The signature of Callback.on_train_epoch_end has changed i

[talhaanwarch]

I am getting this warning.

ightningDeprecationWarning: The signature of `Callback.on_train_epoch_end` has changed in v1.3. `outputs` parameter has been removed. Support for the old signature will be removed in v1.5 "The signature of `Callback.on_train_epoch_end` has changed in v1.3."

What does that mean? and how to avoid this

Have you implemented a callback which implements the on_train_epoch_end method? Does it contain an outputs parameter in the method signature?

If so, you should remove outputs as the callback method. if you need the per-step outputs to post-process in the callback, see here for some options: https://github.com/PyTorchLightning/pytorch-lightning/blob/e5d9e21dea0caa625f26f5cec169195ecbe5e930/pytorch_lightning/callbacks/base.py#L112-L120

I am not using on_train_epoch_end method
Here is my function

def validation_step(self,batch,batch_idx):
   
    self.log('val_dice', dice, on_step=False, on_epoch=True,prog_bar=True)
    self.log('val_loss', loss, on_step=False, on_epoch=True,prog_bar=True)
    return loss
