This may be due to the version of Isaac Sim you are using. Please try version Isaac Sim 4.2.

Thanks for your response, however, I have used the latest Issacsim 4.2.

Did Isaaclab’ developers test to use A100 to render?

I would also look at updating the driver version if possible, I find more stable results with 550. I also run into trouble with A100 rendering due to lack of RTX cores.

Thank you for your suggestion. However, my driver version is already 550.127.05, and Vulkan is also installed. It seems that the lack of RTX cores might be the core cause of the issue? Interestingly, this problem doesn't occur in Isaac Gym, for instance, when running Isaac Gym with the A100.

Please use headless mode to gain more training speed (much better). For visualizing purpose, please use play.py script and set a low number of environment (e.g: 120).
