When I ran the examples

I downloaded isaacgym, and I ran the code “joint_monkey.py” on the Ubuntu Terminal.
But in my enviroment, I got an error message:

root@d967d924ca56:/opt/isaacgym/python/examples# python joint_monkey.py

I built my environment with docker in docker folder with bash build.sh and bash run.sh.


  • OS: Ubuntu 20.04

  • GPU: RTX 3070

Any idea to solve this?
Thank you.

Hi @ksterx ,

With the default docker build and run scripts shipped in Isaac Gym, we do not support running in docker with the viewer. You can try adding the --headless flag on examples that support headless mode to run without the viewer. Alternatively, you can give this docker run script a try (it’s not well tested yet) to see if you can get the viewer running in docker. run.sh (201 Bytes)


i also have this problem, i only use conda environment.

    Thank you.
