pytorch_pfn_extras.training.triggers.MaxValueTrigger#

class pytorch_pfn_extras.training.triggers.MaxValueTrigger(key, trigger=(1, 'epoch'))#

Bases: BestValueTrigger

Trigger invoked when specific value becomes maximum.

For example you can use this trigger to take snapshot on the epoch the validation accuracy is maximum.

Parameters:

  • key (str) – Key of value. The trigger fires when the value associated with this key becomes maximum.

  • trigger (TriggerLike) – Trigger that decides the comparison interval between current best value and new value. This must be a tuple in the form of <int>, 'epoch' or <int>, 'iteration' which is passed to IntervalTrigger.

Methods

may_fire(iteration, epoch_length)

Flags if the trigger may fire at the current iteration
