Hi @songyuc , thanks for your contribution. One thing to note is that MMEngine support adding additional custom hook methods so this logic for printing hook information is a little different from MMCV.

mmengine/mmengine/runner/runner.py

Lines 1735 to 1749 in 79c8d73

	def call_hook(self, fn_name: str, **kwargs) -> None:
	"""Call all hooks.
	Args:
	fn_name (str): The function name in each hook to be called, such as
	"before_train_epoch".
	**kwargs: Keyword arguments passed to hook.
	"""
	for hook in self._hooks:
	# support adding additional custom hook methods
	if hasattr(hook, fn_name):
	try:
	getattr(hook, fn_name)(self, **kwargs)
	except TypeError as e:
	raise TypeError(f'{e} in {hook}') from None
