安装cv2

pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple

ImportError: libSM.so.6: cannot open shared object file: No such file or directory

退出虚拟环境，在ubuntu下使用命令

i686是32位系统我们的是64位系统所以用x86_64

yum whatprovides libSM.so.6

yum install libSM-1.2.2-2.el7.x86_64 --setopt=protected_multilib=false

ImportError: libXrender.so.1: cannot open shared object file: No such file or directory

yum whatprovides libXrender.so.1

yum install libXrender-0.9.10-1.el7.x86_64 --setopt=protected_multilib=false

ImportError: libXext.so.6: cannot open shared object file: No such file or directory

yum whatprovides libXext.so.6

yum install libXext-1.3.3-3.el7.x86_64 --setopt=protected_multilib=false

至此能够完美运行
