Model checkpointing for sub-epoch frequency
❓ Questions and Help
What is your question?
In my Trainer I have val_check_interval=0.25, which is great and I can see that the validation loop is run 4 times per epoch as expected.
Is there a way for ModelCheckpoint to use the validation checks to trigger model saving at a sub-epoch frequency? I can see (by setting verbose=True) that the check is only done on epoch end
What's your environment?
