I’m currently working on getting fastai up and running on the system. From the videos I’ve found about installing Pytorch, it can take upwards of 36+ hours. I let mine run for about 24 before deciding it froze. I tried again and just let it run - it eventually kept moving and finished, so be patient.
From what I’ve learned, the Pi is likely more capable of inference than training the models, I’ll have to post an update on the performance and see whether I can apply any TPU units like Google’s Coral to up some vision detection wants I have.
Alternate option is running Fedora and following this guide.
