Original error was: No module named 'numpy.core._multiarray_umath'

 

원인

원인은 완전히는 모르겠는데 이것저것 설치하면서 원래 파이썬3.11 경로쪽의 numpy를 찾고 있는거 같다.

 

해결방법

해결방법은 의외로 간단하다.

numpy과 setuptools 를 지우고 다시 설치하면 해결 된다.

(setuptools 는 python 라이브러리 관리하는데 사용되는 라이브러리)

pip uninstall -y numpy
pip uninstall -y setuptools

pip install setuptools
pip install numpy
