An open source neural recommender library

Main Contributors: Bin Wu, Zhongchuan Sun, Xiangnan He, Xiang Wang, & Jonathan Staniforth

NeuRec is a comprehensive and flexible Python library for recommender systems that includes a large range of state-of-the-art neural recommender models. This library aims to solve general, social and sequential (i.e. next-item) recommendation tasks, using the Tensorflow library to provide 33 models out of the box. NeuRec is open source and available under the MIT license.


  • Cross platform - run on any operating system with the available Docker images;
  • State-of-the-art - 33 neural recommender models available out of the box;
  • Flexible configuration - easily change the configuration settings to your exact requirements;
  • Easy expansion - quickly include models or datasets into NeuRec;
  • Fast execution - naturally support GPU, with a mutli-thread evaluator;
  • Detailed documentation - extensive documentation available as Jupyter notebooks in tutorial.ipynb.


The architecture of NeuRec is shown in the diagram below:

Quick Start

Firstly, download this repository and unpack the downloaded source to a suitable location.

Secondly, go to './NeuRec' and compline the evaluator of cpp implementation with the following command line:

python build_ext --inplace

If the compilation is successful, the evaluator of cpp implementation will be called automatically. Otherwise, the evaluator of python implementation will be called.

Note that the cpp implementation is much faster than python.

Thirdly, specify dataset and recommender in configuration file

Finally, run in IDE or with command line:



The short introduction to NeuRec is described in tutorial.ipynb
