What do you mean run it on IDLE?

Did you confirm the sensor driver loaded?

[oliekim55]

When I load a Python file in IDLE and press F5, the code runs, but when I try to execute it in the terminal window with python3 xx.py, the following error occurs.

Please confirm the camera driver by below commands.

v4l2-ctl --list-formats
nvargus_nvraw --lps

[oliekim55]

These are the results of commands executed in the terminal

Looks like argus recognize the camera.
Maybe check below code.

This is the result of running the above code.
