Save DataModule stateΒΆ
When a checkpoint is created, it asks every DataModule for their state. If your DataModule defines the state_dict and load_state_dict methods, the checkpoint will automatically track and restore your DataModules.
class LitDataModule(pl.DataModuler):
def state_dict(self):
# track whatever you want here
state = {"current_train_batch_index": self.current_train_batch_index}
return state
def load_state_dict(self, state_dict):
# restore the state based on what you tracked in (def state_dict)
self.current_train_batch_index = state_dict["current_train_batch_index"]
