For example, you cannot run the same script with the same batch size across TPU, multi-GPU, and single-GPU with Accelerate and expect your A community member has taken the idea and expanded it further, allowing you to filter models directly and see if you can run a particular LLM given GPU constraints and LoRA configurations. To do so you should pass in a gradient_accumulation_steps parameter to Accelerator, dictating the number of steps to perform before each call to step() and how to automatically adjust the loss during the call to backward(): All of the scripts can be run on multiple GPUs by providing the path of an 🤗 Accelerate config file when calling accelerate launch. ) and available hardware. 4 (Singularity container based on Ubuntu 22. You’ll learn how to modify your code to have it work with the API seamlessly, how to launch your script properly, and more! These Before we can browse the rest of the notebook, we need to install the dependencies: this example uses datasets and transformers. To use TPUs on colab, we need to install torch_xla and the last line install accelerate from source since we the features 🚀 A simple way to launch, train, and use PyTorch models on almost any device and distributed configuration, automatic mixed precision (including fp8), and easy-to-configure FSDP and DeepSpeed suppo Custom Configurations As briefly mentioned earlier, accelerate launch should be mostly used through combining set configurations made with the accelerate config command. Users often want to send a number of different prompts, each to a different GPU, and then get the results back. Custom Configurations As briefly mentioned earlier, accelerate launch should be mostly used through combining set configurations made with the accelerate config command. 34. Official Accelerate Examples: Basic Examples These examples showcase the base features of Accelerate and are a great starting point Barebones NLP example Quicktour There are many ways to launch and run your code depending on your training environment (torchrun, DeepSpeed, etc. from accelerate import Accelerator accelerator = Accelerator () This should happen as early as possible in your training script as it will initialize everything necessary for distributed training. Get started by installing 🤗 Accelerate: Then import and create an Accelerator object. backward() with accelerator. The training on a single machine works fine, but takes too long so i want to utilize multiple System Info Accelerate 0. yaml file in your cache Hi, I’m surprised not to find any info on this yet, but I guess I’m the first one to ask: Is there any way to make Accelerate work with a PyTorch Lightning based code? (Or a recommended way to convert from the latter to the former?) Up until posting this, I’ve been assuming the answer is “No”, and have begun “ripping out” all my Lightning stuff and Letting Accelerate handle gradient accumulation All that is left now is to let Accelerate handle the gradient accumulation for us. These examples showcase the base features of Accelerate and are a great starting point. Accelerate offers a unified interface for launching and training on different distributed setups, allowing you to 🚀 A simple way to launch, train, and use PyTorch models on almost any device and distributed configuration, automatic mixed precision (including fp8), and easy-to-configure FSDP and DeepSpeed suppo Save and load Accelerate can also save and load a model once training is complete or you can also save the model and optimizer state which could be useful for resuming training. from accelerate import Accelerator accelerator = Accelerator() model, optimizer, training_dataloader, scheduler = accelerator. The Command When using accelerate estimate-memory, you need to pass in the name of the model you want to use, potentially the Overview Welcome to the 🤗 Accelerate tutorials! These introductory guides will help catch you up to speed on working with 🤗 Accelerate. MPI If your distributed CPU training job using MPI is hanging, ensure that you have passwordless SSH setup (using keys) between the nodes. 04) Information The official example scripts My own modified scripts Tasks One of the scripts in the examples/ folder of Accelerate or an officially sup 🚀 A simple way to launch, train, and use PyTorch models on almost any device and distributed configuration, automatic mixed precision (including fp8), and easy-to-configure FSDP and DeepSpeed suppo Accelerate Run your raw PyTorch training script on any kind of device Features 🤗 Accelerate provides an easy API to make your scripts run with mixed precision and on any kind of distributed setting (multi-GPUs, TPUs etc. It serves at the main entrypoint for the API. You don’t need to indicate the kind of environment you are in (just one machine with a GPU, one match with several GPUs, several machines with multiple GPUs or a TPU), the library will Accelerate Run your raw PyTorch training script on any kind of device Features 🤗 Accelerate provides an easy API to make your scripts run with mixed precision and on any kind of distributed setting (multi-GPUs, TPUs etc. In this tutorial, we’ll show this method for GPT2 across two GPUs. You’ll learn how to modify your code to have it work with the API seamlessly, how to launch your script properly, and more! These . This command wraps around all of the different commands needed to launch your script on various platforms, without replace loss. The entire guts of the trainer was removed and replaced 1:1 with accelerate. Before you proceed, please make sure you have the 🚀 A simple way to launch, train, and use PyTorch models on almost any device and distributed configuration, automatic mixed precision (including fp8), and easy-to-configure FSDP and DeepSpeed suppo Evaluating and comparing the performance from different setups can be quite tricky if you don’t know what to look for. It serves at the main entry point for the API. Overview Welcome to the Accelerate tutorials! These introductory guides will help catch you up to speed on working with Accelerate. gather to gather all predictions and labels before storing them in our list of predictions/labels, truncate predictions Accelerate is a library from Hugging Face that simplifies turning PyTorch code for a single GPU into code for multiple GPUs, on single or multiple machines. Otherwise there are no external changes needed, as mentioned before. 5, hanging processes have been reported. prepare(+ model, optimizer, training_dataloader, scheduler + ) for batch in To illustrate how you can use this with Accelerate, we have created an example zoo showcasing a number of different models and situations. Quick adaptation of your code To quickly adapt your script to work on any kind of setup with 🤗 Accelerate just: Initialize an Accelerator object (that we will call accelerator throughout this page) as early as possible in your script. It "just works". The Accelerator will automatically Examples showcasing AWS SageMaker integration of 🤗 Accelerate. yaml file in your cache folder Currently, Accelerate supports the following config through the CLI: fsdp_sharding_strategy: [1] FULL_SHARD (shards optimizer states, gradients and parameters), [2] SHARD_GRAD_OP (shards optimizer states and gradients), [3] NO_SHARD (DDP), [4] HYBRID_SHARD (shards optimizer states, gradients and parameters within each node while each node has full copy), Save and load Accelerate can also save and load a model once training is complete or you can also save the model and optimizer state which could be useful for resuming training.
