pylibffm 0.4.0

A library wrapping libffm

pylibffm

pylibffm is a wrapper around libffm to allow using scipy and numpy arrays as input. pylibffm requires SSE and openmp.

Installing

If you're running python 3.7~3.11 on linux

pip install pylibffm

Otherwise

git clone --recurse-submodules https://github.com/Sinacam/pylibffm
cd pylibffm
make
pip install .

Currently, the distribution is incredibly hacky and cannot be pip installed from source. Windows build support is lacking, but code should be correct.

Documentation

The API consists of

• train
• load
• Model
  • Model.save
  • Model.predict
• make_bin
• train_with_bin

Use help or read their docstring for their usage.

Diff with libffm

To be deterministic, set openmp threads to 1. For pylibffm, do

OMP_NUM_THREADS=1 python <script>.py

For libffm, run with -s 1 (the default). This should yield identical models.
