Hello,
I have gotten the robot https://www.waveshare.com/product/ai/robots/mobile-robots/jetracer-ai-kit.htm 4GB version with eMMC drive with preinstalled Ubuntu 18.04 LTS, jetpack 4.6.1. It was missing a lot of crucial modules to even run the jupyter notebook. I have followed the waveshare tutorial: https://www.waveshare.com/wiki/JetRacer_AI_Kit
Nothing really worked for me. Besides this thread: https://www.sahilramani.com/2020/10/how-to-setup-python3-and-jupyter-notebook-on-jetson-nano/.

I stumbbled uppon a wall trying to install servokit module. Python version on my jetson nano is 3.6 which isnā€™t supported by adafruit servokit. I also tried installing python 3.8 (changing base python version in system corupted ubuntu I was unable to turn on console so i reverted changes) and then run command:

~$ python3.8 -m pip install adafruit-circuitpython-servokit

it resoults with error: Failed building wheel for sysv-ipc. I wanted to flash the eMMC drive with newest jetpack and newer python and ubuntu, but sd card can not be detected for some reason. The aim is to controll servos via jupyter notebook. It is my dissertation project and I am totally lost. Please help.

Suggest to check GitHub - NVIDIA-AI-IOT/jetracer: An autonomous AI racecar using NVIDIA Jetson Nano to see ifcan find more information, or file a bug there.

Did you solve this? Iā€™ve been having a similar issue for a while.

Not yet, i will share here if i will manage to overcome these issues. It would be cool if we could share experiences with each other.

Only thing that i have done is:

~$cd jetracer

jetracer file is a git clone from your link

~/jetracer$ sudo python3 setup.py install

After this command some modules have been installed (also adafriut_servokit) but I still get the same error in jupyter ā€œNo module named ā€˜adafruit_servokitā€™ā€. Maybe it is problem with the notebook itself?

I agree. My email is raelaughnan@gmail.com. Iā€™ll try out some things today and let you know if anything works. So glad I am not the only one struggling with this.
