[Bug Report] --device_id can not work

[kevincheng3]

I think the problem may be related to running Isaac Sim， my classmates and I have the same problem that prevents us from using the second graphics card

Describe the bug

When I use command --device 1 to run the simulation using cuda:1, the simulation cannot run. The isaacsim window will pop up but the screen is black and the simulation is stuck. However, it can run normally when command --device 0 is used.

Steps to reproduce

For example, running exist scripts with ./isaaclab.sh -p source/standalone/demos/hands.py We can successfully run the script through ./isaaclab.sh -p source/standalone/demos/hands.py --device_id 0

But the simulation cannot be run with ./isaaclab.sh -p source/standalone/demos/hands.py --device_id 1

And the isaacsim window is in black screen state

System Info

• Isaac Sim Version: 4.1.0
• OS: [Ubuntu 22.04
• GPU: RTX 4090 *2
• CUDA: 11.8
• GPU Driver: 535.183.01

I don't know if this might help but a possibility is to define CUDA_VISIBLE_DEVICES as discussed in https://discuss.pytorch.org/t/how-to-change-the-default-device-of-gpu-device-ids-0/1041

Hi,

Have you tried headless?
