Verify Isaac Lab installation issues :

I encountered some problems when installing Isaac Lab. When I performed the verification, an error report came out, which made my Isaac sim unable to be opened. If you have the answer, please help me. Thank you.

I use conda virtual environment and python 3.10.14 additionally I installed:

pip install isaacsim==4.1.0.0 --extra-index-url https://pypi.nvidia.com

pip install isaacsim-extscache-physics==4.1.0.0 isaacsim-extscache-kit==4.1.0.0 isaacsim-extscache-kit-sdk==4.1.0.0 --extra-index-url https://pypi.nvidia.com

When I execute: python source\standalone\tutorials\00_sim\create_empty.py , I get the following error...

I first installed Isaac Sim in Omniverse and then installed Isaac Lab using the binary archive. When I perform installation verification, I get the first error and then install: pip install isaacsim==4.1.0.0 --extra-index-url https://pypi.nvidia.com and pip install isaacsim-extscache-physicals== 4.1.0.0 isaacsim-extscache-kit==4.1.0.0 isaacsim-extscache-kit-sdk==4.1.0.0 --extra-index-url https://pypi.nvidia.com, the 'cp950' problem occurs when the verification program is executed again.

first error:

My display card driver version is 555.99, the display card is RTX3090, and I use the virtual environment conda.

Everything installed in the conda environment.
