[LF Feedback] Post on custom fastai callbacks

Hi everyone,

I wrote a blogpost on how to write custom fastai Callbacks and I’m looking for any kind of feedback (writing style, topic, factual accuracy). I found two previous posts that provided a good introduction to Callbacks in general, but I was missing the more “get your hands dirty” walk-through of it, so I wrote something up myself. I’ve also included a stand-alone Jupyter notebook that can be used as some kind of skeleton I suppose.

Woud be happy to get some feedback!


Also, if anyone has a link to the docs on LearnerCallback that’d be great, I couldn’t find it (aside from the docstring in the code itself).
