qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/lbw/anaconda3/envs/uniad/lib/python3.8/site-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.
