question: Does LightningLite still support various callbacks?
context: LightningModule can be coupled with various callbacks? I wonder if it is possible LightningLite can also reuse those callbacks, such as wandb, checkpoint?
answer: I don't think they are because the hooks in callbacks are just some code injections that are supposed to run at a certain point where lightning defines the training loops/validation loops but in LightningLite user defines the training loop, so it won't be possible. Although in the case of wandb for eg you can use their native API to log the stuff.
