This is an open-source toolkit for Heterogeneous Graph Neural Network(OpenHGNN) based on DGL [Deep Graph Library] and PyTorch.

Last update: Jan 02, 2023

Overview

OpenHGNN

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

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 MODEL, -m MODEL name of models

--task TASK, -t TASK name of task

--dataset DATASET, -d DATASET name of datasets

--gpu GPU, -g GPU 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.

e.g.:

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

It is under development, and we release it in a nightly build version. For now, we just give some new models, such as HetGNN, NSHE, GTN, MAGNN, RSHN.

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.

    experiment.run()

Expected behavior

Minibatch training on a large heterograph

Environment

torch==1.12.1
dgl-cu113==0.9.0 # for CUDA support
openhgnn==0.3.0
Linux
Python 3.8.13

Additional context

the default minibatch sampler is MultiLayerFullNeighborSampler
the blocks is a list (line 164) and the expected input in the forward function of the model (e.g. SimpleHGN) is a hg(line 159)

for i, (input_nodes, seeds, blocks) in enumerate(loader_tqdm):
    blocks = [blk.to(self.device) for blk in blocks]
    ...
    logits = self.model(blocks, emb)[self.category]

def forward(self, hg, h_dict):
    with hg.local_scope():
        hg.ndata['h'] = h_dict

关于HetGNN的emb顺序困惑

请教下在 x = self.model(blocks[0], input_features) 中返回的x 是dict 。他里面每种node_type 的emb 和blocks[0] 的入参的点的顺序如何对应？

我核对了以后发现并不是 blocks[0].srcnodes[node_type].data[dgl.NID] 所代表的节点顺序。

Help needed: Wanted behavior of Experiment.specific_trainerflow.get method and task/trainerflow registration

Hi, I am trying to create a new trainer flow, as well as a new task. I am struggling a bit and have a few questions: When I register them with @register_flow(str_flow) and @register_task(str_task), must str_taskand str_flowbe identical?
Because as my flow is not specific to a model, it is not in the specific_trainerflowdictionnary defined in the Experiment class. So the line 92 in experiment.py( trainerflow = self.specific_trainerflow.get(self.config.model, self.config.task) ) returns the key of the task as the trainerflow_key. Is this the wanted behavior?

Thanks!

it seems like there is no pap_m2v_emb key in paper nodes data， so how to fix it?

more error update: when I just make mp_emb_dim=0 to jump this line, more errors raise, such as no hidden_dim、mini_batch_flag ... defined in config, besides, when I successfully run this model, another exception was raised:

Do you have an updated version of the model？
