This repository is based on MosaicML's llm-foundry under the Apache 2.0 license. We thank MosaicML for their foundational work in large language model training infrastructure!
llm-foundry uses uv to manage dependencies (uv is compatible with Conda environments, see the GPU section for an example of how to integrate the two). First clone the repository.
git clone https://github.com/LocalResearchGroup/llm-foundry.git
cd llm-foundryThen depending on your system, run one of the following commands to install the dependencies.
uv python pin 3.12
uv sync --dev --extra cpuFor Flash Attention support you'll need to install Cuda/Cuda Toolkit 12.4. The simplest way is to use Miniconda to install it.
# swap cuda-toolkit for cuda if you want to compile cuda packages
conda create -n llm-foundry python=3.12 uv cuda-toolkit -c nvidia/label/cuda-12.4.1 -c conda-forge
conda activate llm-foundry
# This sets uv to use the active Conda environment whether using uv or uv pip commands.
# You'll need to run this command every time you open a new terminal to run a uv command.
export UV_PROJECT_ENVIRONMENT="$CONDA_PREFIX"Or install system Cuda (not recommended).
With Cuda/Cuda Toolkit installed, then use uv to install the library:
uv python pin 3.12
uv sync --dev --extra gpu
# Install flash attention if you have a Ampere (RTX 30xx series) or newer GPU
uv sync --dev --extra gpu --extra flash --no-cacheuv python pin 3.12
uv sync --devIf you used uv to install other projects or are attempting to update llm-foundry to use new dependencies, append --refresh to the uv sync command to update the uv cache.
If you installed to the Conda environment, you can activate it with:
conda activate llm-foundryThen you'll need to manually run the following command:
export UV_PROJECT_ENVIRONMENT="$CONDA_PREFIX"to ensure uv uses the active Conda environment.
If you used uv to create a virtual environment, you can activate it with:

We highly recommend using our prebuilt Docker images. You can find them here: https://hub.docker.com/orgs/mosaicml/repositories.
The mosaicml/pytorch images are pinned to specific PyTorch and CUDA versions, and are stable and rarely updated.
The mosaicml/llm-foundry images are built with new tags upon every commit to the main branch.
You can select a specific commit hash such as mosaicml/llm-foundry:2.5.1_cu124-9867a7b or take the latest one using mosaicml/llm-foundry:2.5.1_cu124-latest.
Please Note: The mosaicml/llm-foundry images do not come with the llm-foundry package preinstalled, just the dependencies. You will still need to pip install llm-foundry either from PyPi or from source.
| Docker Image | Torch Version | Cuda Version | LLM Foundry dependencies installed? |

This assumes you already have PyTorch, CMake, and packaging installed. If not, you can install them with pip install cmake packaging torch.
To get started, clone the repo and set up your environment. Instructions to do so differ slightly depending on whether you're using Docker.
We strongly recommend working with LLM Foundry inside a Docker container (see our recommended Docker image above). If you are doing so, follow these steps to clone the repo and install the requirements.
git clone https://github.com/mosaicml/llm-foundry.git
cd llm-foundry
pip install -e ".[gpu]" # or `pip install -e .` if no NVIDIA GPU.If you choose not to use Docker, you should create and use a virtual environment.
git clone https://github.com/mosaicml/llm-foundry.git
cd llm-foundry
# Creating and activate a virtual environment
python3 -m venv llmfoundry-venv
source llmfoundry-venv/bin/activate
pip install cmake packaging torch # setup.py requires these be installed
pip install -e ".[gpu]" # or `pip install -e .` if no NVIDIA GPU.NVIDIA H100 GPUs have FP8 support; we have installed Flash Attention and Transformer i 8000 n our Docker images already (see above). If you are not using our Docker images, you can install these packages with:
pip install flash-attn --no-build-isolation
pip install git+https://github.com/NVIDIA/TransformerEngine.git@stableSee here for more details on enabling TransformerEngine layers and amp_fp8.
In our testing of AMD GPUs, the env setup includes:
git clone https://github.com/mosaicml/llm-foundry.git
cd llm-foundry
# Creating and activate a virtual environment
python3 -m venv llmfoundry-venv-amd
source llmfoundry-venv-amd/bin/activate
# installs
pip install cmake packaging torch
pip install -e . # This installs some things that are not needed but they don't hurt
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.4.2Lastly, install the ROCm enabled flash attention (instructions here).
Notes:
- We don't yet have a Docker image where everything works perfectly. You might need to up/downgrade some packages (in our case, we needed to downgrade to
numpy==1.23.5) before everything works without issue.
Support for LLM Foundry on Intel Gaudi devices is experimental, please use the branch habana_alpha and see the README on that branch which has install instructions and known issues.
For training and inference performance results on Intel Gaudi2 accelerators, see our blog: https://www.databricks.com/blog/llm-training-and-inference-intel-gaudi2-ai-accelerators
Note Make sure to go through the installation steps above before trying the quickstart! You can set env variables
LRG_USERandLRG_TAGSto tag your runs or add them tologgers.aim.tagsin yml config.
Here is an end-to-end workflow for preparing a subset of the C4 dataset, training an MPT-125M model for 10 batches, converting the model to HuggingFace format, evaluating the model on the Winograd challenge, and generating responses to prompts.
(Remember this is a quickstart just to demonstrate the tools -- To get good quality, the LLM must be trained for longer than 10 batches 😄)

If you have a write-enabled HuggingFace auth token, you can optionally upload your model to the Hub! Just export your token like this:
export HF_TOKEN=your-auth-tokenand uncomment the line containing --hf_repo_for_upload ... in the above call to inference/convert_composer_to_hf.py.
You can use the registry to customize your workflows without forking the library. Some components of LLM Foundry are registrable, such as models, loggers, and callbacks. This means that you can register new options for these components, and then use them in your yaml config.
To help find and understand registrable components, you can use the llmfoundry registry cli command.
We provide two commands currently:
llmfoundry registry get [--group]: List all registries, and their components, optionally specifying a specific registry. Example usage:llmfoundry registry get --group loggersorllmfoundry registry getllmfoundry registry find <group> <name>: Get information about a specific registered component. Example usage:llmfoundry registry find loggers wandb
Use --help on any of these commands for more information.
These commands can also help you understand what each registry is composed of, as each registry contains a docstring that will be printed out. The general concept is that each registry defines an interface, and components registered to that registry must implement that interface. If there is a part of the library that is not currently extendable, but you think it should be, please open an issue!
There are a few ways to register a new component:
You can specify registered components via a Python entrypoint if you are building your own package with registered components. This would be the expected usage if you are building a large extension to LLM Foundry, and going to be overriding many components. Note that things registered via entrypoints will override components registered directly in code.
For example, the following would register the MyLogger class, under the key my_logger, in the llm_foundry.loggers registry:
[build-system]
requires = ["setuptools>=42", "wheel"]
build-backend = "setuptools.build_meta"
[project]
name = "foundry_registry"
version = "0.1.0"
dependencies = [
"mosaicml",
"llm-foundry",
]
# Note: Even though in python code, this would be llmfoundry.registry.loggers,
# when specified in the entry_points, it has to be "llmfoundry_loggers". That is,
# the segments of the name should be joined by an _ in the entry_points section.
[project.entry-points."llmfoundry_loggers"]
my_logger = "foundry_registry.loggers:MyLogger"If developing new components via entrypoints, it is important to note that Python entrypoints are global to the Python environment. This means that if you have multiple packages that register components with the same key, the last one installed will be the one used. This can be useful for overriding components in LLM Foundry, but can also lead to unexpected behavior if not careful. Additionally, if you change the pyproject.toml, you will need to reinstall the package for the changes to take effect. You can do this quickly by installing with pip install -e . --no-deps to avoid reinstalling dependencies.
You can also register a component directly in your code:
from composer.loggers import LoggerDestination
from llmfoundry.registry import loggers
class MyLogger(LoggerDestination):
pass
loggers.register("my_logger", func=MyLogger)You can also use decorators to register components directly from your code:
from composer.loggers import LoggerDestination
from llmfoundry.registry import loggers
@loggers.register("my_logger")
class MyLogger(LoggerDestination):
passFor both the direct call and decorator approaches, if using the LLM Foundry train/eval scripts, you will need to provide the code_paths argument, which is a list of files need to execute in order to register your components. For example, you may have a file called foundry_imports.py that contains the following:
from foundry_registry.loggers import MyLogger
from llmfoundry.registry import loggers
loggers.register("my_logger", func=MyLogger)You would then provide code_paths to the train/eval scripts in your yaml config:
...
code_paths:
- foundry_imports.py
...One of these would be the expected usage if you are building a small extension to LLM Foundry, only overriding a few components, and thus don't want to create an entire package.
