## Overview

PyTorch is an open-source framework for deep-learning research and model development. Developers represent data as tensors, compute gradients through automatic differentiation and build training loops with neural-network modules, optimizers and data loaders. Supported CPUs and accelerators run models, with compilation and distributed capabilities extending training. Models, data, weights and a compatible runtime must be supplied separately.
