qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/notebooks/miniconda3/envs/openseeface/lib/python3.9/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.
Available platform plugins are: xcb.
It's not an OpenSeeFace specific issue, but looks like a problem with your OpenCV installation. It tries to use the Qt library to open a window, but it cannot find the necessary library.
hi, anyone know how to fix this error? thanks!
