1. train부분 에러 train_isbi_2012.py:177: UserWarning: Model.fit_generator is deprecated and will be removed in a future version. Please use Model.fit, which supports generators. 이거를 Model.fit로 바꿔야하나요?

안녕하세요 말하신데로 train evaluate 다바꿔서 5장 저장다하고 ckpt 로 교체해서 evaluate_isbi_2012.py 실행하니 이런문제가 뜨네요.감사합니다

안녕하세요~. 반갑습니다.

먼저 수강에 불편을 드려서 죄송합니다ㅠ.

해당 부분 관련해서 예전에 답변을 드렸던 내용이 있는데요.

https://www.inflearn.com/questions/687532/evaluate-isbi-2012-py-%EC%8B%A4%ED%96%89%EA%B4%80%EB%A0%A8-%EB%AC%B8%EC%9D%98%EB%93%9C%EB%A6%BD%EB%8B%88%EB%8B%A4

위에 내용을 정리하면 train_isbi_2012.py 파일과 evaluate_isbi_2012.py 파일들을 아래 파일들로 교체해서 실행해보시겠어요?

https://gist.github.com/solaris33/64feceb48079a2b339ef9f18a6544a74
https://gist.github.com/solaris33/771639041b8a4500b6d81951d4a2b814

첨부해주신 에러내용으로 추론해보면 현재 .pb 파일로 저장하도록 train_isbi_2012.py 파일을 수정했는데 evaluate_isbi_2012.py 파일에서는 .ckpt 파일을 불러오도록 수정해서 문제가 발생한것 같습니다.

위에 gist 파일들로 교체하시면 train_isbi_2012.py과 evaluate_isbi_2012.py 파일에서 모두 .ckpt 파일을 사용하게 됩니다.

해보시고 혹시 문제 있으면 다시 질문 주세요.

좋은하루 되세요.

감사합니다.
