[Question] How to get the result of the example?

[wayne-weiwei]

Required prerequisites

• I have read the documentation https://omnisafe.readthedocs.io.
• I have searched the Issue Tracker and Discussions that this hasn't already been reported. (+1 or comment there if it has.)
• Consider asking first in a Discussion.

Questions

After I trained the ppo-lag model using the python train_policy.py --algo PPOLag --env-id SafetyPointGoal1-v0 --parallel 1 --total-steps 10000000 --device cpu --vector-env-nums 1 --torch-threads 1, I can not gain the result when using omnisafe eval runs/PPOLag-\{SafetyPointGoal1-v0\} and meet the following problem.

[Gaiejj]

A similar issue is in #329. We are reproducing this issue and fix this problem. Can you provide more information about your running environment? e.g.

Are you running on a headless server?
Are you running in Linux?
Are you using docker?
Are you building from source or pypi?

We sincerely hope to resolve your issue. We hope you can provide more detailed information so that we can better pinpoint the problem.

[wayne-weiwei]

Thank you so much for your reply and help.
I installed OmniSafe from source, and ran it in the Linux system on the dedicated server following the guidance in the guithub.

[Gaiejj]

I attempted to replicate your issue on a Linux headless server but was unsuccessful. After executing export MUJOCO_GL=osmesa, I successfully obtained the following results. I have also carefully compared the differences between our environments and suspect the issue may lie with the version of ffmpeg. By running ffmpeg -version, I discovered that my version is 4.2.7. I will display my complete Python environment information and provide a related issue for reference.

My running log:

[wayne-weiwei]

I sincerely appreciate your patience and assistance. Thank you very much. I downgraded the imageio-ffmpeg package to address compatibility issues

and ffmpeg package

However, the error still persists

It is a problem with the OpenGL library.

[Gaiejj]

This issue is quite unfamiliar to me, but I found a related issue that might help you. mcfletch/pyopengl#90

[wayne-weiwei]

Thanks to your help, I have successfully implemented the solution. Your support has been invaluable. Thank you!
