Question

Hi, I've been trying to install IsaacLab on my workstation running Ubuntu 20.04. I followed all the steps using the binaries installation method. I successfully verified the installation on another PC with an RTX 3080 GPU, so I believe the method should be correct.

However, while some demos (such as the showroom demos featuring quadrupeds) run successfully, others, including demos with RL wrappers (like training with rsl_rl on the Isaac-Reach-Franka-v0 task), fail. Specifically, for some showroom demos, the Isaac Sim window crashes. For rsl_rl demos, it reports errors:

[INFO]: Base environment:

For reference, I am using the recommended driver vision 535.192.03 with CUDA 11.8, on a 4090 + 13900k workstation with 32G RAM. I have re-installed the ubuntu system and I have tested Isaac Sim and be sure it works well so I assume the problem is from IsaacLab. If someone had the similar questions and fixed it, please let me know. Thank you for your help.
