TFXパイプラインとTensorFlow変換を使用した機能エンジニアリング

入力データを変換し、TFXパイプラインを使用してモデルをトレースします。

このノートブックベースのチュートリアルでは、TFXパイプラインを作成して実行し、生の入力データを取り込んで、MLトレーニング用に適切に前処理します。このノートブックは、私たちが組み込まTFXパイプラインに基づいておりTFXパイプラインとTensorFlowデータ検証のチュートリアルを使用したデータの検証。まだ読んでいない場合は、このノートブックに進む前に読んでください。

特徴エンジニアリングを使用すると、データの予測品質を向上させたり、次元を削減したりできます。 TFXを使用する利点の1つは、変換コードを1回記述することです。結果として得られる変換は、トレーニングとサービングのスキューを回避するために、トレーニングとサービングの間で一貫性があります。

私たちは、追加するTransformパイプラインに部品。変換コンポーネントを使用して実装されてtf.transformのライブラリを。

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-transform"

# 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セット

しかし、すでに前処理データセットを使用し、前のチュートリアルとは異なり、我々はパーマーペンギンのデータセットを使用します。

TFX ExampleGenコンポーネント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_path = 'https://storage.googleapis.com/download.tensorflow.org/data/palmer_penguins/penguins_size.csv'
_data_filepath = os.path.join(DATA_ROOT, "data.csv")
urllib.request.urlretrieve(_data_path, _data_filepath)
('/tmp/tfx-dataacmxfq9f/data.csv', <http.client.HTTPMessage at 0x7f5b0ab1bf10>)

生データがどのように見えるかを簡単に見てみましょう。

head {_data_filepath}

Adelie,Torgersen,39.2,19.6,195,4675,MALE

表現されている欠損値を持ついくつかのエントリがありNA 。このチュートリアルでは、これらのエントリを削除します。

Adelie,Torgersen,41.1,17.6,182,3200,FEMALE
Adelie,Torgersen,38.6,21.2,191,3800,MALE

あなたはペンギンを説明する7つの特徴を見ることができるはずです。前のチュートリアルと同じ機能セット( 'culmen_length_mm'、 'culmen_depth_mm'、 'flipper_length_mm'、 'body_mass_g')を使用し、ペンギンの '種'を予測します。

唯一の違いは、入力データが前処理されていないことです。このチュートリアルでは、「島」や「性別」などの他の機能は使用しないことに注意してください。

スキーマファイルを準備する

で説明したようにTFXパイプラインとTensorFlowデータ検証のチュートリアルを使用したデータの検証、我々は、データセットのスキーマファイルを必要とします。データセットは前のチュートリアルとは異なるため、再度生成する必要があります。このチュートリアルでは、これらの手順をスキップして、準備されたスキーマファイルを使用します。

import shutil

SCHEMA_PATH = 'schema'

_schema_uri = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/penguin/schema/raw/schema.pbtxt'
_schema_filename = 'schema.pbtxt'
_schema_filepath = os.path.join(SCHEMA_PATH, _schema_filename)

os.makedirs(SCHEMA_PATH, exist_ok=True)
urllib.request.urlretrieve(_schema_uri, _schema_filepath)
('schema/schema.pbtxt', <http.client.HTTPMessage at 0x7f5b0ab20f50>)

このスキーマファイルは、手動で変更することなく、前のチュートリアルと同じパイプラインで作成されました。

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。私たちは、追加されますTransform私たちが作成したパイプラインにコンポーネントをデータ検証のチュートリアル

Aは、成分を変換からの入力データを必要とExampleGen成分とからスキーマSchemaGen成分、及び「グラフ変換」を生成します。出力はで使用されるTrainerコンポーネント。 Transformは、オプションで「変換されたデータ」を生成できます。これは、変換後のマテリアライズされたデータです。ただし、このチュートリアルでは、中間変換データを具体化せずに、トレーニング中にデータを変換します。

もう一つ注意すべきは、我々は、Pythonの関数を定義する必要があるということですpreprocessing_fn変換する方法を入力データを説明するために。これは、モデル定義にユーザーコードを必要とするTrainerコンポーネントに似ています。

前処理とトレーニングコードを書く

2つのPython関数を定義する必要があります。 1つは変換用、もう1つはトレーナー用です。

preprocessing_fn

変換コンポーネントは、指定された関数を見つけるでしょうpreprocessing_fn我々が行ったように与えられたモジュールファイルにTrainerコンポーネント。また、使用して、特定の関数を指定することができますpreprocessing_fnパラメータ変換コンポーネントのを。

この例では、2種類の変換を行います。以下のような連続する数値の機能についてculmen_length_mmbody_mass_g 、我々は使用して、これらの値を正規化しますtft.scale_to_z_scoreの機能を。ラベル機能の場合、文字列ラベルを数値のインデックス値に変換する必要があります。私たちは、使用するtf.lookup.StaticHashTable変換するために。

簡単に変換フィールドを識別するために、我々は追加_xf変換機能名に接尾辞。

run_fn

モデル自体は前のチュートリアルとほぼ同じですが、今回はTransformコンポーネントの変換グラフを使用して入力データを変換します。

前のチュートリアルとのもう1つの重要な違いは、モデルの計算グラフだけでなく、変換コンポーネントで生成される前処理の変換グラフも含む、サービング用のモデルをエクスポートすることです。着信要求を処理するために使用される別の関数を定義する必要があります。あなたは、同じ機能のことを見ることができます_apply_preprocessingトレーニングデータとサービス提供要求の両方のために使用されました。

また、使用して生成されたモデルの署名を確認することができsaved_model_cliツールを

saved_model_cli show --dir {SERVING_MODEL_DIR}/$(ls -1 {SERVING_MODEL_DIR} | sort -nr | head -1) --tag_set serve --signature_def serving_default
The given SavedModel SignatureDef contains the following input(s):
  inputs['examples'] tensor_info:
      dtype: DT_STRING
      shape: (-1)
      name: serving_default_examples:0
The given SavedModel SignatureDef contains the following output(s):
  outputs['output_0'] tensor_info:
      dtype: DT_FLOAT
      shape: (-1, 3)
      name: StatefulPartitionedCall_2:0
Method name is: tensorflow/serving/predict
