OpenCV 安装：弃用错误

Question

我想在 python 中使用 opencv，但我认为我的 numpy 版本有问题。 如何确保 opencv 使用正确的 numpy 版本？

我做了

sudo pip install opencv-python

我收到了这条消息

Installing collected packages: numpy, opencv-python
Found existing installation: numpy 1.8.0rc1
DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
Uninstalling numpy-1.8.0rc1:
  Successfully uninstalled numpy-1.8.0rc1
Successfully installed numpy-1.14.5 opencv-python-3.4.1.15

现在当我尝试

import cv2

我得到

ImportError: numpy.core.multiarray failed to import

我还更新了我的 numpy 版本

sudo pip install -U numpy

如果您在机器上同时使用 Py2.7 和 3.5，请通过执行python3 -m pip install numpy -I或python2 -m pip install numpy -I来确保安装了正确版本的python2 -m pip install numpy -I
