Continuing the discussion from Issac Sim GUI Freezes
Hey @pranav7296, for the Windows system, is it the first time to load JetBot in Isaac Sim within 10 seconds?
Hi,
Ya, It was the first attempt. I am still not able to load Jetbot via python script on Ubuntu 22.04 LTS. The screen is frozen even after waiting for 30 min.
Does the terminal give any messages like warnings or errors?
Hi,
I have specified the warning message in the original post.
Oh thanks… I checked mine, besides that your loading time is much slower than mine and missing one last warning, everything else is the same as mine.
Here is the last warning from my terminal.
2024-09-10 23:10:23 [15,120ms] [Warning] [omni.physx.plugin] Detected an articulation at /World/Fancy_Robot with more than 4 velocity iterations being added to a TGS scene.The related behavior changed recently, please consult the changelog. This warning will only print once.
Could you also run top in your terminal and show me the printout?
Let me reach out to our internal team and see what else could affect loading.
Hi,
I can see there are few other warnings in the terminal:

It might be related to local nucleus server being stuck.
Could you please try killing all omni services running on the machine and then start the launcher again?
It worked!! Did the following steps to resolve the issue:
- Reinstalled the Nucleus Service
- Killed All Omni Services and restarted the launcher.
After this, I was able to load JetBot in a few seconds via a python script.
Thanks for your(@zhengwang ) suggestions.
