Qt platform issue in benchmark

[ammohamedds]

When I run notebook_benchmark in jupyter it works fine, plots of benchmark appear, while executing it on pycharm, the below error appears due to a Qt platform issue even though I've reinstalled it several times and the agents are trained and all codes are implemented successfully except only ploting part.

QObject::moveToThread: Current thread (0x20247e0) is not the object's thread (0x5c0a590).

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/ahmed/PhD/CyberBattleSim/CyberBattleSim/cybervenv/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.

Available platform plugins are: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.

Has anyone encountered such a problem?

The issue is related to qt in Linux, so if you use pycharm,, delete/remove plugins from cv2 folder
/venv/lib/python3.7/site-packages/cv2/qt/plugins
