having trouble with UI "qt.qpa.plugin issue"

[jakeyahn]

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/student/anaconda3/envs/sean_env/lib/python3.7/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.

any suggestion?

all the other pretrained model works fine!
currently using ubuntu server from VScode

I guess you use the VSCode to connect the remote Ubuntu Server. This issue is probably due to no display screen or UI client can be found on the server.

So. To run the UI program, you might have to install the Qt-related packages on your local machine.

Could you please explain in detail which packages you need? I've been working on it for a while

installing python-opencv-headless might solve your problem.
