The experiments in the paper were run on an Nvidia GTX1080Ti. If you have other GPUs, please check your GPU and cuda compatibility.
We set up an Anaconda environment with Python 3.8
conda create -n ibmb python=3.8
conda activate ibmb
We use pytorch 1.10.1 with cudatoolkit 11.3
conda install pytorch==1.10.1 cudatoolkit=11.3 -c pytorch -c conda-forge
Install PyG 2.0.3. Feel free to use other versions, just be careful of some updates in classes and keywords.
pip install https://data.pyg.org/whl/torch-1.10.0%2Bcu113/torch_scatter-2.0.9-cp38-cp38-linux_x86_64.whl
pip install https://data.pyg.org/whl/torch-1.10.0%2Bcu113/torch_sparse-0.6.13-cp38-cp38-linux_x86_64.whl # please do not use older versions < 0.6.12
pip install torch-geometric==2.0.3
Other packages
pip install ogb
pip install sacred
pip install seml
pip install parallel-sort==0.0.3 # please do not use new versions
pip install python-tsp
pip install psutil
pip install numba
We provide a couple of demo configs to play with.
To replicate Table 7 and Figure 3, run with the yaml files under configs/main_exps/, e.g.
python run_ogbn.py with configs/main_exps/gcn/arxiv/ibmb_node.yaml
To replicate Figure 2, run with the yaml files under configs/infer. You have to provide grid search parameters yourself. We recommend using seml to tune the hyperparameters in large scale. e.g.
python infer.py with configs/infer/gcn/arxiv/ibmb_node.yaml
See the paper's appendix for more information about tuning hyperparameters of IBMB and the baselines.
For the largest dataset ogbn-papers100M, we recommend you to run the notebook dataprocess_100m.ipynb first then proceed with run_papers100m.py. In order to perform full graph inference on such large dataset, we provide some tricks of tensor chunking, see run_papers100m_full_infer.py for more details. You need at least 256GB RAM for the ogbn-papers100M experiments.
