, `int16`, `int8`, `complex64`, `int64`, `qint8`, `quint8`, `qint32`, `bfloat16`, `qint16`, `quint16`, `uint16`, `complex128`, `half`, `uint32`, `uint64`.
segment_ids: A `Tensor`. Must be one of the following types: `int32`, `int64`.
A tensor whose shape is a prefix of `data.shape`.
The values must be less than `num_segments`.
Caution: The values are always validated to be in range on CPU, never validated
on GPU.
num_segments: A `Tensor`. Must be one of the following types: `int32`, `int64`.
name: A name for the operation (optional).
Returns:
A `Tensor`. Has the same type as `data`.
