My system: 13600k, 64gig ram, 3060 12 gigs, Ubuntu driver 525.147
First I installed Isaac sim conda environment issac-sim using the given document which is working perfectly Python Environment Installation — Omniverse IsaacSim latest documentation
Then I followed the instructions here step by step from here:
Installation Guide — orbit documentation
but I have encountered an error regarding no omni isaac found so I source ~/.local/share/ov/pkg/isaac_sim-2023.1.1/setup_conda_env.sh in my orbit conda environment as well.
When I run the script using ./orbit.sh -p source/standalone/demos/quadrupeds.py for instance isaac would be opened and freeze on this line of code:

Hi @ahn.paf - Can you confirm that you are following this documentation for installing Orbit?
https://isaac-orbit.github.io/orbit/source/setup/installation.html
I managed to solve the problem and run the first example by logging in to nucleus, but that was the only time it worked. After that, my Isaac sim 2023 broke down completely. I think it has something to do with the python path, because I couldn’t run Isaac sim or OIGE properly, and I reported it in another post.
Another problem that I still have is that my Isaac sim freezes at this line, no matter which example I try to run. That’s very odd.
Because of these issues, I uninstalled Isaac 2023 and reinstalled it, and now everything works fine without orbit.
Do you think I should try orbit again? Do I need to source the Isaac folder every time I run Isaac using conda? I don’t think this is related, but I also suspect that orbit has a big performance problem, at least for me.
I have forward your question to devs. They will review the issue and provide further instructions.
Hi,
To me, this issue seems to be because of Nucleus connection. If that is not happening properly, then Isaac Sim does a “search” over all possible paths and tries to connect to multiple different servers until it finds one that it can connect to. Please make sure you check the Isaac Sim instructions on connecting Nucleus.
