일단 위의 메시지는 에러가 아닌 경고 메시지이다. 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 경고메시지이다. 이와 관련된 내용은 다음 링크에서 찾아볼 수 있다.

기존에 설치되어 있던 1.17.2 버전을 제거하고 1.16.5 버전을 설치했다.

(AnnaM) founder@hilbert:~$ pip install "numpy<1.17"

다시 텐서플로우를 실행해보면 정상적으로 라이브러리를 불러옴을 알 수 있다.
