๐พ Installation#
Composer is available with pip:
pip install mosaicml
as well as with Anaconda:
conda install -c mosaicml mosaicml
To include non-core dependencies that are required by some algorithms, callbacks, datasets, or models, the following installation targets are available:
pip install 'mosaicml[dev]': Installs development dependencies, which are required for running tests and building documentation.pip install 'mosaicml[deepspeed]': Installs Composer with support fordeepspeed.pip install 'mosaicml[nlp]': Installs Composer with support for NLP models and algorithms.pip install 'mosaicml[unet]': Installs Composer with support for Unet.pip install 'mosaicml[timm]': Installs Composer with support fortimm.pip install 'mosaicml[wandb]': Installs Composer with support forwandb.pip install 'mosaicml[all]': Install all optional dependencies.
For a developer install, clone directly:
git clone https://github.com/mosaicml/composer.git
cd composer
pip install -e ".[all]"
Note
For fast loading of image data, we highly recommend installing Pillow-SIMD. To install, vanilla pillow must first be uninstalled.
pip uninstall pillow && pip install pillow-simd
Pillow-SIMD is not supported for Apple M1 Macs.
Docker#
To simplify environment setup for Composer, we provide a set of pre-built Docker images.
Composer Images#
The mosaicml/composer images contain all Composer pre-installed with
all dependencies for both NLP and Vision models. They are built on top of the
mosaicml/pytorch_vision family of images.
(See the section on MosaicML PyTorch Images below.)
Note: Only the Dockerimage for most recent version of Composer will be maintained. We recommend using
mosaicml/composer:latest or mosaicml/composer:latest_cpu, which will always be up to date.

Note: For a lightweight installation, we recommended using a MosaicML PyTorch Image and manually installing Composer within the image.
PyTorch Images#
The mosaicml/pytorch images contain PyTorch preinstalled, without Composer.
The base flavor contains PyTorch pre-installed; the vision flavor also includes OpenCV, MM Segmentation, and FFCV dependencies.
To install composer, once inside the image, run pip install mosaicml.

Pillow-SIMD is installed by default in all images.
Pulling Images#
Pre-built images can be pulled from MosaicMLโs DockerHub Repository.
For example:
docker pull mosaicml/composer
