Opencv不导入

Question

当我尝试运行命令时

import cv2

我不断收到错误消息

  File "C:\Users\joshu\AppData\Local\Programs\Python\Python37-32\lib\numpy\core\__init__.py", line 17, in <module>
    from . import multiarray
  File "C:\Users\joshu\AppData\Local\Programs\Python\Python37-32\lib\numpy\core\multiarray.py", line 14, in <module>
    from . import overrides
  File "C:\Users\joshu\AppData\Local\Programs\Python\Python37-32\lib\numpy\core\overrides.py", line 7, in <module>
    from numpy.core._multiarray_umath import (
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'

我尝试重新安装python本身，pip，numpy和opencv，但似乎没有任何效果。我正在寻找类似的问题，但唯一的答案就是我的问题。
