[nuri428]

예제로 있는 fashion-mnist-fairing.ipynb 파일을 실행 시키면 아래와 같은 오류가 발생 합니다.

해당 내용은 제가 Jupyter Lab을 이용해서 발생한 문제네요 전처리 모듈이 JupyterLab을 통해서 ipynb 파일을 가져오지 못하고 있고 다른 방법이 없어서 코드를 일부 수정 해야합니다.

fairing.config.set_builder( 'append', image_name='fairing-job', base_image='brightfly/kubeflow-jupyter-lab:tf2.0-gpu', registry=DOCKER_REGISTRY,
push=True)

    # 원래 예제 코드에서 아래에 이 코드를 추가 하면 됩니다.

    # notebook_file : ipynb 파일명

    # cpu 2, memory 5GiB
