Hi @vignesh14! When you enabled it manually from the extension manager UI, did you check autoload as well?

When you use enable_extension to enable it, do you still get the same error (assuming you have already enabled and autoloaded it in the GUI)?

Have you tried ./isaac-sim.sh --ext-folder {path_to_user_ext_folder} --enable {ext_directory_name}?

No , i get this issue when i to launch Issac sim using /python.sh , when i open ./isaac-sim.sh as it is it is already loaded and works without any issues

@vignesh14 Let me reach out to the internal team about this issue.

you have to add the path to setup_python_env.sh

So the runtime locates the extension, I wanna add functionality to the isaacsim project but there is no information on how they organized the repoman which is used to put together these scripts.

Hi @vignesh14! Do you want to use the import before SimulationApp or after?

If you want to use it before SimulationApp starts, then it has to be in setup_python_env
If you can use it after, then enabling the extension after SimulationApp starts in their script will be enough
