Error with Qt platform plugin "xcb" when start labelImg #630

Closed vovaekb closed 4 years ago

vovaekb commented 4 years ago

I am using Ubuntu 14.04. I have installed labelImg both ways: from source and using pip install. In both cases when start labelImg I get following error: 

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

@vovaekb Have you try the following yet? Run this first: sudo apt-get update Then run command: sudo apt-get install pyqt5-dev-tools

vovaekb commented 4 years ago

@AnhPC03 Yes, I tried it. I did all steps from guide and this didn't work.

@vovaekb can you show all errors?

In my case the issue was that libxcb-xinerama0 was missing. I've found out after setting the export QT_DEBUG_PLUGINS=1

I have the same issue, and use 'sudo python3 labelImg.py', it works for me. My os is ubuntu18.04. @vovaekb
