Sfttrainer multi gpu training. I'm running this with python train. Feb 1, 2024 · From what I've read SFTTrainer should support multiple GPUs just fine, but when I run this I see one GPU with high utilization and one with almost none: Expected behaviour would be that both get used during training and it would be about 2x as fast as single-GPU training. Jun 7, 2025 · This page details the training arguments, SFTTrainer setup, and training loop implementation in the unsloth_multi_gpu system. g. ". Prior to making this transition, thoroughly explore all the strategies covered in the Methods and tools for efficient training on a single GPU as they are universally applicable to model training on any number of GPUs Designed for high-performance and distributed environments, SFTTrainer supports: Single-GPU, multi-GPU, and multi-node training Distributed Data Parallel (DDP) and Fully Sharded Data Parallel (FSDP) strategies RDMA over Converged Ethernet (RoCE) for optimized multi-node communication Quickstart ¶ For you to start finetuning quickly, we directly provide a shell script for you to run without paying attention to details. 1 using SWIFT on multi-GPU RunPod infrastructure, with LoRA configuration, dataset preprocessing, and completion-only training. Mar 22, 2023 · This is in contrary to this discussion on their forum that says "The Trainer class automatically handles multi-GPU training, you don’t have to do anything special.

It covers the configuration parameters, optimization settings, and execution flow for distributed supervised fine-tuning (SFT) of large language models. 6 days ago · Highlights Trainers: Various fine-tuning methods are easily accessible via trainers like SFTTrainer, GRPOTrainer, DPOTrainer, RewardTrainer and more. py, which I think means Trainer uses DP? Mar 22, 2023 · This is in contrary to this discussion on their forum that says "The Trainer class automatically handles multi-GPU training, you don’t have to do anything special. It covers how PyTorch Distributed Data Parallel (DDP) is used to coordinate LLM fine-tuning across multiple GPUs, including process initialization, model loading strategies, and training execution flow. Apr 8, 2024 · Reproduction When running training using the transformers trainer, and setting device_map to auto, what is the default distributed training type that is used when the model is too large to fit on one GPU? (assume that I have not yet run accelerate config).

Efficient and scalable: Leverages 🤗 Accelerate to scale from single GPU to multi-node clusters using methods like DDP and DeepSpeed. Aug 21, 2023 · hi All, would you please give me some idea how I can run the attached code with multiple GPUs, with define number of 1,2? As I understand the trainer in HF always goes with gpu:0, but I need to specify the number of GPUs like 1,2. Sep 28, 2023 · I have a multi-host environment with the following GPU configuration: Host1: GPU1 Host2: GPU2 Host3: GPU3, GPU4 Host4: GPU5, GPU6 To make sure that all available GPUs are used for training I'm us If training a model on a single GPU is too slow or if the model’s weights do not fit in a single GPU’s memory, transitioning to a multi-GPU setup may be a viable option. . I although I have 4x Nvidia T4 GPUs Cuda is installed and my environment can see the available GPUs. Feb 1, 2024 · From what I've read SFTTrainer should support multiple GPUs just fine, but when I run this I see one GPU with high utilization and one with almost none: Expected behaviour would be that both get used during training and it would be about 2x as fast as single-GPU training. You need different hyperparameters for different types of training, e. chat_templates import get_chat_template from unsloth import FastLanguageModel, is_bfloat16_supported Jun 7, 2025 · Relevant source files This document details the core distributed training implementation in the unsloth_multi_gpu system. , single-GPU / multi-GPU training, full-parameter tuning, LoRA, or Q-LoRA. If you want to use Spectrum check the Appendix for more information. This config works for single-GPU training and for multi-GPU training with DeepSpeed (see Appendix for full command). environ["MASTER_ADDR Jul 29, 2024 · import torch from trl import SFTTrainer from datasets import load_dataset from transformers import TrainingArguments, TextStreamer from unsloth.
