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 codebase with pytorch_geometric>=1.6.1, you may obtain results different from those reported on the paper.
