EarlyStopping override disrupts wandb logging frequency #19990
Description
Bug description
When an EarlyStopping callback would halt the training before min_epochs has elapsed, EarlyStopping is (correctly) overridden, and prints the warning message given below. However, at the exact step number when the warning was printed, WandbLogger suddenly begins logging the train metrics for every single batch. This results in slowed training and strange output graphs.
What version are you seeing the problem on?
v2.2
