pycharm执行图像操作时出现Qt platform错误，发现

`
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Reinstalling the application may fix this problem.

解决方案，如果你安装了anaconda,或者miniconda，找到所在文件夹下的library\plugins的plantforms文件夹，将他复制到G:\Anaconda2.7下，也就是和python.exe同一目录下即可。
G:\Anaconda2.7\Library\plugins
