Question

我想将opencv与python一起使用，但我认为我的numpy版本存在问题。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

现在我尝试

import cv2

我得到了

ImportError: numpy.core.multiarray failed to import

我还用

更新了我的numpy版本

sudo pip install -U numpy

Answer 1

如果您在计算机上同时使用Py2.7和3.5，请确保通过python3 -m pip install numpy -I执行任何正确版本的numpy 或python2 -m pip install numpy -I

OpenCV安装：弃用错误
