Jan 29, 2022 · Callback.__call__ [source] Call self. {event_name} if it's defined. One way to define callbacks is through subclassing: Another way is by passing the callback function to the constructor: Callback s provide a shortcut to avoid having to write self.learn.bla for any bla attribute we seek; instead, just write self.bla.

Jun 21, 2021 · The above setup, although very crude, works for the simple setup I have. It assumes access to an MLflow server with accessible URI (TRACKING_URI). One caveat is that metric values tend to be empty for the first couple of epochs and, with more understanding of fastai Callbacks and recorder, I might be able to track down. Happy Deep Learning
