[Question] isaacsim omni.isaac.sim.python.kit giving error

[meghbhalerao]

I am trying to install isaac-sim following the docs here - https://isaac-sim.github.io/IsaacLab/main/source/setup/installation/pip_installation.html

When I run isaacsim things work fine and I get an empty window (which I think is expected according to the docs). This window looks like this -

Everything works fine up until I run - isaacsim omni.isaac.sim.python.kit which gives me the following error -

My machine specfications are the following -

Operating System: Ubuntu 24.04.1 LTS              
 Kernel: Linux 6.8.0-45-generic
 Architecture: x86-64

I am ssh-ed into this machine using ssh -XY user@host and xclock, xeyes, xcalc work fine.

My local machine is an M2 MacBook Air.

Additional info (may be relevant so including this) -

1. I also installed the kit-app-template which is a part of the omniverse from here https://github.com/NVIDIA-Omniverse/kit-app-template (I had done this sort of accidently earlier as I didn't know about the isaac lab and related things)
2. I have the omniverse launcher, and that seems to be working fine (that is if I launch the .AppImage file on my host machine which is the linux box, it renders on my local macbook)

Thanks for the help!

Hi @meghbhalerao

In order to run isaacsim omni.isaac.sim.python.kit there is necessary to install all the Isaac Sim - Python packages and not only the few ones Isaac Lab docs indicate (minimal ones to run Isaac Lab).

In any case, your setup if fine. Just skip that step

Thanks for the help! Could this be made clearer in the docs (a possible feature request) here - https://isaac-sim.github.io/IsaacLab/main/source/setup/installation/pip_installation.html#verifying-the-isaac-sim-installation - since the title says Verifying Isaac installation, and it could be confusing for the user as they might think that that is an issue with the install.
Please let me know if I am missing something, thanks!
