`ModuleNotFoundError: No module named 'omni.isaac.core'` Why this error appear?

Omniverse Isaac Sim

Hi,

Now I trying to run OGIE with skrl with my custom task environment.

Error message ModuleNotFoundError: No module named 'omni.isaac.core' appeared from my task environment code.

It does not have an error when I run the example file and the example file has the same import procedures.

import omni
from omni.isaac.core.prims import RigidPrimView

The error message comes from above at the almost first line.

Below is the entire error message.

I check with

import sys
print(sys.path)

and I found Isaac Sim does not contain modules from exts.
Sometimes I feel this is kind of a prevalent problem.

I can solve that I made an env = get_env_instance(headless=True) instance before import environment class and SimConfig.
