This error occurs when I run eval.py

I wanted to run eval.py, but this error occurred.

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, webgl, xcb.

It should be because I can't use the graphical interface on the server, is there any option to evaluate it without qt.

Hi,

Thanks for reporting this issue. Yes, from my experinece, it could be because you are trying to evaluate on a headless server on RLBench. Unfortunately, I don't have a very concrete fix for this issue. But, a couple of things that might be helpful (in order)

-- Try to use the --headless flg with eval.py.

-- Try this fix.

-- Try using xvfb-run as discussed here.

-- Try using VirtualGL as discussed here.

Please, let me know what solution works for you.

@chenjiayi-zxx Were you able to solve this issue? It would be nice to if you can share what solution worked for you.

I had the same error while I tried to run eval.py on server. Usage of xvfb-run with --headless flag helped for me.

Closing because of inactivity. Please feel free to reopen if the issue persists.

After downloading VirtualGL, using xvfb-run works for me

It works! Thanks for your sharing!

I tried all of these methods, but i still got this problem

[LogSSim]

Oh, I solved this problem. I changed other CoppeliaSim version. It works now.

I inevatiblly bumped into this issue ,and can't solve it through your previous advices,my cloud server has no x config ,is that problem?
Hope you give me some advices.
