PyRep Qt libcoppeliasim.so.1 errors

[jooker23]

I downloaded Pyrep as follows om my ubuntu 18.04. https://travis-ci.com/github/stepjam/PyRep.

When i used ‘’ python3 -m unittest discover tests’’ and gym-vrep example, i got two different errors 1-

Got keys from plugin meta data ("xcb") QFactoryLoader::QFactoryLoader() checking directory path "/home/tan/python-environments/env/bin/platforms" ... loaded library "/home/tan/stepjam/PyRep/CoppeliaSim_Edu_V4_1_0_Ubuntu18_04/platforms/libqxcb.so" qt.qpa.xcb: could not connect to display :99.0 qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/tan/stepjam/PyRep/CoppeliaSim_Edu_V4_1_0_Ubuntu18_04" 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, webgl, xcb.

How can i fix it. Please help me about this situation. Thanks,

I have the same issue like yours. And I deal with it by creating a new conda env for PyRep and make sure your CoppeliaSim_Edu version is 4.1, python = 3.7.7.

@houyanxu @jooker23 Have you solved the problem 1? I have the same error. I run the examples on my GPU server but there is no monitor. Is there an option I can choose to close the display?
