optimizer_step(optimizer, closure, model=None, **kwargs)[source]¶

Performs the actual optimizer step.

Parameters

optimizer¶ (Optimizer) – the optimizer performing the step
closure¶ (Callable[[], Any]) – closure calculating the loss value
model¶ (Union[LightningModule, Module, None]) – reference to the model, optionally defining optimizer step related hooks
**kwargs¶ – Keyword arguments to optimizer.step

Return type

Any

setup(trainer)[source]¶

Setup plugins for the trainer fit and creates optimizers.

Parameters: trainer¶ (Trainer) – the trainer instance
Return type: None

setup_optimizers(trainer)[source]¶

Creates optimizers and schedulers.

Parameters: trainer¶ (Trainer) – the Trainer, these optimizers should be connected to
Return type: None
