issue when running python slicer-gui.py

[Parisa-Bagherzadeh]

i got this after running python slicer-gui.py :
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" 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: minimalegl, offscreen, xcb, wayland, eglfs, wayland-egl, minimal, vnc, linuxfb, vkkhrdisplay.

Aborted (core dumped)

How to fix this?

Since it works on my computer, I can't reproduce this issue. You may have to find solutions yourself.

Try this command:

sudo apt-get install libxcb-xinerama0

or

sudo apt-get install -qq libglu1-mesa-dev libx11-xcb-dev '^libxcb*'
