OpenHGNN

| English | 中文 |

This is an open-source toolkit for Heterogeneous Graph Neural Network(OpenHGNN) based on DGL [Deep Graph Library] and PyTorch. We integrate SOTA models of heterogeneous graph.

Key Features

• Easy-to-Use: OpenHGNN provides easy-to-use interfaces for running experiments with the given models and dataset. Besides, we also integrate optuna to get hyperparameter optimization.
• Extensibility: User can define customized task/model/dataset to apply new models to new scenarios.
• Efficiency: The backend dgl provides efficient APIs.

Get Started

Requirements and Installation

• Python >= 3.6

• PyTorch >= 1.7.1

• DGL >= 0.7.0

• CPU or NVIDIA GPU, Linux, Python3

1. Python environment (Optional): We recommend using Conda package manager

conda create -n openhgnn python=3.7
source activate openhgnn

2. Pytorch: Install PyTorch. For example:

# CUDA versions: cpu, cu92, cu101, cu102, cu101, cu111
pip install torch==1.8.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html

3. DGL: Install DGL, follow their instructions. For example:

# CUDA versions: cpu, cu101, cu102, cu110, cu111
pip install --pre dgl-cu101 -f https://data.dgl.ai/wheels-test/repo.html

4. OpenHGNN and other dependencies:

git clone https://github.com/BUPT-GAMMA/OpenHGNN
cd OpenHGNN
pip install -r requirements.txt

Running an existing baseline model on an existing benchmark dataset

python main.py -m model_name -d dataset_name -t task_name -g 0 --use_best_config --load_from_pretrained

usage: main.py [-h] [--model MODEL] [--task TASK] [--dataset DATASET]
[--gpu GPU] [--use_best_config]

optional arguments:

-h, --help show this help message and exit

--model -m name of models

--task -t name of task

--dataset -d name of datasets

--gpu -g controls which gpu you will use. If you do not have gpu, set -g -1.

--use_best_config use_best_config means you can use the best config in the dataset with the model. If you want to set the different hyper-parameter, modify the openhgnn.config.ini manually. The best_config will override the parameter in config.ini.

--use_hpo Besides use_best_config, we give a hyper-parameter example to search the best hyper-parameter automatically.

--load_from_pretrained will load the model from a default checkpoint.

e.g.:

python main.py -m GTN -d imdb4GTN -t node_classification -g 0 --use_best_config

Note: If you are interested in some model, you can refer to the below models list.

Refer to the docs to get more basic and depth usage.
