Tested on pytorch 1.6.0 and pytorch_geometric 1.6.1

Experiments reported on the paper are conducted in 2019 with pytorch_geometric==1.3.1. Note that the code regarding of QM9 dataset in pytorch_geometric has been changed since then. Thus, if you run this repo with pytorch_geometric>=1.6.1, you may obtain results differ from those reported on the paper.

Code regarding mutual information maximization is partially referenced from: https://github.com/rdevon/DIM
