在opencv安装后在Python中导入cv2时出错

Question

我已经成功安装了OpenCV，但是当我尝试将其导入Python时，出现以下错误。

在Python 2.7中，我得到了

[imukunya@li165-244 site-packages]$ python

Python 2.7.5 (default, Oct 30 2018, 23:45:53)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-36)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> import cv2
>>> ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: numpy.core.multiarray failed to import

在Python 3.6中，出现此错误

[imukunya@li165-244 site-packages]$ python3.6

Python 3.6.5 (default, Apr 10 2018, 17:08:37)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux

>>> import cv2

>>> Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dynamic module does not define module export function (PyInit_cv2)

我已经尝试使用$~python3 -m pip install numpy -I安装NumPy
