`check_monitor_top`(current)
`on_epoch_end`(trainer, pl_module)	Deprecated since version v1.6.
`on_train_end`(trainer, pl_module)	Called when the train ends.
`on_train_start`(trainer, pl_module)	Called when the train begins.

Attributes#

state_key#

SaveBestState.state_key[source]#

Identifier for the state of the callback.

Used to store and retrieve a callback’s state from the checkpoint dictionary by checkpoint["callbacks"][state_key]. Implementations of a callback need to provide a unique state key if 1) the callback has state and 2) it is desired to maintain the state of multiple instances of that callback.

Return type:: str

Methods#

on_epoch_end#

SaveBestState.on_epoch_end(trainer, pl_module)[source]#: Deprecated since version v1.6: This callback hook was deprecated in v1.6 and will be removed in v1.8. Use on_<train/validation/test>_epoch_end instead.

Called when either of train/val/test epoch ends.

on_train_end#

SaveBestState.on_train_end(trainer, pl_module)[source]#: Called when the train ends.

on_train_start#

SaveBestState.on_train_start(trainer, pl_module)[source]#: Called when the train begins.
