Hi Shaun,
I’m doing the fast.ai course now, and using GCE. In my experience, the fast.ai code is still very much ‘research code’, and not hardened enough to very well outside of the specific problem, dataset, and algorithm used by fast.ai. I’ve been pretty frustrated by it! If you dig deeper into the fast.ai codebase, its not that hard to see its just a few wrappers for dataset loading and some cyclical learning rate stuff. Good luck!
