WebJun 9, 2024 · Callbacks are basically programs that contain code that's run when it is required. When and what a callback should do is defined by using Callback Hooks, a few of them are on_epoch_end, on_validation_epoch_end, etc. You can maybe define a logic to monitor a metric, save a model, or various other cool stuff.

WebJan 27, 2024 · What is Pytorch Lightning? Lightning is a high-level python framework built on top of Pytorch. It was created by William Falcon, while he was doing his PhD. It was created for researchers, specifically for trying new deep learning models which involved research scaling, multi-GPU training, 16-bit precision and TPU. Why Lightning?
