Btw, I had to comment out the gym import cuase there was a problem with that too.

Hello,

Thank you for bringing this issue to my attention. Based on the traceback, it appears that the error is related to the Mujoco installation and its interaction with OpenGL.
Could you try the following installation?

pip install PyOpenGL

Or I recommend checking your Mujoco and relavant packages installation. Make sure you have the required dependencies and the correct version installed. You can refer the documentation of the Mujoco and relavant packages installation for more details: Mujoco Installation

Feel free to reach out if you need further assistance or if the problem persists.
