Fail to Generate Data

[wheltz]

Hi, I'm running the following command to generate robot data:
python generate_robot_data.py --model_xml_dir mujoco_menagerie/universal_robots_ur5e
After running for an hour, the progress and rate remain at 0. I'm on a headless server, so I wanted to check if there are any additional dependencies or requirements I might be missing (e.g., specific libraries or hardware like a display).
Any suggestions would be appreciated.

Thanks!

A couple pieces of advice for debugging this issue:

1. make sure that you can launch and render images in mujoco using a minimal script. there are components like lock files and Ray multiprocessing in the generate_robot_data.py script which might be hiding the issue
2. you may try inserting some breakpoints or print statements around the file, run it with a single process and see where it gets stuck.
