composer.models

The models module contains the ComposerModel base class along with reference implementations of many common models. Additionally, it includes task-specific convenience ComposerModels that wrap existing Pytorch models with standard forward passes and logging to enable quick interaction with the Trainer.

See Composer Model for more details.
