성의있는 답변 고맙습니다. 되도록 혼자 해결하려고 노력하는데 안되는 군요.&nbsp;
선생님의 말씀대로 시도했으나&nbsp; 다음과 같은 결과가 나왔습니다.
물론 anaconda3를 삭제했고, pip 이나 conda를 이용해서 tensorflow를 모두 삭제하고
python 3.7.7
tensorflow 2.2.0(cpu)
numpy 1.19.3을 새로 깔았습니다.

이전에 깐 tensorflow를 전부 삭제 한다고 했는데 덜 삭제 되었나 싶기도 하고 ...
매번 죄송합니다.

어떻게 해야 하나요?
아! 참, 이런 환경이 되니까 jupyter notebook도 실행이 안되고 다음과 같은 error가 나더라구요.
