기반 클래스: lightning.pytorch.callbacks.callback.Callback

Create a simple callback on the fly using lambda functions.

매개변수: **kwargs¶ – hooks supported by Callback

Example:

>>> from lightning.pytorch import Trainer
>>> from lightning.pytorch.callbacks import LambdaCallback
>>> trainer = Trainer(callbacks=[LambdaCallback(setup=lambda *args: print('setup'))])
