GPIO error while trying to use PWM for LED dimming

Hello, I am a newbee here, trying to replicate the video experiment from Mr Paul McWhorter: AI on the Jetson Nano LESSON 59: PWM on the GPIO Pins of the Jetson Nano - YouTube

I had to run the troubleshooting instruction to set the Pin 33 to pwm2 as provided on:

The commands that I am using for getting started are:

import RPi.GPIO as gpio
my_pwm = gpio.PWM(33,500)

But nothing happens. And so, when I exit out of the Python environment, below error log gets generated:
Exception ignored in: <bound method PWM.del of <Jetson.GPIO.gpio.PWM object at 0x7fa031e4e0>>
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/Jetson/GPIO/”, line 606, in del

File “/usr/lib/python3/dist-packages/Jetson/GPIO/”, line 259, in _disable_pwm
NameError: name ‘open’ is not defined

Details about my board:
R32 (release), REVISION: 3.1, GCID: 18186506, BOARD: t210ref, EABI: aarch64, DATE: Tue Dec 10 06:58:34 UTC 2019

hello gunjan_narulkar,

please examine your PWM status as below,
i.e. $ sudo cat /sys/kernel/debug/pwm

please also refer to below forum discussion threads for reference,
