What problem does it solve?

Accelerate removes the complexity of setting up distributed training by providing a unified API that can run the same training code across single GPU, multi-GPU, and multi-node environments without rewriting core logic.

Core Features & Use Cases

Unified distributed API: Prepare model/optimizer/dataloader once and let Accelerate handle device placement, process launching, and synchronization for DDP/DeepSpeed/FSDP/Megatron-style workflows.
Mixed precision support: Enable FP16, BF16, and FP8 with automatic autocast and backward handling for better performance and lower memory usage.
Plug-in integrations for scalability: Use DeepSpeed ZeRO (2/3) or FSDP sharding to scale larger models while managing memory pressure.
Use case: Turn an existing PyTorch training script into a multi-GPU job by running a single launch command after adding a minimal Accelerator setup and replacing loss backward with accelerator-aware backward.

Quick Start

Run your existing training script with distributed support by executing: accelerate launch train.py.

Frequently Asked Questions about huggingface-accelerate

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I add distributed training to an existing PyTorch script without rewriting core logic?▼

To add distributed training, define an Accelerator instance, prepare your model, optimizer, and dataloader, replace the loss backward call with accelerator.backward, and launch the script using accelerate launch. This abstracts device placement and process synchronization for multi-GPU and multi-node environments.

What is the best way to scale large PyTorch models across multiple GPUs while managing memory pressure?▼

Using distributed training with plug-in integrations like DeepSpeed ZeRO or FSDP sharding allows you to scale large models by splitting states across devices. This manages memory pressure by abstracting distributed synchronization through a unified API without altering your core training logic.

Does Hugging Face Accelerate support mixed precision training with FP16, BF16, or FP8?▼

Yes, mixed precision training is fully supported. You can enable FP16, BF16, and FP8 formats to achieve better performance and lower memory usage through automatic autocast and backward handling provided by the unified distributed API during model preparation.

Can I run the same PyTorch training code across single GPU, multi-GPU, and multi-node environments?▼

Yes, you can run the same training code across single GPU, multi-GPU, and multi-node environments. The unified distributed API handles device placement, process launching, and synchronization so you do not need to rewrite core logic for different hardware setups.

Do I need to manually configure process orchestration for DeepSpeed or FSDP sharding?▼

No, you do not need to manually configure process orchestration. The Accelerator instance prepares your components and handles process launching and distributed synchronization automatically when using backend integrations like DeepSpeed ZeRO or FSDP sharding.
