导入cv2非法值，无法导入

Question

我使用的是带有pip版本20.3.1 的Python 3.9.0

我已经使用pip install opencv-python成功安装了numpy-1.19.4 opencv-python-4.0.46

然而，当我运行import cv2时，会出现无数错误

我已经重新安装了python/nympy&openCV

我尝试了pip install -U numpy以修复`ImportError:numpy.core.multirarray无法导入

Answer 1

安装以前版本的numpy，1.19.3应该可以解决这个问题。python -m pip install numpy==1.19.3
