No module named 'omni'

[ethan-allan]

Hi there,

Trying to set up IsaacLab on Ubuntu 22.04, following the guide provided here: https://isaac-sim.github.io/IsaacLab/main/source/setup/installation/index.html

I'm strictly following the guide however whenever I reach the IsaacLab installation step the terminal hangs on importing protobuf, giving a message that the install is taking longer than usual.

Following this I cannot verify the installation using any of the examples, recieving the error : No module named 'omni'

This is the terminal output:

INFO: This is taking longer than usual. You might need to provide the dependency resolver with stricter constraints to reduce runtime. See https://pip.pypa.io/warnings/backtracking for guidance. If you want to abort this run, press Ctrl + C.
