Hi @mike.moloch,
I’m happy to hear that you are finding the Paperspace images useful and easy to use!
As for the Fast.ai container specifically, you can find the GitHub repo here: GitHub - Paperspace/fastai-docker: Fast.AI course complete docker container for Paperspace and Gradient.
A lot of the packages in our container come from a pip install of fastai so it may be helpful to look at the Fast.ai Git repo as well: GitHub - fastai/fastai: The fastai deep learning library
