Detailed Description

Hello I’m using isaac sim 4.0.0 by pip install in docker container. In container, i got this error.
File “/opt/conda/lib/python3.10/site-packages/isaacsim/exts/omni.isaac.kit/omni/isaac/kit/utils.py”, line 17, in
from omni.kit.usd import layers
ModuleNotFoundError: No module named ‘omni.kit.usd’

So i change the version to 4.5.0, but i got the same error.
in isaac sim installed by pip, doesn’t module ‘omni.kit.usd’ exist?

and i write the Dockerfile like this

‘’’
FROM pytorch/pytorch:2.2.0-cuda12.1-cudnn8-devel

RUN pip install isaacsim[all]==4.0.0.0 --extra-index-url https://pypi.nvidia.com

RUN pip install isaacsim[all]==4.5.0 --extra-index-url https://pypi.nvidia.com

Hi @kes2387

You need to install also the extscache packages (see: Installation using PIP, point 3).

Also, please, don’t install both versions in the same Python environment.
