Callback is broken in fastai v2 official release?

I have a custom callback that was running fastai v2 (pre-release). I have since updated to the official v2 using pip install fastai==2.0.0.

However, the before_fit in my callback does not work anymore (it does not get called at all). Has anyone observed this too?

You may want to check the announcements thread. Most of the callback event names were changed.


Thanks. I missed the memo.
