mujoco.FatalError: OpenGL version 1.5 or higher required

[PROPHETE-pro]

Dear sir,

Thank you all for contributing to the community for this repo. I ran into some problems that made me unable to run the repo, so I am asking for your kind help.

After installing the repo following all the instructions provided in the ReadME, I tried to run the command:

python examples/simple_mushroom_env/example_unitree_a1.py

However, the code ended with "mujoco.FatalError: OpenGL version 1.5 or higher required".

I have searched about the OpenGL online and tried to install it using 'sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev', but it did not help.

Do you mind if you can provide some advice about how to solve this problem? Thank you so much for helping!

Hi,
what os are you running? Could you try to download the latest mujoco-binaries and check if you can run the simulate file found in mujoco-x.x.x/bin?

I am running on Ubuntu 22.04.2 LTS. I downloaded mujuco-3.1.6 and the 'simulate' file is working, but when running loco-mujoco, the error is still there.

So the simulate file can open a window and properly render everything? Maybe the issue is with glfw. Could you check the version? You could try to upgrade by pip install --upgrade glfw. It's hard to help here since I can not reproduce the error. I just found a related issue on openai/mujoco-py#378. You probably have seen them already though.
