Inżynieria uczenia maszynowego
10. DVC [laboratoria]
Tomasz Ziętkiewicz (2022)
DVC - Data Version Control
- dvc.org
- "Version Control System for Machine Learning Projects" (System kontroli wersji dla projektów uczenia maszynowego)
- Open Source
- Umożliwia:
- wersjonowanie danych i modeli. "Git dla danych i modeli"
- budowanie potoków ("pipeline") definiujących jak budować/trenować/ewaluować modele. "Makefile dla uczenia maszynowego"
- śledzenie, porównywanie metryk i parametrów
- ściśle zintegowany z gitem
- działa niezależnie od używanego języka/bibliotek i systemu operacyjnego
- 5-minutowe wprowadzenie: https://www.youtube.com/watch?v=UbL7VUpv1Bs&t=197s

Stwórzmy katalog, w którym będziemy przechowywać nasz projekt:
!mkdir -p IUM_10/sample-ml-project#Jupyter notebook magic https://ipython.readthedocs.io/en/stable/interactive/magics.html#magic-cd
%cd "IUM_10/sample-ml-project"/home/tomek/AITech/repo/aitech-ium-private/IUM_10/sample-ml-project
Inicjalizujemy puste repozytorium Git (możemy też pominąć ten krok i działać w istniejącym już repozytorium)
!git initInitialized empty Git repository in /home/tomek/AITech/repo/aitech-ium-private/IUM_10/sample-ml-project/.git/

Zobaczmy jakie pliki dodał (również do repozytorium git) DVC. Ich opis znajdziemy tutaj: https://dvc.org/doc/user-guide/project-structure/internal-files

Możemy teraz zacommitować zmiany w git:
!git commit -m "Initial commit"On branch master nothing to commit, working tree clean
Śledzenie plików za pomocą DVC
- dużymi plikami, takimi jak plikami z danymi wejściowymi czy plikami modeli, trudno zarządza się za pomocą gita, ze względu na problemy z:
- wydajnością
- przestrzenią w repozytorium
- ograniczenia ze strony serwisu (np. limit 100 MB na plik w Github)
- Git posiada rozszerzenie lfs(Large File Storage), które stanowi pewne rozwiązanie tego problemu. Same pliki przechowywane są na specjalnym zdalnym serwerze, w repozytorium przechowywane są jedynie odnośniki do tych plików i pewne metadane
- DVC proponuje podobne podejście, ale:
Przygotujmy przykładowe dane, pobierając je z Kaggle:
!kaggle datasets download -d uciml/iris
!unzip -o iris.zip
!rm database.sqlite iris.zip
!mkdir -p data
!mv Iris.csv data/Downloading iris.zip to /home/tomek/AITech/repo/aitech-ium-private/IUM_10/sample-ml-project 0%| | 0.00/3.60k [00:00<?, ?B/s] 100%|██████████████████████████████████████| 3.60k/3.60k [00:00<00:00, 2.63MB/s] Archive: iris.zip inflating: Iris.csv inflating: database.sqlite
Teraz dodamy plik(i) z danymi do DVC:
!dvc add data/Iris.csvAdding... ![A 0%| |.E8dZEGBYoRayYsJLdesNS4.tmp 0.00/5.11k [00:00<?, ?it/s][A 100% Add|██████████████████████████████████████████████|1/1 [00:04, 4.71s/file][A To track the changes with git, run: git add data/Iris.csv.dvc data/.gitignore [0m
- DVC utworzył plik
data/Iris.csv.dvci dadał oryginalny plik do.gitignore - W repozytorium będzie obecny tylko plik
*.dvc, zawierający odnośnik do prawdziwego pliku
!git status -uOn branch master Untracked files: (use "git add <file>..." to include in what will be committed) [31mdata/.gitignore[m [31mdata/Iris.csv.dvc[m [31miris.zip[m nothing added to commit but untracked files present (use "git add" to track)
Dodajmy pliki data/Iris.csv.dvc data/.gitignore do repozytorium git, zgodnie z sugestią DVC:
!git add data/Iris.csv.dvc data/.gitignore!git commit -m "Dodano dane IRIS (DVC)"[master cc0821a] Dodano dane IRIS (DVC) 2 files changed, 5 insertions(+) create mode 100644 data/.gitignore create mode 100644 data/Iris.csv.dvc
Plik *.dvc zawiera m.in. hash pliku. Więcej o plikach *.dvc: link
# %load data/Iris.csv.dvc
outs:
- md5: 717820ef0af287ff346c5cabfb4c612c
size: 5107
path: Iris.csv
Oryginalny plik Iris.csv został przeniesiony do katalogu ./dvc/cache/{wartość hash pliku) i podlinkowany z powrotem do oryginalnej lokalizacji. Sposób tworzenia linków może być różny w zależności od systemu plików.
!ls -l .dvc/cache/71total 8 -r--r--r-- 1 tomek tomek 5107 wrz 19 2019 7820ef0af287ff346c5cabfb4c612c
!ls -l ./datals: cannot access './data': No such file or directory
dvc remote
- żeby wysłać właściwe pliki śledzone przez DVC do zdalnej lokalizacji (z której będą mogłby być pobrane np. przez system CI albo innych użytkowników) musimy mieć skonfigurowaną taką lokazliację
- służy do tego polecenie
dvc remote add - użyjemy lokalnego "remote". Tutaj będzie to po prostu utworzony wcześniej katalog
/dvcstore. Taki katalog istnieje też na naszym Jenkinsie, oczywiście należy go podmontować w Dockerze - w realnych zastosowaniach podalibyśmy tutaj ścieżkę do jakiegoś zasobu dostępnego przez inernet jak np. serwer SFTP, ścieżka do AWS S3 itp.
Obsługiwane typy zdalnych lokalizacji (remotes): https://dvc.org/doc/command-reference/remote/add#supported-storage-types
- Amazon S3
- S3-compatible storage
- Microsoft Azure Blob Storage
- Google Drive
- Google Cloud Storage
- Aliyun OSS
- SSH
- HDFS
- WebHDFS
- HTTP
- WebDAV
- local remote
!dvc remote add -d my_local_remote /dvcstoreSetting 'my_local_remote' as a default remote.
[0m!git statusOn branch master Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git restore <file>..." to discard changes in working directory) [31mmodified: .dvc/config[m no changes added to commit (use "git add" and/or "git commit -a")
!git add .dvc/config
!git commit -m "Added DVC remote"[master 3ff62b6] Added DVC remote 1 file changed, 4 insertions(+)
dvc push
Kiedy mamy już skonfigurowany "remote" możemy wypchnąć do niego pliki korzystając z polecenia dvc push:
!dvc push!tree /dvcstore[34;42m/dvcstore[00m └── [01;34m71[00m └── 7820ef0af287ff346c5cabfb4c612c 1 directory, 1 file
dvc pull
Żeby pobrać dane z DVC (np. w innej lokalizacji, przez innego użytkownika), musimy:
- sklonować repozytorium git (żeby m.in. pobrać pliki
*.dvc - wykonać
dvc pull
Dodawanie nowych plików i modyfikacja istniejących wygląda podobnie jak przy zwykłych plikach śledzonych przez git, tylko zamiast git używamy polecenia dvc a dodatkowo pamiętamy o zarządzaniu plikami *.dvc za pomocą gita:
!head -n -1 data/Iris.csv | sponge data/Iris.csv!git statusOn branch master nothing to commit, working tree clean
!dvc statusdata/Iris.csv.dvc: core[39m> changed outs: modified: data/Iris.csv [0m

!git add data/Iris.csv.dvc
!git commit -m "Removed last line from Iris dataset"
[master e38c244] Removed last line from Iris dataset 1 file changed, 2 insertions(+), 2 deletions(-)
dvc checkout
- Polecenia
dvc checkoutużywamy razem zgit checkout, żeby zmienić branch, na którym pracujemy. - DVC podmieni wersje plików śledzonych przez siebie na pochodzące z innego brancha (o ile pliki te się różnią i różnią się pliki
*.dvcw odpowiednich branchach - zmiana brancha przez git powoduje (ewentualną) zmianę plików
*.dvcadvc checkoutkopiuje/linkuje pliki z katalogu.dvc/cacheo wartościach hash odpowiadających tym z plików*.dvc
Wymiana danych między projektami
- za pomocą poleceń
dvc importidvc updatemożemy dodać i później aktualizować pliki śledzone przez DVC w innym repozytorium

DVC pipelines
- wprowadzenie: https://youtu.be/71IGzyH95UY
- Getting started: https://dvc.org/doc/start/data-pipelines
- dvc pipelines pozwala nam zbudować (za pomocą polecenie
dvc run) lub zdefiniować (edytując plikdvc.yaml) graf zależności między krokami wykonywanymi w naszym projekcie (takimi jak "przygotowanie danych", "trenowanie", "ewaluacja") - tak zdefiniowany pipeline można potem uruchomić za pomocą polecenia
dvc reproduce
Zadania [15pkt]
- Zainicjalizuj repozytorium DVC wewnątrz Twojego repozytorium z projektem [1pkt]
- Dodaj plik(i) z danymi w Twoim projekcie do DVC [1pkt]
- Skonfiguruj remote (dane do konfiguracji podane poniżej) [3pkt]
- Stwórz/zdefiniuj i dodaj do repozytorium plik
dvc.yamlopisujący kroki wykonywane w Twoim projekcie. Wydziel przynajmniej 2 kroki (np. przygotowanie danych/trenowanie) powiązane ze sobą za pomocą zależności (skorzystaj z materiałów "Getting started", link powyżej) [6pkt] - Stwórz projekt na Jenkinsie (
s1233456-dvc), w którym sklonujesz repozytorium, ściągniesz pliki dvc (za pomocądvc pull) i uruchomisz pipeline (za pomocądvc reproduce) [4pkt]
SSH remote
Jednym z remote obsługiwanych przez DVC jest SFTP/SSH.
W celu jego wykorzystania na serwerze tzietkiewicz.vm.wmi.amu.edu.pl utworzony został użytkownik ium-sftp i skonfigurowany serwer SFTP.
Został też dla niego wygenerowany klucz ssh, który został dodany jako "Jenkins credential" (patrz opis konfiguracji na Jenkins poniżej)

Jenkins
W Jenkins można użyć mechanizmu "Credentials", żeby w bezpieczny sposób przekazać hasło albo klucz prywatny.
Takie dane dla użytkownika ium-sftp zostały stworzone na Jenkinsie:
- typu ssh key: https://tzietkiewicz.vm.wmi.amu.edu.pl:8080/credentials/store/system/domain/_/credential/48ac7004-216e-4260-abba-1fe5db753e18/
- typu "secret text" - zawierający hasło użytkownika ium-shftp: https://tzietkiewicz.vm.wmi.amu.edu.pl:8080/credentials/store/system/domain/_/credential/ium-sftp-password/
Opis używania "Credentials" w Jenkinsfile: https://www.jenkins.io/doc/book/pipeline/jenkinsfile/#for-other-credential-types
Klucza ssh można użyć tak:
withCredentials(
[sshUserPrivateKey(credentialsId: '48ac7004-216e-4260-abba-1fe5db753e18', keyFileVariable: 'IUM_SFTP_KEY', passphraseVariable: '', usernameVariable: '')]) {
sh 'dvc remote add -d ium_ssh_remote ssh://ium-sftp@tzietkiewicz.vm.wmi.amu.edu.pl/ium-sftp'
sh 'dvc remote modify --local ium_ssh_remote keyfile $IUM_SFTP_KEY'
sh 'dvc pull'}
Secret text tak:
withCredentials([string(credentialsId: 'ium-sftp-password', variable: 'IUM_SFTP_PASS')]) {
sh 'dvc remote add -d ium_ssh_remote ssh://ium-sftp@tzietkiewicz.vm.wmi.amu.edu.pl/ium-sftp'
sh 'dvc remote modify --local ium_ssh_remote password $IUM_SFTP_KEY'
sh 'dvc pull'
}
