I would like to save a checkpoint every time a validation loop ends. I set up the val_check_interval to be 0.2 so I have 5 validation loops during each epoch but the checkpoint callback saves the model only at the end of the epoch. I couldn’t find an easy (or hard) way to save the model after each validation loop. It seems a bit strange cause, I think, the main purpose of the validation loop is to save a checkpoint.
What is the simplest way of doing that?
Thank you,
Gilad
