This repository is the official PyTorch implementation of "KerGNNs: Interpretable Graph Neural Networks with Graph Kernels", Aosong Feng, Chenyu You, Shiqiang Wang, Leandros Tassiulas, AAAI 2022 [link] (https://arxiv.org/abs/2201.00491).

Install PyTorch following the instuctions on the [official website] (https://pytorch.org/). The code has been tested over PyTorch 1.6.0 version.

Then install the other dependencies.

pip install -r requirements.txt

All the dataset are downloaded from
