Hello guys,
I am returner to jestson nano from times of Corona. I can not make it worlk now to use cv2 and adafruitcircuit-servokit libraries together on same version of python. cv2 is working up to 3.6.9 and i can not install adafruit on 3.6, but only to python 3.8.
I know that before somehow i made it to work together and I really need help.
i had to install adafruitcircuitpython 1.3.8, that is latest version i can get to install without mistakes and in fact python3.6.9 recognises it in my code oss . Now i get constantly permission error.
I did
sudo usermod -aG 12c username
sudo groupadd -f - r gpio
sudo usermod -a -G gpio username
i have checked i2cdetect and it sees the board
is there any way around this or anyboady knows how to run both openCV and adafruitcircuit servokit
on python 3.6?
thanks
i solved permisssions with this
$ sudo usermod -aG gpio eurobus
$ sudo chown root.gpio /dev/gpiochip0
$ sudo chmod 660 /dev/gpiochip0
and BTW this needs to input at every reboot.
now i get this in code-oss and I am totaly confused.

help please
Hi,
On Jetson Nano with Jetpack 4, you would need to use old version of some software stacks. Please try the solution like:
Hi DaneLLL,
dontr You have something more simple, this is too complicated for me…
I have my openCV working fine, what I need is how to get over those last errors when I already have adafruit servokit going.
