gtrick: Bag of Tricks for Graph Neural Networks.

gtrick is an easy-to-use Python package that collects tricks for graph neural networks. It tests and provides powerful tricks to boost your models' performance.

Trick is all you need! (English Document | 中文介绍)

Library Highlights

  • Easy-to-use: All it takes is to add a few lines of code to apply a powerful trick, with as few changes to existing code as possible.
  • Verified Trick: All tricks implemented in gtrick are tested on our selected datasets. Only the tricks indeed improving a model's performance can be collected by gtrick.
  • Backend Free: We provide all tricks both in DGL and PyG. Whatever graph learning library you use, feel free to try it.

Installation

Note: This is a developmental release.

pip install gtrick

Quick Start

It is very easy to get started with gtrick. You can enhance your GNN model with only a few lines of code.
