Restore callbacks states

[ghost]

https://pytorch-lightning.readthedocs.io/en/latest/common/weights_loading.html#restoring-training-state

In this last example, how to access callbacks after restoration? Is there something like, restored_trainer.restored_callback_states? I'm asking because the best_path_model can only be accessed if we have access to the model_checkpoint_callback.

You could do trainer.callbacks to access all callbacks.
