Windows fatal exception: int divide by zero

Omniverse Isaac Sim

Hello,
I am trying to run the standalone example of “object_based_sdg_utils.py”. But when I run it with headless set to False it gives me the below error. When I set headless to True, the script runs and works as expected.
Specifically, the error happens when I try to create the simulation app in this line:
simulation_app = SimulationApp(launch_config=launch_config)
Actually, it happens in all standalone examples wherever I try to create a simulation app with “headless” set to False.

Any idea what is causing this?

I’ve noticed that ‘headless’ is set to False by default. I couldn’t reproduce this issue on my Ubuntu setup. Is this specific to Windows? It seems no users have reported this before.

3

It seems that this error might be specific to Windows, as I’m encountering a Windows fatal exception: int divide by zero. Unfortunately, I don’t have access to a Linux environment to verify if the issue persists there. I noticed a similar issue reported on the Isaac Lab GitHub page, with details available in Issue #921.

Also, I should add that I uninstalled/installed everything multiple times and the issue persists.

Hi there, I could not reproduce on my windows machine. It seems you have newer driver, maybe that is the issue.

Thank you for replying,
I have the latest NVIDIA Recommended Driver installed on my Windows machine, 566.03, that the NVIDIA app is recommending. I’ll install an older driver and get back to you.

8

So, I installed the NVIDIA RTX Driver Release 550 R550 U10 (553.24) | Windows 11 which is the driver from the production branch from the NVIDIA Manual Driver Search and the issue still persists. I have a Quadro RTX 5000 series GPU for reference.

@paschalis.choropanitis have you figured out this problem?

10

No, the problem still persists. I’ve tried many different drivers at this point. Maybe it is a Quadro specific bug, because in my other Windows machine with an RTX 2060, everything works fine.

Hello,

Also reporting the same issue on my side. Using an RTX3080 with Game Ready Drivers 566.36

Hello everyone,

I had the same problem and found a solution for my setup. I got the same errors trying to run Isaac Lab environments. I recently got a new 3090 (NVIDIA-SMI 566.36, CUDA Version: 12.7, Windows) and wanted to overclock it with MSI Afterburner which caused the errors. Even with the default settings (no overclocking) it still happens so once closing everything runs normal. I can also replicate the error by simply opening MSI Afterburner.

I know this fix is not really technical but perhaps it has something to do with overclocking?

Kind Regards,
Lychee

Hey,

I confirm that after turning MSI Afterburner off, the errors are gone. I did not do any overclocking whatsoever though, I just installed MSI Afterburner without changing anything.

Thanks!
