배경
이 노트북은 Jupyter/Colab 환경에서 MLMD 및 TFX 파이프라인이 있는 Model Card Toolkit을 사용하여 모델 카드를 생성하는 방법을 보여줍니다. 당신은에서 모델 카드에 대해 자세히 알아볼 수 있습니다 https://modelcards.withgoogle.com/about
설정
먼저) 필요한 패키지를 설치 및 가져오고, b) 데이터를 다운로드해야 합니다.
Pip 20.2로 업그레이드하고 TFX 설치
pip install -q --upgrade pip==20.2pip install -q "tfx==0.26.0"pip install -q model-card-toolkit
런타임을 다시 시작하셨습니까?
Google Colab을 사용하는 경우 위의 셀을 처음 실행할 때 런타임을 다시 시작해야 합니다(런타임 > 런타임 다시 시작...). Colab이 패키지를 로드하는 방식 때문입니다.
패키지 가져오기
표준 TFX 구성 요소 클래스를 포함하여 필요한 패키지를 가져오고 라이브러리 버전을 확인합니다.

WARNING:tensorflow:5 out of the last 5 calls to <function recreate_function.<locals>.restored_function_body at 0x7f77a02d2510> triggered tf.function retracing. Tracing is expensive and the excessive number of tracings could be due to (1) creating @tf.function repeatedly in a loop, (2) passing tensors with different shapes, (3) passing Python objects instead of tensors. For (1), please define your @tf.function outside of the loop. For (2), @tf.function has experimental_relax_shapes=True option that relaxes argument shapes that can avoid unnecessary retracing.
