Демонстрация набора инструментов для моделей MLMD

Задний план

В этой записной книжке показано, как создать карту модели с помощью набора инструментов Model Card Toolkit с конвейером MLMD и TFX в среде Jupyter/Colab. Вы можете узнать больше о модели карт на https://modelcards.withgoogle.com/about

Настраивать

Сначала нам нужно а) установить и импортировать необходимые пакеты и б) загрузить данные.

Обновите до Pip 20.2 и установите TFX

pip install -q --upgrade pip==20.2
pip install -q "tfx==0.26.0"
pip install -q model-card-toolkit

Вы перезапустили среду выполнения?

Если вы используете Google Colab, при первом запуске указанной выше ячейки необходимо перезапустить среду выполнения (Время выполнения > Перезапустить среду выполнения...). Это связано с тем, как Colab загружает пакеты.

Импорт пакетов

Мы импортируем необходимые пакеты, в том числе стандартные классы компонентов TFX и проверяем версии библиотек.

Создайте интерактивный контекст

Наконец, мы создаем InteractiveContext, который позволит нам интерактивно запускать компоненты TFX в этой записной книжке.

# Here, we create an InteractiveContext using default parameters. This will
# use a temporary directory with an ephemeral ML Metadata database instance.
# To use your own pipeline root or database, the optional properties
# `pipeline_root` and `metadata_connection_config` may be passed to
# InteractiveContext. Calls to InteractiveContext are no-ops outside of the
# notebook.
context = InteractiveContext()
WARNING:absl:InteractiveContext pipeline_root argument not provided: using temporary directory /tmp/tfx-interactive-2021-02-05T22_01_17.129037-teowo3b1 as root for pipeline outputs.
WARNING:absl:InteractiveContext metadata_connection_config not provided: using SQLite ML Metadata database at /tmp/tfx-interactive-2021-02-05T22_01_17.129037-teowo3b1/metadata.sqlite.

Интерактивный запуск компонентов TFX

В следующих ячейках мы создаем компоненты TFX один за другим, запускаем каждый из них и визуализируем их выходные артефакты. В этом ноутбуке, мы не будем предоставлять подробные объяснения каждого компонента TFX, но вы можете увидеть , что каждый делает в мастерской TFX Colab .

СтатистикаGen

StatisticsGen принимает в качестве входных данных набора данных , мы просто проглоченные с помощью ExampleGen и позволяет выполнить некоторый анализ набора данных с помощью TensorFlow Data Validation (TFDV).

WARNING:tensorflow:5 out of the last 5 calls to <function recreate_function.<locals>.restored_function_body at 0x7f77a02d2510> triggered tf.function retracing. Tracing is expensive and the excessive number of tracings could be due to (1) creating @tf.function repeatedly in a loop, (2) passing tensors with different shapes, (3) passing Python objects instead of tensors. For (1), please define your @tf.function outside of the loop. For (2), @tf.function has experimental_relax_shapes=True option that relaxes argument shapes that can avoid unnecessary retracing.

Заполнение свойств из ModelCard с помощью Model Card Toolkit

Теперь, когда мы настроили наш конвейер TFX, мы будем использовать набор инструментов Model Card Toolkit для извлечения ключевых артефактов из запуска и заполнения Model Card.

Подключитесь к хранилищу MLMD, используемому InteractiveContext.

from ml_metadata.metadata_store import metadata_store
from IPython import display

mlmd_store = metadata_store.MetadataStore(context.metadata_connection_config)
model_uri = trainer.outputs["model"].get()[0].uri
INFO:absl:MetadataStore with DB connection initialized

Используйте инструментарий карты модели

Инициализируйте набор инструментов Model Card.

from model_card_toolkit import ModelCardToolkit

mct = ModelCardToolkit(mlmd_store=mlmd_store, model_uri=model_uri)

Создайте рабочую область карты модели.

model_card = mct.scaffold_assets()

Аннотируйте больше информации в карточке модели.

Также важно документировать информацию о модели, которая может быть важна для последующих пользователей, например, ее ограничения, предполагаемые варианты использования, компромиссы и этические соображения. Для каждого из этих разделов мы можем напрямую добавить новые объекты JSON для представления этой информации.

    'earners is just over 3:1. Due to the imbalance across income levels, we '
    'can see that our true negative rate seems quite high, while our true '
    'positive rate seems quite low. This is true to an even greater degree '
    'when we only look at the “female” sub-group, because there are even '
    'fewer female examples in the $50,000+ earner group, causing our model to '
    'overfit these examples. To avoid this, we can try various remediation '
    'strategies in future iterations (e.g. undersampling, hyperparameter '

Фильтровать и добавлять графики.

Мы можем отфильтровать графики, созданные компонентами TFX, чтобы включить те, которые наиболее важны для карты модели, используя функцию, определенную ниже. В этом примере мы фильтруем для race и sex , два потенциально чувствительных атрибутов.

Каждая карточка модели будет иметь до трех разделов для графиков: статистика набора данных для обучения, статистика набора данных для оценки и количественный анализ производительности нашей модели.
