Attempt to retrieve context when no valid context

I used WSL + Ubuntu 24.04.

I have the same problem like u, BUT USING WSL Ubuntu 20.04 https://github.com/Genesis-Embodied-AI/Genesis/issues/43#issuecomment-2554496334

By the way, may I inquirer how can u update the OpenGL version in order to solve the previous pyglet.gl.ContextException: Could not create GL context problem in my issue

[vhartman]

Some possible solutions are in #37

I have the same problem like u, BUT USING WSL Ubuntu 20.04我有和你一样的问题，但是使用 WSL Ubuntu 20.04。 #43 (comment)

By the way, may I inquirer how can u update the OpenGL version in order to solve the previous pyglet.gl.ContextException: Could not create GL context problem in my issue顺便问一下，我可以询问如何更新 OpenGL 版本以解决我问题中的 pyglet.gl.ContextException: Could not create GL context 问题吗？

for me (Ubuntu 20.04), the solution in #37 worked well:

import os
os.environ['PYOPENGL_PLATFORM'] = 'glx'

import genesis

It is noted that the MuJoCo GL should be set by export MUJOCO_GL=glx to avoid the MuJoCo error like ImportError: Cannot use EGL rendering platform. The PYOPENGL_PLATFORM environment variable is set to {!r} (should be either unset or 'egl').
