• model (Union[LightningModule, Module, None]) – reference to the model, optionally defining optimizer step related hooks

• **kwargs – Keyword arguments to to optimizer.step

Return type

Any

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
