Adafruit_MotorHAT_Motors.py shows nothing

Hi so I’m trying to connect my motor driver to my jetson nano. I am using the 16-Channel 12-bit PWM/Servo Driver I2C PCA9685

I’ve connected the pins but I don’t know how to change the base address of adafruit motor hat from 0x60 to 0x40 (I’ve been told that to work with PCA685 I need to change the base address)

I found that I can change it by opening -
sudo nano /usr/local/lib/python3.6/dist-packages/Adafruit_MotorHAT-1.4.0-py3.6.egg/Adafruit_MotorHAT/Adafruit_MotorHAT_Motors.py

but it shows an empty file on running that command.

Please check below topics to see if can help:
