Issue while running rlbench_gym.py

[Sid-B-K]

I am getting this issue when running examples in RLBench/examples/rlbench_gym.py

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid Aborted (core dumped)

I am not getting this error while running other examples in RLBench.

Any help would be appreciated! Thanks.
