Isaac Sim 4.0: ModuleNotFoundError: No module named 'omni.isaac'

Omniverse Isaac Sim
1

I install isaaclab using Isaac Sim Binaries.
When I follow this link to verify the isaac lab installation, after I run

python source/standalone/tutorials/00_sim/create_empty.py

I get the following issue:

Traceback (most recent call last):
  File "/home/brain/Workspace/omniverse/isaaclab/IsaacLab/source/standalone/tutorials/00_sim/create_empty.py", line 20, in <module>

ModuleNotFoundError: No module named 'omni.isaac'

Hi @Tips0

Use ./isaaclab.sh -p source/standalone/tutorials/00_sim/create_empty.py to run the script when installing using the Isaac Sim binaries

我也遇到同样问题，如果解决能告诉一下？

I also tried to install “Installation using Isaac Sim pip (experimental)”.
When I run

pip install isaacsim-rl isaacsim-replicator isaacsim-extscache-physics isaacsim-extscache-kit-sdk isaacsim-extscache-kit isaacsim-app --extra-index-url https://pypi.nvidia.com

I got the following errors:

Hi @Tips0

Installing Isaac Sim with pip requires GLIBC 2.34+ version compatibility.
To check the GLIBC version on your system, use command ldd --version .

Got the same issue, no solution? if I installed verything from pip, I am OK, but I want to check those source code so I installed isaac-sim from the omniverse, and got such issue.
