[carb.scenerenderer-rtx.plugin] Failed to execute RenderGraph on device 0.

[explore-code-world7]

bug log file: kit_20250602_152439.log

Describe the bug

• When I running env with camera sensors with excessive num_envs,

./isaaclab.sh -p scripts/reinforcement_learning/rsl_rl/train.py  --task Isaac-H1-Walk-v0  --info  --headless  --enable_cameras  --num_envs 128

• a bug reports as follows:

• it may be caused by excessive gpu consuming, but the output of nvidia-smi shows gpu consuming is far less than gpu storage.

• besides, when decreasing num_envs to 64

./isaaclab.sh -p scripts/reinforcement_learning/rsl_rl/train.py  --task Isaac-H1-Walk-v0  --info  --headless  --enable_cameras  --num_envs 64

• the code run normally
  

• with gpu consuming less than 8G

• even double env nums, the gpu consuming should < 16G, and the former output also shows 8G which << single gpu storage=24G

• it's really confusing, expecting your answer

a link which may be helpful

Steps to reproduce

• left out

System Info

• Isaac Sim Version: 4.5
• OS: [Ubuntu 22.04]
• GPU: RTX 4060
• CUDA: 12.4
• GPU Driver: 550.144.03

Checklist

• I have checked that there is no similar issue in the repo (required)
• I have checked that the issue is not in running Isaac Sim itself and is related to the repo

Thank you for posting this. Your log reports an earlier error on GLInteropContext that may be triggering this. Are you running this locally or on the cloud? If the latter, be sure you have export DISPLAY=:0, which has resolved this issue in some cases. Also, please try using the recommended driver.

• Thank your timely reaply~
• I'm on a server.
• the former javascript runs well with GLInteropContext Error, so the problem may not be it.

./isaaclab.sh -p scripts/reinforcement_learning/rsl_rl/train.py  --task Isaac-H1-Walk-v0  --info  --headless  --enable_cameras  --num_envs 64

• log of correct running on 64 envs: kit_20250603_181236.log

• I tried export DISPLAY=:0(before) , and problems remains the same .

• further, I updated nvidia driver version and export DISPLAY , the problem remains~~

• looking forward to your reply~

Following up, the driver you are using is still not the recommended one. You may also want to try tiled rendering. I'll move this post to our Discussions section for follow up.
