My GPIO is not working

Hi, I try to follow the guide that using python to generate 3.3v output from Jatson nano GPIO pin, but I found out that the GPIO is not functioning. I used python,
code is below:

import Jetson.GPIO as GPIO

There are not voltage output from pin 12 (BCM).
What should I do ?

Please check the 40-pin expansion header docs in DLC:

so, why isn’t it easier? So crazy, right. And I need to do this from a docker, since that is where I run ROS2. I would do it on bare metal, but NVIDIA refuses to update to Ubuntu 20.04 (so out of date IMHO)
