ノートブックをダウンロード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ます。このパイプラインは、単純な分類モデルを作成し、複数の実行にわたるパフォーマンスを分析します。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いますシンプルなTFXパイプラインのチュートリアル。そのチュートリアルを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。
モデルを微調整したり、新しいデータセットでトレーニングしたりするときは、モデルが改善されたか、悪化したかを確認する必要があります。精度などのトップレベルのメトリックをチェックするだけでは不十分な場合があります。トレーニングされたすべてのモデルは、本番環境にプッシュする前に評価する必要があります。
私たちは、追加されますEvaluator前のチュートリアルで作成したパイプラインにコンポーネントを。 Evaluatorコンポーネントは、モデルの詳細な分析を実行し、新しいモデルをベースラインと比較して、モデルが「十分」であるかどうかを判断します。これは、使用して実装されTensorFlowモデル解析ライブラリを。
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
セットアッププロセスは、前のチュートリアルと同じです。
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-tfma"
# 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
私たちは、同じ使用しますパーマーペンギンデータセットを。
このデータセットには、範囲[0,1]を持つようにすでに正規化されている4つの数値特徴があります。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。

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'

urllib.request.urlretrieve(_data_url, _data_filepath)
('/tmp/tfx-datal5lxy_yw/data.csv', <http.client.HTTPMessage at 0x7fa18a9da150>)
パイプラインを作成する
私たちは、追加されますEvaluator私たちが作成したパイプラインに部品をシンプルTFXパイプラインのチュートリアル。
ANエバリュエータコンポーネントからの入力データを必要とExampleGen成分とからモデルTrainer成分とtfma.EvalConfigオブジェクト。オプションで、メトリックを新しくトレーニングされたモデルと比較するために使用できるベースラインモデルを提供できます。
評価者は、出力成果物の2種類作成しModelEvaluationとModelBlessing 。 ModelEvaluationには、TFMAライブラリを使用してさらに調査および視覚化できる詳細な評価結果が含まれています。 ModelBlessingには、モデルが特定の基準に合格したかどうかのブール結果が含まれており、プッシャーなどの後のコンポーネントで信号として使用できます。

私たちは、経由して評価者に以下の情報を提供する必要がありeval_config ：
- 構成する追加のメトリック（モデルで定義されているよりも多くのメトリックが必要な場合）。
- 構成するスライス
- 検証が含まれるかどうかを検証するためのモデル検証しきい値
のでSparseCategoricalAccuracyすでに含まれていたmodel.compile()呼び出し、それが自動的に分析に含まれます。したがって、ここではメトリックを追加しません。 SparseCategoricalAccuracyモデルがあまりにも、良い十分であるかどうかを決定するために使用されます。
データセット全体と各ペンギン種の指標を計算します。 SlicingSpec私たちが宣言したメトリックを集約方法を指定します。
新しいモデルが通過する必要がある2つのしきい値があります。1つは0.6の絶対しきい値であり、もう1つはベースラインモデルよりも高くなければならない相対しきい値です。初めてのパイプラインを実行すると、 change_threshold無視され、唯一のvalue_thresholdがチェックされます。あなたが複数回パイプラインを実行すると、 Resolver前回の実行からモデルを見つけるだろうし、それは比較のためのベースラインモデルとして使用されます。

パイプラインの出力を調べます
TFMAを使用して、ModelEvaluationアーティファクトの評価結果を調査および視覚化できます。
出力アーティファクトから分析結果を取得する
MLMD APIを使用して、これらの出力をプログラムで見つけることができます。最初に、生成されたばかりの出力アーティファクトを検索するためのいくつかの効用関数を定義します。
from ml_metadata.proto import metadata_store_pb2
# Non-public APIs, just for showcase.
from tfx.orchestration.portable.mlmd import execution_lib
# TODO(b/171447278): Move these functions into the TFX library.
def get_latest_artifacts(metadata, pipeline_name, component_id):
"""Output artifacts of the latest run of the component."""
context = metadata.store.get_context_by_type_and_name(
'node', f'{pipeline_name}.{component_id}')
executions = metadata.store.get_executions_by_context(context.id)
latest_execution = max(executions,
key=lambda e:e.last_update_time_since_epoch)
return execution_lib.get_artifacts_dict(metadata, latest_execution.id,
[metadata_store_pb2.Event.OUTPUT])
私たちは、最新の実行を見つけることができますEvaluatorコンポーネントを、それの出力アーティファクトを取得します。
# Non-public APIs, just for showcase.
from tfx.orchestration.metadata import Metadata
from tfx.types import standard_component_specs
metadata_connection_config = tfx.orchestration.metadata.sqlite_metadata_connection_config(
METADATA_PATH)
with Metadata(metadata_connection_config) as metadata_handler:
# Find output artifacts from MLMD.
evaluator_output = get_latest_artifacts(metadata_handler, PIPELINE_NAME,
'Evaluator')
eval_artifact = evaluator_output[standard_component_specs.EVALUATION_KEY][0]

Evaluator 、常に1つの評価アーティファクトを返し、私たちはTensorFlowモデル解析ライブラリを使用して、それを可視化することができます。たとえば、次のコードは、各ペンギン種の精度メトリックをレンダリングします。
import tensorflow_model_analysis as tfma
eval_result = tfma.load_eval_result(eval_artifact.uri)
tfma.view.render_slicing_metrics(eval_result, slicing_column='species')
SlicingMetricsViewer(config={'weightedExamplesColumn': 'example_count'}, data=[{'slice': 'species:0', 'metrics…
あなたが「sparse_categorical_accuracy」を選択した場合はShowドロップダウンリストには、種ごとの精度の値を見ることができます。さらにスライスを追加して、モデルがすべての分布に適しているかどうか、およびバイアスの可能性があるかどうかを確認することをお勧めします。
