Installation

MMF has been tested on Python 3.7+ and PyTorch 1.6. We recommend using a conda environment to install MMF.

Creating a conda environment [Optional]

Assuming you have conda installed, run:

conda create -n mmf python=3.7
conda activate mmf

To install from source do:

git clone https://github.com/facebookresearch/mmf.git
cd mmf
pip install --editable .

MMF can be installed using pip with the following command:

pip install --upgrade --pre mmf

Use this if:

You are using MMF as a library and not developing inside MMF. Take a look at the extending MMF tutorial.
You want easy installation and don't care about up-to-date features. Note that pip packages are always outdated relative to installing from source.

Alternatively, to install latest MMF version from GitHub using pip, use

pip install git+https://github.com/facebookresearch/mmf.git

If you are on Windows, run the pip install commands with an extra argument like:

pip install -f https://download.pytorch.org/whl/torch_stable.html --editable .

MMF uses pytest for testing. To verify everything and run tests at your end do:

pytest ./tests/
