description Overview

PyTorch Lightning

Built on PyTorch, PyTorch Lightning organizes deep-learning projects around model code while handling much of the repeated work involved in training. A LightningModule contains the model's training behavior, while the Trainer manages execution. That separation lets researchers and engineers spend more attention on architecture and experiments without writing every training loop from scratch. Exist...
