ペンギンデータセットを使用した簡単なTFXパイプラインチュートリアル

コレクションでコンテンツを整理 必要に応じて、コンテンツの保存と分類を行います。

簡単なTFXパイプラインを実行するための短いチュートリアル。

このノートブックベースのチュートリアルでは、単純な分類モデルのTFXパイプラインを作成して実行します。パイプラインは、ExampleGen、Trainer、Pusherの3つの重要なTFXコンポーネントで構成されます。パイプラインには、データのインポート、モデルのトレーニング、トレーニングされたモデルのエクスポートなど、最小限のMLワークフローが含まれています。

参照してくださいTFXパイプラインが理解TFXの様々な概念についての詳細を学ぶために。

設定

まず、TFX Pythonパッケージをインストールし、モデルに使用するデータセットをダウンロードする必要があります。

アップグレードピップ

ローカルで実行しているときにシステムでPipをアップグレードしないようにするには、Colabで実行していることを確認してください。もちろん、ローカルシステムは個別にアップグレードできます。

try:
  import colab
  !pip install --upgrade pip
except:
  pass

TFXをインストールする

pip install -U tfx

ランタイムを再起動しましたか?

上記のセルを初めて実行するときにGoogleColabを使用している場合は、[ランタイムの再起動]ボタンをクリックするか、[ランタイム]> [ランタイムの再起動...]メニューを使用してランタイムを再起動する必要があります。これは、Colabがパッケージをロードする方法が原因です。

TensorFlowとTFXのバージョンを確認してください。

import tensorflow as tf
print('TensorFlow version: {}'.format(tf.__version__))
from tfx import v1 as tfx
print('TFX version: {}'.format(tfx.__version__))
TensorFlow version: 2.6.2
TFX version: 1.4.0

変数を設定する

パイプラインを定義するために使用されるいくつかの変数があります。これらの変数は必要に応じてカスタマイズできます。デフォルトでは、パイプラインからのすべての出力は現在のディレクトリの下に生成されます。

import os

PIPELINE_NAME = "penguin-simple"

# Output directory to store artifacts generated from the pipeline.
PIPELINE_ROOT = os.path.join('pipelines', PIPELINE_NAME)
# Path to a SQLite DB file to use as an MLMD storage.
METADATA_PATH = os.path.join('metadata', PIPELINE_NAME, 'metadata.db')
# Output directory where created models from the pipeline will be exported.
SERVING_MODEL_DIR = os.path.join('serving_model', PIPELINE_NAME)

from absl import logging
logging.set_verbosity(logging.INFO)  # Set default logging level.

サンプルデータを準備する

TFXパイプラインで使用するサンプルデータセットをダウンロードします。私たちが使用しているデータセットがあるパーマーペンギンデータセットも他で使用されているTFX例

このデータセットには、次の4つの数値機能があります。

  • culmen_length_mm
  • culmen_depth_mm
  • フリッパー_長さ_mm
  • body_mass_g

すべての特徴は、範囲[0,1]を持つようにすでに正規化されています。私たちは、予測、分類モデル構築するspeciesのペンギンのを。

TFX ExampleGenはディレクトリから入力を読み取るため、ディレクトリを作成してデータセットをそこにコピーする必要があります。

import urllib.request
import tempfile

DATA_ROOT = tempfile.mkdtemp(prefix='tfx-data')  # Create a temporary directory.
_data_url = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/penguin/data/labelled/penguins_processed.csv'
_data_filepath = os.path.join(DATA_ROOT, "data.csv")
urllib.request.urlretrieve(_data_url, _data_filepath)
('/tmp/tfx-dataijanq9u3/data.csv', <http.client.HTTPMessage at 0x7f487953d110>)

CSVファイルをざっと見てみましょう。

5つの値が表示されるはずです。 species 0、1または2のいずれか、およびすべての他の特徴は0と1の間の値を有するべきです。

パイプラインを作成する

TFXパイプラインは、PythonAPIを使用して定義されます。次の3つのコンポーネントで構成されるパイプラインを定義します。

  • CsvExampleGen:データファイルを読み込み、さらに処理するためにTFX内部形式に変換します。複数ありますExampleGen様々なフォーマットのためのsが。このチュートリアルでは、CSVファイル入力を受け取るCsvExampleGenを使用します。
  • トレーナー:MLモデルをトレーニングします。トレーナーコンポーネントは、ユーザーからのモデル定義のコードが必要です。あなたは、モデルを訓練し、_savedモデル形式で保存する方法を指定するTensorFlow APIを使用することができます。
  • プッシャー:トレーニング済みモデルをTFXパイプラインの外部にコピーします。プッシャーコンポーネントは、訓練されたMLモデルの展開過程と考えることができます。

実際にパイプラインを定義する前に、まずトレーナーコンポーネントのモデルコードを作成する必要があります。

モデルトレーニングコードを書く

TensorFlow KerasAPIを使用して分類するための単純なDNNモデルを作成します。このモデルトレーニングコードは別のファイルに保存されます。

このチュートリアルでは、使用する一般的なトレーナーKerasベースのモデルをサポートTFXの。あなたは含むPythonのファイル記述する必要がrun_fnためのエントリポイントである機能、 Trainerコンポーネントを。

パイプラインを実行する

TFXは、パイプラインを実行するための複数のオーケストレーターをサポートしています。このチュートリアルでは、使用するLocalDagRunnerローカル環境にTFX Pythonパッケージおよび実行パイプラインに含まれています。有向非巡回グラフを表すTFXパイプラインを「DAG」と呼ぶことがよくあります。

LocalDagRunner developemntとデバッグのための高速反復を提供します。 TFXは、KubeflowPipelinesやApacheAirflowなど、本番ユースケースに適した他のオーケストレーターもサポートしています。

参照クラウドAIプラットフォームパイプライン上のTFXTFXエアフローチュートリアルが他のオーケストレーションシステムについて詳しく学ぶこと。

今、私たちは、作成LocalDagRunnerして渡すPipeline我々はすでに定義された関数から作成されたオブジェクトを。
