8. MLFlow

MLflow

• https://mlflow.org/
• Narzędzie podobne do omawianego na poprzednich zajęciach Sacred
• Nieco inne podejście: mniej ingerencji w istniejący kod
• Bardziej kompleksowe rozwiązanie: 4 komponenty, pierwszy z nich ma funkcjonalność podobną do Sacred
• Działa "z każdym" językiem. A tak naprawdę: Python, R, Java + CLI API + REST API
• Popularna wśród pracodawców - wyniki wyszukiwania ofert pracy: 20 ofert (https://pl.indeed.com/), 36 ofert (linkedin). Sacred: 0
• Integracja z licznymi bibliotekami / chmurami
• Rozwiązanie OpenSource, stworzone przez firmę Databricks
• Dostępna odpłatna wersja "Managed" (w ordóżnieniu od "self-hosted")

Komponenty

MLflow składa się z czterech niezależnych komponentów:

• MLflow Tracking - pozwala śledzić zmiany parametrów, kodu, środowiska i ich wpływ na metryki. Jest to funkcjonalność bardzo zbliżona do tej, którą zapewnia Sacred

• MLflow Projects - umożliwia "pakowanie" kodu ekserymentów w taki sposób, żeby mogłby być w łatwy sposób zreprodukowane przez innych

• MLflow Models - ułatwia "pakowanie" modeli uczenia maszynowego

• MLflow Registry - zapewnia centralne miejsce do przechowywania i współdzielenia modeli. Zapewnia narzędzia do wersjonowania i śledzenia pochodzenia tych modeli.

  Komponenty te mogą być używane razem bądź oddzielnie.

MLflow Tracking - przykład

Porównywanie wyników

Logowanie

• logowania metryk i parametrów można dokonać m.in. poprzez wywołania Python-owego API: mlflow.log_param() i mlflow.log_metric(). Więcej dostępnych funkcji: link

• wywołania te muszą nastąpić po wykonaniu mlflow.start_run(), najlepiej wewnątrz bloku:

  with mlflow.start_run():
       
       #[...]
  
       mlflow.log_param("alpha", alpha)
       mlflow.log_param("l1_ratio", l1_ratio)
  

• jest też możliwość automatycznego logwania dla wybranych bibliotek: https://mlflow.org/docs/latest/tracking.html#automatic-logging

MLflow Projects

• MLflow projects to zestaw konwencji i kilku narzędzi
• ułatwiają one uruchamianie eskperymentów

Konfiguracja projektu

• W pliku MLproject zapisuje się konfigurację projektu (specyfikacja)
• Zawiera ona:
  • odnośnik do środowiska, w którym ma być wywołany eksperyment szczegóły:
    • nazwa obrazu Docker
    • albo ścieżka do pliku conda.yaml definiującego środowisko wykonania Conda
  • parametry, z którymi można wywołać eksperyment
  • polecenia służące do wywołania eksperymentu

%%writefile IUM_08/examples/sklearn_elasticnet_wine/MLproject
name: tutorial

conda_env: conda.yaml #ścieżka do pliku conda.yaml z definicją środowiska
    
#docker_env:
#  image: mlflow-docker-example-environment

entry_points:
  main:
    parameters:
      alpha: {type: float, default: 0.5}
      l1_ratio: {type: float, default: 0.1}
    command: "python train.py {alpha} {l1_ratio}"
  test:
    parameters:
      alpha: {type: cutoff, default: 0}
    command: "python test.py {cutoff}"

Środowisko Conda

• https://docs.conda.io
• Składnia plików conda.yaml definiujących środowisko: https://docs.conda.io/projects/conda/en/4.6.1/user-guide/tasks/manage-environments.html#create-env-file-manually
• Składnia YAML: przystępnie, oficjalnie

    - mlflow>=1.0

Overwriting IUM_08/examples/sklearn_elasticnet_wine/conda.yaml

Środowisko docker

• zamiast środowiska Conda możemy również podać nazwę obrazu docker, w którym ma być wywołany eksperyment.
• obraz będzie szukany lokalnie a następnie na DockerHub, lub w innym repozytorium dockera
• składnia specyfikacji ścieżki jest taka sama jak w przypadki poleceń dockera, np. docker pull link
• Można również podać katalogi do podmontowania wewnątrz kontenera oraz wartości zmiennych środowiskowych do ustawienia w kontenerze:

  docker_env:
   image: mlflow-docker-example-environment
   volumes: ["/local/path:/container/mount/path"]
   environment: [["NEW_ENV_VAR", "new_var_value"], "VAR_TO_COPY_FROM_HOST_ENVIRONMENT"]
  

Parametry

• Specyfikacja parametrów w pliku MLproject pozwala na ich walidację i używanie wartości domyślnych

• Dostępne typy:

  • String
  • Float - dowolna liczba (MLflow waliduje, czy podana wartość jest liczbą)
  • Path - pozwala podawać ścieżki względne (przekształca je na bezwzlędne) do plików lokalnych albo do plików zdalnych (np. do s3://) - zostaną wtedy ściągnięte lokalnie
  • URI - podobnie jak path, ale do rozproszonych systemów plików

• Składnia

  parameter_name: {type: data_type, default: value}  # Short syntax
  
  parameter_name:     # Long syntax
     type: data_type
     default: value
  

Uruchamianie projektu

• Projekt możemy uruchomić przy pomocy polecenia mlflow run (dokumentacja)
• Spowoduje to przygotowanie środowiska i uruchomienie eksperymentu wewnątrz środowiska
• domyślnie zostanie uruchomione polecenie zdefiniowane w "entry point" main. Żeby uruchomić inny "entry point", możemy użyć parametru -e, np:

  mlflow run sklearn_elasticnet_wine -e test
  

• Parametry do naszego polecenia możemy przekazywać przy pomocy flagi -P

!cd IUM_08/examples/; mlflow run sklearn_elasticnet_wine -P alpha=0.42

Zadania [10p pkt]

1. Dodaj do swojego projektu logowanie parametrów i metryk za pomocą MLflow (polecenia mlflow.log_param i mlflow.log_metric
2. Dodaj plik MLProject definiujący polecenia do trenowania i testowania, ich parametry wywołania oraz środowisko (Conda albo Docker)

MLflow Models

MLflow Models to konwencja zapisu modeli, która ułatwia potem ich załadowanie i użycie

Rodzaje modeli ("flavors") wspierane przez MLflow:

• Python Function (python_function)
• PyTorch (pytorch)
• TensorFlow (tensorflow)
• Keras (keras)
• Scikit-learn (sklearn)
• Spacy(spaCy)
• ONNX (onnx)
• R Function (crate)
• H2O (h2o)
• MLeap (mleap)
• Spark MLlib (spark)
• MXNet Gluon (gluon)
• XGBoost (xgboost)
• LightGBM (lightgbm)
• CatBoost (catboost)
• Fastai(fastai)
• Statsmodels (statsmodels)

Zapisywanie modelu

Model ML można zapisać w MLflow przy pomocy jednej z dwóch funkcji z pakietu odpowiadającego używanej przez nas bibliotece:

• save_model() - zapisuje model na dysku
• log_model() - zapisuje model razem z innymi informacjami (metrykami, parametrami). W zależności od ustawień "tracking_uri" może być to lokalny folder w mlruns/ lub ścieżka na zdalnym serwerze MLflow

        mlflow.sklearn.save_model(lr, "my_model")

        mlflow.keras.save_model(lr, "my_model")

Wywołanie tej funkcji spowoduje stworzenie katalogu "my_model" zawierającego:

• plik _MLmodel zawierający informacje o sposobach, w jaki model można załadować ("flavors") oraz ścieżki do plików związanych z modelem, takich jak:
  • _conda.yaml - opis środowiska potrzebnego do załadowania modelu
  • _model.pkl - plik z zserializowanym modelem

Tylko plik _MLmodel jest specjalnym plikiem MLflow - reszta zależy od konkrentego "flavour"

MLflow Registry

• umożliwia zapisywanie i ładowanie modeli z centralnego rejestru
• Modele można też serwować bezpośrednio z rejestru:

#!/usr/bin/env sh

# Set environment variable for the tracking URL where the Model Registry resides
export MLFLOW_TRACKING_URI=http://localhost:5000

# Serve the production model from the model registry
mlflow models serve -m "models:/sk-learn-random-forest-reg-model/Production"

• Żeby było to możliwe, musimy mieć uruchomiony serwer MLflow
• Umożliwia zarządzanie wersjami modeli i oznaczanie ich różnymi fazami, np. "Staging", "Production"

Zadania (termin: 14.05 EOD)

1. [2 pkt] Dodaj do joba treningowego wywołania MLflow, tak, żeby przy każdym uruchomieniu stworzyć i zarchiwizować katalog z modelem. Plik MLmodel powinien zawierać pola:

• signature

• input_example

  Folder powinien również zawierać definicję środowiska - conda lub docker, umożliwiającego uruchomienie projektu.

2. [6 pkt] Wybierz jedną osobę z grupy. Załóżmy, że Twoje ID to s123456 a jej s654321. Stwórz na Jenkinsie projekt s123456-predict-s654321, w którym:

• pobierzesz artefakt z zapisanym modelem z joba osoby s654321
• dokonasz na nim predykcji danych wejściowych podanych w formacie json jako parametr zadania Jenkinsowego. Domyślną wartością tego parametru niech będą przykładowe dane wejściowe z input_example

3. [1 pkt] Zarejestruj swój model w MLflow registry

4. [6 pkt] Stwórz na Jenkinsie projekt s123456-predict-s654321-from-registry, który zrealizuje to samo zadanie co s123456-predict-s654321, ale tym razem pobierze model z rejestru MLflow zamiast z artefaktów Jenkinsa
