Migrate TensorBoard:TensorFlowの視覚化ツールキット

TensorFlow.orgで表示 GoogleColabで実行 GitHubでソースを表示 ノートブックをダウンロード

TensorBoardはビルトインツールTensorFlowでの測定と可視化を提供するためのものです。精度や損失などの一般的な機械学習実験の指標は、TensorBoardで追跡および表示できます。 TensorBoardは、TensorFlow1および2コードと互換性があります。

TensorFlow 1では、 tf.estimator.EstimatorデフォルトでTensorBoardのための要約を保存します。比較では、TensorFlow 2に、要約を使用して保存することができtf.keras.callbacks.TensorBoardコールバックを

このガイドでは、最初にTensorFlow 1でEstimatorsを使用してTensorBoardを使用する方法を示し、次にTensorFlow2で同等のプロセスを実行する方法を示します。
