How Attentive are Graph Attention Networks?

This repository is the official implementation of How Attentive are Graph Attention Networks?.

January 2022: the paper was accepted to ICLR'2022 !

Using GATv2

GATv2 is now available as part of PyTorch Geometric library!

from torch_geometric.nn.conv.gatv2_conv import GATv2Conv

https://pytorch-geometric.readthedocs.io/en/latest/modules/nn.html#torch_geometric.nn.conv.GATv2Conv

and also is in this main directory.

GATv2 is now available as part of DGL library!

from dgl.nn.pytorch import GATv2Conv

https://docs.dgl.ai/en/latest/api/python/nn.pytorch.html#gatv2conv

and also in this repository.

GATv2 is now available as part of Google's TensorFlow GNN library!

from tensorflow_gnn.graph.keras.layers.gat_v2 import GATv2Convolution

https://github.com/tensorflow/gnn/blob/main/tensorflow_gnn/docs/api_docs/python/gnn/keras/layers/GATv2.md

Code Structure

Since our experiments (Section 4) are based on different frameworks, this repository is divided into several sub-projects:

1. The subdirectory arxiv_mag_products_collab_citation2_noise contains the needed files to reproduce the results of Node-Prediction, Link-Prediction, and Robustness to Noise (Tables 2a, 3 and Figure 4).
2. The subdirectory proteins contains the needed files to reproduce the results of ogbn-proteins in Node-Prediction (Table 2b).
3. The subdirectory dictionary_lookup contains the need files to reproduce the results of the DictionaryLookup benchmark (Figure 3).
4. The subdirectory tf-gnn-samples contains the needed files to reproduce the results of the VarMisuse and QM9 datasets (Table 1 and Table 4).

Requirements

Each subdirectory contains its own requirements and dependencies.

Generally, all subdirectories depend on PyTorch 1.7.1 and PyTorch Geometric version 1.7.0 (proteins depends on DGL version 0.6.0). The subdirectory tf-gnn-samples (VarMisuse and QM9) depends on TensorFlow 1.13.

Hardware

In general, all experiments can run on either GPU or CPU.
