1. Introduction

This repo summarizes papers I've read for machine learning on graphs. I'm also writing tutorials on zhihu.com and they're in Chinese.

2. Requirements

I use basic packages from Anaconda3 with Python 3.8.5. To make my life easier, I also use the following packages to implement models. Please see requirements.txt for the full list.

torch==1.7.0
torch_geometric==1.6.3
ogb==1.2.3
scikit-multilearn==0.2.0
