Accelerate

Overview

Accelerate is a Python library that simplifies launching and training PyTorch models across various devices and distributed configurations. It provides automatic mixed precision (including fp8) and easy-to-configure FSDP and DeepSpeed support.

Best for

Best for
PyTorch developers who need to scale training from a single GPU to multi-node clusters with minimal code changes

Use cases

• Run PyTorch training on single or multiple GPUs with minimal code changes
• Enable mixed precision training (fp16, bf16, fp8) for faster model convergence
• Configure distributed training with FSDP or DeepSpeed without manual setup
