docker python cv2.imshow xcb

글을 찾아보는데 대부분이 Xwin 시절의 내용이라

죄다 X로 돌리는건데.. wayland 쓰는 환경이라 안되서 이래저래 멘붕중

>>> cv2.imshow("tt",img) qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "/usr/local/lib/python3.12/site-packages/cv2/qt/plugins" 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.

 

 

opencv headless 를 설치하면 된다는데

$ pip install opencv-python-headless

막상해보면 not implemented 라고 나오면서 실행이 안될뿐이고 (머.. xcb 에러를 안 뱉으니 된다고 해야하나?)
