ray.train.ScalingConfig.from_placement_group_factory

classmethod ScalingConfig.from_placement_group_factory(pgf: PlacementGroupFactory) → ScalingConfig

Create a ScalingConfig from a Tune’s PlacementGroupFactory

Note that this is only needed for ResourceChangingScheduler, which modifies a trial’s PlacementGroupFactory but doesn’t propagate the changes to ScalingConfig. TrainTrainable needs to reconstruct a ScalingConfig from on the trial’s PlacementGroupFactory.
