Hi,
When I accessed to the webpage of Havard to look for dataset. I saw 2 QM9 files, including qm9_crude.msgpack.tar.gz and
qm9_featurized.msgpack.tar.gz. But none of them have the summary file.
Can you give me the link to the exact GEOM's QM9. I cannot find the archive of dataset aligned with your code.
