今天在运行代码的时候出现了以下错误，经查找资料，找到了解决方法。

错误如下：

QFactoryLoader::QFactoryLoader() checking directory path "/usr/bin/platforms" ...
Cannot load library /usr/local/lib/python3.6/dist-packages/cv2/qt/plugins/platforms/libqxcb.so: (libSM.so.6: cannot open shared object file: No such file or directory)
QLibraryPrivate::loadPlugin failed on "/usr/local/lib/python3.6/dist-packages/cv2/qt/plugins/platforms/libqxcb.so" : "Cannot load library /usr/local/lib/python3.6/dist-packages/cv2/qt/plugins/platforms/libqxcb.so: (libSM.so.6: cannot open shared object file: No such file or directory)"
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/local/lib/python3.6/dist-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.
