What problem does it solve?

HuggingFace Accelerate removes the complexity of setting up distributed training by giving you one simple API for running the same PyTorch code across single GPU, multi-GPU, and multi-node environments.

Core Features & Use Cases

  • Unified distributed training API: Switch between DDP, DeepSpeed, and FSDP without rewriting your training loop.
  • Automatic device placement and mixed precision: Handle mixed precision modes like FP16, BF16, and FP8, plus correct backward handling.
  • Practical workflows for real training: Enable gradient accumulation, configure DeepSpeed ZeRO stages, and use Megatron-LM plugins for tensor/pipeline parallelism.

Use case: You have a working single-GPU PyTorch script and need to scale it to 8 GPUs with BF16 mixed precision and optionally DeepSpeed ZeRO, without maintaining separate launcher logic and device-transfer code paths.

Quick Start

Tell the AI to configure Accelerate for your setup and launch distributed training for your script in one run.

Frequently Asked Questions about huggingface-accelerate

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

FAQPage Schema
How do I scale a single-GPU PyTorch script to multi-GPU training without rewriting my code?▼

Distributed training can be simplified by using a unified API that applies the same PyTorch code across single-GPU, multi-GPU, and multi-node environments. You use an Accelerator to prepare your model and dataloader, avoiding separate launcher logic.

What's the best way to enable BF16 mixed precision and DeepSpeed ZeRO in my training loop?▼

Mixed precision and DeepSpeed ZeRO are enabled through a unified configuration. You specify mixed_precision modes like BF16 and apply strategy-specific plugins during the prepare workflow, ensuring correct backward handling without maintaining custom device-transfer code.

Can I switch between FSDP and DeepSpeed for distributed training using the same PyTorch script?▼

Yes, you can switch between FSDP and DeepSpeed without rewriting your training loop. A unified distributed training API applies strategy-specific plugins to handle the underlying transfers and configurations automatically.

When do I need to use FSDP or Megatron-LM plugins for PyTorch distributed training?▼

You need FSDP or Megatron-LM plugins when scaling models across multiple GPUs or nodes. FSDP handles sharding for large models, while Megatron-LM plugins provide tensor and pipeline parallelism for massive scale training workflows.

Does HuggingFace Accelerate handle gradient accumulation automatically in multi-node environments?▼

Yes, HuggingFace Accelerate handles gradient accumulation automatically. It integrates this functionality into the unified API, allowing you to enable gradient accumulation alongside mixed precision and multi-node training configurations.
