dgNN

Note: We'd like to inform our users that dgNN will no longer be actively maintained. Our development efforts will focus on integrating its features and functionalities into dgSPARSE-Lib. We believe this consolidation will provide a more streamlined and efficient experience for our user community. Thank you for your continued support.

dgNN is a high-performance backend for GNN layers with DFG (Data Flow Graph) level optimization. dgNN project is based on PyTorch.

How to install

through pip

pip install dgNN

If pip couldn't build dgNN, we recommend you to build dgNN from source.

git clone git@github.com:dgSPARSE/dgNN.git
cd dgNN
bash install.sh

Requirement

CUDA toolkit >= 10.0
pytorch >= 1.7.0
scipy
dgl >= 0.7 (We use dgl's dataset)
ninja

We prepare a docker to run our implementation. You could run our dgNN in a docker container.

cd docker
docker build -t dgNN:v1 -f Dockerfile .
docker run -it dgNN:v1 /bin/bash

Examples

Our training script is modified from DGL. Now we implements three popular GNN models.

Run GAT

DGL Code

cd dgNN/script/train
python train_gatconv.py --num-hidden=64 --num-heads=4 --dataset cora --gpu 0

Run Monet

DGL Code

cd dgNN/script/train
python train_gmmconv.py --n-kernels 3 --pseudo-dim 2 --dataset cora --gpu 0

Run PointCloud

We use modelnet40-sampled-2048 data in our PointNet. DGL Code

cd dgNN/script/train
python train_edgeconv.py

Collaborative Projects

CogDL is a flexible and efficient graph-learning framework that uses GE-SpMM to accelerate GNN algorithms. This repo is implemented in CogDL as a submodule.
