RecBole is developed based on Python and PyTorch for reproducing and developing recommendation algorithms in a unified, comprehensive and efficient framework for research purpose. Our library includes 53 recommendation algorithms, covering four major categories:

  • General Recommendation
  • Sequential Recommendation
  • Context-aware Recommendation
  • Knowledge-based Recommendation

We design a unified and flexible data file format, and provide the support for 27 benchmark recommendation datasets. A user can apply the provided script to process the original data copy, or simply download the processed datasets by our team.

Feature

  • General and extensible data structure. We design general and extensible data structures to unify the formatting and usage of various recommendation datasets.

  • Comprehensive benchmark models and datasets. We implement 53 commonly used recommendation algorithms, and provide the formatted copies of 27 recommendation datasets.

  • Efficient GPU-accelerated execution. We optimize the efficiency of our library with a number of improved techniques oriented to the GPU environment.

  • Extensive and standard evaluation protocols. We support a series of widely adopted evaluation protocols or settings for testing and comparing recommendation algorithms.

RecBole News

11/03/2020: We release the first version of RecBole v0.1.1.

Installation

RecBole works with the following operating systems:

  • Linux
  • Windows 10
  • macOS X

RecBole requires Python version 3.6 or later.

RecBole requires torch version 1.6.0 or later. If you want to use RecBole with GPU, please ensure that CUDA or cudatoolkit version is 9.2 or later. This requires NVIDIA driver version >= 396.26 (for Linux) or >= 397.44 (for Windows10).

Install from conda

conda install -c aibox recbole

Install from pip

pip install recbole

Install from source

git clone https://github.com/RUCAIBox/RecBole.git && cd RecBole
pip install -e . --verbose

Quick-Start

With the source code, you can use the provided script for initial usage of our library:

python run_recbole.py

This script will run the BPR model on the ml-100k dataset.

Typically, this example takes less than one minute. We will obtain some output like:

If you want to change the parameters, such as learning_rate, embedding_size, just set the additional command parameters as you need:

python run_recbole.py --learning_rate=0.0001 --embedding_size=128

If you want to change the models, just run the script by setting additional command parameters:

python run_recbole.py --model=[model_name]
