I am currently working on something very similar to the donkey car project but with Pytorch instead of Tensorflow. Just wanted to share if you are interested in contributing or building something similar!
The donkeycar project seems pretty mature. Why not try helping port that to Nano instead of writing your own thing? It’ll probably be a lot easier and you’ll likely get more takers ;) just my .02
after a google, it appears there is already some work done for you.
