Introduction

Welcome to Alpenglow introduction!

Alpenglow is an open source recommender systems research framework, aimed at providing tools for rapid prototyping and evaluation of algorithms for streaming recommendation tasks.

The framework is composed of a large number of components written in C++ and a thin python API for combining them into reusable experiments, thus enabling ease of use and fast execution at the same time. The framework also provides a number of preconfigured experiments in the alpenglow.experiments package and various tools for evaluation, hyperparameter search, etc.

Requirements

Anaconda environment with Python >= 3.5

Installing

conda install -c kdomokos alpenglow

Installing from source on Linux

cd Alpenglow
conda install libgcc
pip install .

Development

  • For faster recompilation, use export CC=”ccache cc”
  • To enable compilation on 4 threads for example, use echo 4 > .parallel
  • Reinstall modified version using pip install --upgrade --force-reinstall --no-deps .
  • To build and use in the current folder, use pip install --upgrade --force-reinstall --no-deps -e . and export PYTHONPATH=$(pwd)/python:$PYTHONPATH
