Using Adafruit_CircuitPython_ServoKit in a container

[mmatesic01]

Hello,
I have no issues installing and enabling and using Adafruit_CircuitPython_ServoKit locally (outside container) on Jetson Nano.
I run this simple code (and servos move):

from adafruit_servokit import ServoKit

_kit = ServoKit(channels=16)
pan = 90
tilt = 90

kit.servo[0].angle = pan
kit.servo[1].angle = tilt_

But when installing it inside container and running the same code, I get the next message:

_Traceback (most recent call last):

IncrementalDecoder.init(self, errors)
RecursionError: maximum recursion depth exceeded

What else am I missing in my container?

"i2cdetect -y -r 1" shows me that PCF9685 controler is visible inside container.

This looks to be an issue with Blinka rather than the library, as it's struggling to import the board module. If you update to the latest version of Blinka, do you still see it? You may want to file this issue there if so: https://github.com/adafruit/Adafruit_Blinka
