Поэтапное знакомство с TensorFlow Extended (TFX)
 Посмотреть на TensorFlow.org |  Запускаем в Google Colab |  Посмотреть исходный код на GitHub |  Скачать блокнот |
Это руководство на основе Colab будет интерактивно проходить через каждый встроенный компонент TensorFlow Extended (TFX).
Он охватывает каждый этап непрерывного конвейера машинного обучения, от приема данных до продвижения модели и обслуживания.
Когда вы закончите, содержимое этой записной книжки может быть автоматически экспортировано как исходный код конвейера TFX, который можно организовать с помощью Apache Airflow и Apache Beam.
Задний план
Этот блокнот демонстрирует, как использовать TFX в среде Jupyter / Colab. Здесь мы рассмотрим пример Chicago Taxi в интерактивной записной книжке.
Работа в интерактивной записной книжке - полезный способ познакомиться со структурой конвейера TFX. Это также полезно при разработке ваших собственных конвейеров в качестве облегченной среды разработки, но вы должны знать, что существуют различия в способах оркестровки интерактивных записных книжек и в том, как они получают доступ к артефактам метаданных.
Оркестровка
В производственном развертывании TFX вы будете использовать оркестратор, такой как Apache Airflow, Kubeflow Pipelines или Apache Beam, для оркестрации заранее определенного конвейерного графа компонентов TFX. В интерактивной записной книжке записная книжка сама по себе является оркестратором, запускающим каждый компонент TFX по мере того, как вы выполняете ячейки записной книжки.
Метаданные
В производственном развертывании TFX вы получите доступ к метаданным через API метаданных ML (MLMD). MLMD хранит свойства метаданных в базе данных, такой как MySQL или SQLite, и сохраняет полезные данные метаданных в постоянном хранилище, например в вашей файловой системе. В интерактивном ноутбуке, оба свойства и полезные нагрузки, хранятся в базе данных SQLite эфемерных в /tmp каталог на портативном компьютере или сервере Jupyter Colab.
Настраивать
Сначала мы устанавливаем и импортируем необходимые пакеты, настраиваем пути и загружаем данные.
Обновить Pip
Чтобы избежать обновления Pip в системе при локальном запуске, убедитесь, что мы работаем в Colab. Конечно, локальные системы можно модернизировать отдельно.
try:
import colab
!pip install --upgrade pip
except:
pass
Установить TFX
pip install -U tfx
Вы перезапускали среду выполнения?
Если вы используете Google Colab, при первом запуске указанной выше ячейки вы должны перезапустить среду выполнения (Runtime> Restart runtime ...). Это связано с тем, как Colab загружает пакеты.
Импортировать пакеты
Импортируем необходимые пакеты, включая стандартные классы компонентов TFX.
import os
import pprint
import tempfile
import urllib
import absl
import tensorflow as tf
import tensorflow_model_analysis as tfma
tf.get_logger().propagate = False

Скачать пример данных
Мы загружаем пример набора данных для использования в нашем конвейере TFX.
Набор данных мы используем это такси Trips набор данных выпущен городом Чикаго. Столбцы в этом наборе данных:
| pickup_community_area | транспортные расходы | trip_start_month |
| trip_start_hour | trip_start_day | trip_start_timestamp |
| pickup_latitude | pickup_longitude | dropoff_latitude |
| dropoff_longitude | trip_miles | pickup_census_tract |
| dropoff_census_tract | способ оплаты | Компания |
| trip_seconds | dropoff_community_area | подсказки |
С помощью этого набора данных, мы будем строить модель , которая предсказывает tips о поездке.
_data_root = tempfile.mkdtemp(prefix='tfx-data')
DATA_PATH = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/chicago_taxi_pipeline/data/simple/data.csv'

Создайте InteractiveContext
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()

Интерактивный запуск компонентов TFX
В следующих ячейках мы создаем компоненты TFX один за другим, запускаем каждый из них и визуализируем их выходные артефакты.
ExampleGen
ExampleGen компонент, как правило , в начале TFX трубопровода. Будет:
- Разделить данные на обучающие и оценочные наборы (по умолчанию 2/3 обучения + 1/3 оценки)
- Преобразование данных в
tf.Exampleформате (узнать больше здесь ) - Копирование данных в
_tfx_rootкаталог для других компонентов для доступа
ExampleGen принимает в качестве входных данных пути к источнику данных. В нашем случае, это _data_root путь , который содержит загруженное CSV.
example_gen = tfx.components.CsvExampleGen(input_base=_data_root)
context.run(example_gen)

Давайте рассмотрим выходные артефакты ExampleGen . Этот компонент создает два артефакта, примеры обучения и примеры оценки:
artifact = example_gen.outputs['examples'].get()[0]
print(artifact.split_names, artifact.uri)
["train", "eval"] /tmp/tfx-interactive-2021-12-05T10_59_24.898354-se36qxc4/CsvExampleGen/examples/1
Мы также можем взглянуть на первые три обучающих примера:
# Get the URI of the output artifact representing the training examples, which is a directory
train_uri = os.path.join(example_gen.outputs['examples'].get()[0].uri, 'Split-train')
# Get the list of files in this directory (all compressed TFRecord files)
tfrecord_filenames = [os.path.join(train_uri, name)
for name in os.listdir(train_uri)]
# Create a `TFRecordDataset` to read these files
dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")
# Iterate over the first 3 records and decode them.
for tfrecord in dataset.take(3):
serialized_example = tfrecord.numpy()

Теперь, когда ExampleGen закончил глотание данных, следующий шаг является анализом данных.
СтатистикаGen
В StatisticsGen статистика компонента Вычисляет более набор данных для анализа данных, а также для использования в последующих компонентах. Он использует TensorFlow Data Validation библиотеку.
StatisticsGen принимает в качестве входных данных набора данных , мы просто проглоченные с помощью ExampleGen .
statistics_gen = tfx.components.StatisticsGen(examples=example_gen.outputs['examples'])
context.run(statistics_gen)

После StatisticsGen завершения работы, мы можем визуализировать выведенную статистику. Попробуйте поиграть с разными сюжетами!
context.show(statistics_gen.outputs['statistics'])
SchemaGen
SchemaGen компонент создает схему , основанную на статистике данных. (Схема определяет ожидаемые границы, типы и свойства функций в наборе данных) . Он также использует TensorFlow Data Validation библиотеку.
SchemaGen будет принимать в качестве входных данных статистики , которые мы получили с StatisticsGen , глядя на учебный раскол по умолчанию.
schema_gen = tfx.components.SchemaGen(
statistics=statistics_gen.outputs['statistics'],
infer_feature_shape=False)

После SchemaGen завершения работы, мы можем визуализировать сформированную схему в виде таблицы.
context.show(schema_gen.outputs['schema'])
Каждая функция в вашем наборе данных отображается в таблице схемы в виде строки вместе со своими свойствами. Схема также фиксирует все значения, которые принимает категориальный признак, обозначенный как его домен.
Чтобы узнать больше о схемах, см документации SchemaGen .
ExampleValidator
ExampleValidator компонент обнаруживает аномалии в данных, на основе ожиданий , определенных в схеме. Он также использует TensorFlow Data Validation библиотеку.
ExampleValidator будет принимать в качестве входных данных статистики из StatisticsGen и схемы из SchemaGen .
example_validator = tfx.components.ExampleValidator(
statistics=statistics_gen.outputs['statistics'],
schema=schema_gen.outputs['schema'])
context.run(example_validator)
INFO:absl:Excluding no splits because exclude_splits is not set.

После ExampleValidator завершения работы, мы можем визуализировать аномалии в виде таблицы.
context.show(example_validator.outputs['anomalies'])
В таблице аномалий мы видим, что аномалий нет. Это то, чего мы ожидали, поскольку это первый набор данных, который мы проанализировали, и схема адаптирована к нему. Вам следует просмотреть эту схему - все неожиданное означает аномалию в данных. После проверки схему можно использовать для защиты будущих данных, а созданные здесь аномалии можно использовать для отладки производительности модели, понимания того, как ваши данные развиваются с течением времени, и выявления ошибок данных.
Преобразовать
Transform компонент выполняет функцию инженерии как для подготовки и обслуживания. Он использует TensorFlow преобразование библиотеки.
Transform будет принимать в качестве входных данных из ExampleGen , схемы из SchemaGen , а также модуль, содержащий определенные пользователем преобразования кода.
Давайте рассмотрим пример определяемого пользователя преобразования кода ниже (для введения в TensorFlow Transform API - интерфейсы, можно найти в учебнике ). Сначала мы определяем несколько констант для проектирования функций:
_taxi_constants_module_file = 'taxi_constants.py'
%%writefile {_taxi_constants_module_file}
# Categorical features are assumed to each have a maximum value in the dataset.
MAX_CATEGORICAL_FEATURE_VALUES = [24, 31, 12]
CATEGORICAL_FEATURE_KEYS = [
'trip_start_hour', 'trip_start_day', 'trip_start_month',
'pickup_census_tract', 'dropoff_census_tract', 'pickup_community_area',
'dropoff_community_area'
]
DENSE_FLOAT_FEATURE_KEYS = ['trip_miles', 'fare', 'trip_seconds']
# Number of buckets used by tf.transform for encoding each feature.
FEATURE_BUCKET_COUNT = 10
BUCKET_FEATURE_KEYS = [
'pickup_latitude', 'pickup_longitude', 'dropoff_latitude',
'dropoff_longitude'
]
# Number of vocabulary terms used for encoding VOCAB_FEATURES by tf.transform
VOCAB_SIZE = 1000
# Count of out-of-vocab buckets in which unrecognized VOCAB_FEATURES are hashed.
OOV_SIZE = 10
VOCAB_FEATURE_KEYS = [
'payment_type',
'company',
]
# Keys
LABEL_KEY = 'tips'
FARE_KEY = 'fare'
Writing taxi_constants.py
Далее мы пишем preprocessing_fn , который принимает в необработанных данных в качестве входных данных и возвращает трансформированных функции , что наша модель может тренироваться на:

Рассмотрим выходные артефакты Transform . Этот компонент производит два типа выходных данных:
-
transform_graphявляется графиком , который может выполнять предварительную обработку операций (этот график будет включен в моделях обслуживающих и оценки). -
transformed_examplesпредставляет препроцессированные данные обучения и оценки.

Взгляните на transform_graph артефакт. Он указывает на каталог, содержащий три подкаталога.
train_uri = transform.outputs['transform_graph'].get()[0].uri
os.listdir(train_uri)
['transform_fn', 'transformed_metadata', 'metadata']
transformed_metadata подкаталог содержит схему препроцессированных данных. transform_fn подкаталог содержит фактический график предварительной обработки. metadata подкаталог содержит схему исходных данных.
Мы также можем взглянуть на первые три преобразованных примера:
# Get the URI of the output artifact representing the transformed examples, which is a directory
train_uri = os.path.join(transform.outputs['transformed_examples'].get()[0].uri, 'Split-train')
# Get the list of files in this directory (all compressed TFRecord files)
tfrecord_filenames = [os.path.join(train_uri, name)
for name in os.listdir(train_uri)]
# Create a `TFRecordDataset` to read these files
dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")
# Iterate over the first 3 records and decode them.
for tfrecord in dataset.take(3):
serialized_example = tfrecord.numpy()
example = tf.train.Example()
example.ParseFromString(serialized_example)

После Transform компонент преобразовал данные в особенности, и следующим шагом является подготовка модели.
Тренер
Trainer компонент будет тренировать модель , которую вы определяете в TensorFlow (либо с помощью API оценщика или API Keras с model_to_estimator ).
Trainer принимает в качестве входных данных в схему из SchemaGen , преобразованные данные и график из Transform , обучение, параметры, а также модуль , который содержит определенный пользователем код модели.
Давайте рассмотрим пример пользовательского кода модели ниже (для введения в TensorFlow Оценщик APIs, можно найти в учебнике ):

Анализируйте обучение с помощью TensorBoard
При желании мы можем подключить TensorBoard к Trainer, чтобы анализировать кривые обучения нашей модели.
# Get the URI of the output artifact representing the training logs, which is a directory

Оценщик
Evaluator компонент вычисляет модели метрик производительности по сравнению с набором оценки. Он использует TensorFlow модель анализа библиотеки. Evaluator может также дополнительно подтвердить , что недавно обучен модель лучше , чем у предыдущей модели. Это полезно при настройке производственного конвейера, где вы можете автоматически обучать и проверять модель каждый день. В этом ноутбуке, мы только обучить одну модель, поэтому Evaluator автоматически помечает модель как «хорошее».
Evaluator будет принимать в качестве входных данных из ExampleGen , обученной модели от Trainer и конфигурации нарезки. Конфигурация срезов позволяет вам срезать ваши метрики по значениям характеристик (например, как ваша модель работает в поездках на такси, которые начинаются в 8 утра по сравнению с 8 вечера?). См. Пример этой конфигурации ниже:

metrics_specs=[

Используя evaluation вывода мы можем показать визуализацию по умолчанию глобальных показателей по всей совокупности оценок.
context.show(evaluator.outputs['evaluation'])
Чтобы увидеть визуализацию срезов показателей оценки, мы можем напрямую вызвать библиотеку анализа модели TensorFlow.
import tensorflow_model_analysis as tfma
# Get the TFMA output result path and load the result.
PATH_TO_RESULT = evaluator.outputs['evaluation'].get()[0].uri
tfma_result = tfma.load_eval_result(PATH_TO_RESULT)
# Show data sliced along feature column trip_start_hour.
tfma.view.render_slicing_metrics(
tfma_result, slicing_column='trip_start_hour')
SlicingMetricsViewer(config={'weightedExamplesColumn': 'example_count'}, data=[{'slice': 'trip_start_hour:19',…
Эта визуализация показывает те же показатели, но вычисляется на каждом значении признака trip_start_hour , а не на всей совокупности оценки.
TensorFlow Model Analysis поддерживает множество других визуализаций, таких как индикаторы справедливости и построение временных рядов производительности модели. Чтобы узнать больше, см учебник .
Поскольку мы добавили пороги в нашу конфигурацию, также доступен вывод проверки. Precence из blessing артефакта указывает , что наша модель прошла проверку. Поскольку это первая проверка, кандидат автоматически получает благословение.
blessing_uri = evaluator.outputs['blessing'].get()[0].uri
!ls -l {blessing_uri}
total 0 -rw-rw-r-- 1 kbuilder kbuilder 0 Dec 5 11:03 BLESSED
Теперь также можно проверить успешность, загрузив запись результата проверки:
PATH_TO_RESULT = evaluator.outputs['evaluation'].get()[0].uri
print(tfma.load_validation_result(PATH_TO_RESULT))
validation_ok: true
validation_details {
slicing_details {
slicing_spec {
}
num_matching_slices: 25
}
}
Толкатель
Pusher компонент, как правило , в конце TFX трубопровода. Он проверяет, является ли модель прошла проверку, и если да, экспорт модели в _serving_model_dir .

model=trainer.outputs['model'],
model_blessing=evaluator.outputs['blessing'],
push_destination=tfx.proto.PushDestination(
filesystem=tfx.proto.PushDestination.Filesystem(
base_directory=_serving_model_dir)))

В частности, Pusher экспортирует вашу модель в формате SavedModel, который выглядит так:
push_uri = pusher.outputs['pushed_model'].get()[0].uri
model = tf.saved_model.load(push_uri)
for item in model.signatures.items():
pp.pprint(item)
('regression', <ConcreteFunction pruned(inputs) at 0x7F19BF0F9510>)
('classification', <ConcreteFunction pruned(inputs) at 0x7F19BE0EC350>)

('predict', <ConcreteFunction pruned(examples) at 0x7F19BC4F9090>)
