Error Enabling Extension: Python Module Not Found

Omniverse Isaac Sim
1

Hello,

I am trying to create a custom extension in Isaac Sim. I used the “Generate Extension Template” tool and executed the “Loaded Scenario Template”. However, when I try to enable the extension, I encounter the following error:

[Error] [omni.ext._impl.custom_importer] Failed to import python module my_extention_python. Error: No module named 'my_extention_python'. Traceback:
Traceback (most recent call last):
  File "/home/user/.local/share/ov/pkg/isaac-sim-4.2.0/kit/kernel/py/omni/ext/_impl/custom_importer.py", line 76, in import_module
    return importlib.import_module(name)
  File "/home/user/.local/share/ov/pkg/isaac-sim-4.2.0/kit/python/lib/python3.10/importlib/__init__.py", line 126, in import_module

  File "<frozen importlib._bootstrap>", line 1050, in _gcd_import

  File "<frozen importlib._bootstrap>", line 1004, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'my_extention_python'

Here are the steps I have taken so far:

  1. Used the “Generate Extension Template” tool to create the “Loaded Scenario Template”.
  2. Tried to enable the extension, but encountered the above error.

Could anyone provide guidance on how to resolve this issue?

Thank you in advance for your help.
