구름IDE 파이썬,tensorflow 이미지 바로 볼수 있는 창 문의
-
지금 tensorflow 에서 Object detection 보고 따라 하고 있는데 코랩에서 하는 거는 바로바로 이미지가 뜨는데 구름IDE로 하려면 작업이 안되거나(죽었다 라고표시됨) 되더라도 결과값을 확인이 안됩니다. ```

@최해선
Jupyter notebook 통해서 실행을 하시면 결과 이미지를 바로 확인하실 수 있습니다 -
@Jose-goorm 그러면 이미지는 어떻게 확인할수있는 방법이 있습니까?
-
줄넘김은 아래와 같이 시도해보시기 바랍니다
str1 = "abcd"\ "efgh" str2 = ("가나다라" "마바사아" )
-
matplotlib 결과 이미지 표시는 현재 지원되지 않고 있습니다.
Jupyter notebook 스택으로 컨테이너 생성하셔서 한번 시도해보시는 것도 추천 드립니다. -
내용이 보기 힘든데 허브 에디터 문제일까요?ㅜ
-
추가적으로 줄넘김 \ 하는 저 방법이 맞는지 알려주시면 감사합니다
