Tophat

Tophat is a factorization-based recommendation engine built using TensorFlow.

Installation

Installing from PyPi:

pip install top-hat

Installing the master branch from github in development mode, run:

git clone git@github.com:gilt/tophat.git
cd tophat
pip install -e .

Note that by default, installation assumes you already have TensorFlow installed. However, if you need, you can include the installation of TensorFlow in the setup extras as following: (choose the one that's right for you)

# CPU pypi
pip install top-hat[tf]

# GPU pypi
pip install top-hat[tf_gpu]

# CPU local dev
pip install -e .[tf]

# GPU local dev
pip install -e .[tf_gpu]

Docker Images

There are two provided Dockerfiles: Dockerfile and Dockerfile.gpu. The latter gpu variant requires nvidia-docker.

Tests

There are some minimal tests in tests/ which can all be run using pytest or python setup.py test.
