텐서플로우 설치 후, 다음과 같은 경고 메세지가 뜨는 경우가 있다.

기존에는 [(name, dtype, 1)] 또는 "1type"이 스칼라 타입, 즉 [(name, dtype)] 또는 [(name, dtype, ())] 으로 다루어졌지만, 1.17 버전에서는 [(name, dtype, (1,))] 또는 "(1,)type"으로 취급된다는 경고메세지이다.
이 경고메세지와 관련해서는 다음 링크에서 확인할 수 있다.

https://docs.scipy.org/doc/numpy/release.html#future-changes 

기존에 설치되어 있던 numpy 버전이 1.17이상이라면 설치되어 있는 numpy를 제거하고 1.17 아래 버전으로 재설치하면 문제가 해결된다.

$ pip install "numpy<1.17"
