Cannot import omni.isaac.core

Omniverse Isaac Sim

I can sucessfully import omni.isaac.gym with no errors. But I’m getting the following error when I tried to import omni.isaac.core.

The only thing in python script (helloword.py) is:
import omni.isaac.core.omni.isaac as core

The way I run the code is (PYTHON_PAHT =[omni_pkg]/python.sh):
$PYTHON_PATH helloword.py

I got the following error:

Traceback (most recent call last):

There was an error running python

Do anyone know how to solve it?
