This post is a tutorial for loading data with FastAI. The interface has changed a lot since I originally wrote a FastAI data tutorial, so I deleted that one and I’m starting from scratch and making a brand new one. I’ll try to keep this up-to-date with the latest version. FastAI seems to be quite stable at the moment, so hopefully this will continue to work with the latest version.

Why is modern architecture so ugly?

Apple’s M1 chips were released to much fanfare and some very impressive benchmarks. Unfortunately, all these gains don’t come for free. The downside of such a significant change is that it causes incompatibility issues. And because the basic CPU and instruction set are different, there are a lot of thorny issues. In this post, I’ll walk through some I ran into when installing standard data science libraries and how I solved them. In the end, I was able to get everything working, although it took quite a bit of patience. Hopefully, these incompatibilities get resolved relatively soon, but, until then, here’s my guide to help you out.
