I get an error when I run a physics simulation on Isaac smi

Autonomous Machines Isaac Omniverse Isaac Sim
#1

Hello,I looked at the physics section of the omniverse docs and tried to drop the cube, but when I press play, I get the following error and the isaac smi doesn’t work.
Does anyone know the cause of the problem?
Any help or suggestions would be appreciated.
Thank you.

Hi mri_y

Can you paste your NVIDIA-smi here, so I can see your GPU and driver.

Kindly,
Liila

Thank you for replying.
Nvidia-smi looks like this:

#4

Please get the nvidia-smi in another terminal while running the sim. I want to see if the Isaac Sim is using GPU, because it seems it doesn’t. you should see the name Omniverse-kit in the list of the Processes.

THanks,
Liila

I’m sorry, I misunderstood.
The nvidia-smi running isaac smi looks like this:
Currently I’m only running the isaac-smi json file, not the one named omniverse-kit
Could you tell me how to run omiverse-kit?

Thank you

#6

So in one terminal you run isaac_sim.sh to run the Isaac sim
and then in another terminal you run nvidia-smi

#7

I understood that.
After executing isaac_smi.sh, the image when nvidia-smi is executed is as follows.

GPU seems to be using.
Thank you

#8

After reinstalling isaac_smi and changing the NVIDIA driver to 450.59,
I was able to drop cubes.
Thank you very much.

Hi mri_y

I am glad your issue has been resolved
