openfl.callbacks.LambdaCallback#

class openfl.callbacks.LambdaCallback(on_round_begin=None, on_round_end=None, on_experiment_begin=None, on_experiment_end=None)[source]#

Custom on-the-fly callbacks.

This callback can be constructed with functions that will be called at the appropriate time during the life-cycle of a Federated Learning experiment. Certain callbacks may expect positional arguments, for example:

  • on_round_begin: expects round_num as a positional argument.

  • on_round_end: expects round_num as a positional argument.

Parameters:

  • on_round_begin – called at the beginning of every round.

  • on_round_end – called at the end of every round.

  • on_experiment_begin – called at the beginning of an experiment.

  • on_experiment_end – called at the end of an experiment.
