valdation_epoch_end won't log if no logging is done in validation_step
🐛 Bug
@edenlightning looks like setting both logger=False and prog_bar=False won't do anything. If this is intended, maybe we should add a warning or something.
Also saw another issue, if I don't log anything in validation_step then logged values in validation_epoch_end won't be logged too even if we set logger=True. Updated the notebook attatched above for the same to verify.
