Ubuntu18.04同时配置python3-opencv和python2-opencv

1.先为python2配置opencv和opencv-contrib

pip install opencv-python
pip install opencv-contrib-python

2.再为python3配置opencv和opencv-contrib

pip3 install opencv
pip3 install opencv-contrib-python

问题：在为python3配置opencv和contrib的时候总是报错：

解决：

先删除 home/zhoujie/.local/lib/python3.6/site-packages/ 中的numpy包和matplotlib包，再重新安装

怎么进“.”开头的隐藏文件夹呢？

右边那个显示隐藏文件夹打钩就可以

手动删除numpy包和matplot包，没有就不删

安装numpy和matplot包：

pip3 install numpy
pip3 install matplotlib

再安装python3-opencv

pip3 install opencv-python
pip3 install opencv-contrib-python

3.测试

python3.6 成功

python2.7 成功
