Hi! I cannot complete the environment configuration, I meet a problem called:
loading from the config file spirl/configs/skill_prior_learning/kitchen/hierarchical_cl/conf.py
Warning: Mujoco-based envs failed to import. Set the environment variable D4RL_SUPPRESS_IMPORT_ERROR=1 to suppress this message.
No module named 'mjrl'
Warning: Flow failed to import. Set the environment variable D4RL_SUPPRESS_IMPORT_ERROR=1 to suppress this message.

warnings.warn(message, GLFWError)
Segmentation fault (core dumped)

I don't change anything except the wandb part.
I have found many ways but cannot solve them. Do you have any solutions?

Thank you very much!

Hi!
Sorry for the late reply, I missed this issue and just came across it!

I suspect that the error you are encountering is not specific to the SPiRL codebase. My guess is that you are running on a headless server, ie without a connected display? I think mujoco is trying to render on your display, but can't find a display.

One thing you can try is to open a virtual display by running Xvfb :1 -screen 0 1024x768x16 & before starting the script. This will create a virtual screen that Mujoco can use for rendering.

Hope this helps!
