Environment and Packages

  • python 3.9
  • cuda 11.1
  • pytorch 1.9.1+cu111
  • torhcvision 0.10.1+cu111
  • torchaudio 0.9.1
  • pytorch_geometric
  • torch-sparse
  • torch-geometric
  • pytorch-lightning 1.7.7

if error (module 'distutils'), please install setuptools 59.5.0

requirement.txt is also provided for reference, but compatibility still depends on the devices.

pytorch-lightning version incompatibility may cause extremely long training time and degraded result. (millions of thanks for colleagues asking questions related to this problem by emailing and in issues)

Usage
