Dependencies


Training

  • Citation datasets (Cora, Citeseer, and Pubmed) are automatically downloaded before training.

  • Default dataset (download) location is '/data/datasets', you may change it via args '--data-root [data_location]'.

      python train.py --data-root [data_location] --config config/Regular/FGNRegularCoraPubmed.yaml
    
  • To save your model during training

      python lifelong_data.py --data-root [data_location] --config config/Regular/FGNRegularCoraPubmed.yaml --save [model_file_location]
    
  • To try some baselined model under --model with GCN, GAT, MLP, SAGE and APP

      python lifelong_data.py --data-root [data_location] --config config/Regular/BaselineRegularCoraPubmed.yaml --save [model_file_location] --model [modle_name]
    

LifeLong Learning

  • Class-incremental Tasks

      python lifelong.py --data-root [data_location] --config config/ClassIncremental/FGNClassIncrementalCoraPubmed.yaml --save [model_file_location]
    
  • Data-incremental Tasks

      python lifelong_data.py --data-root [data_location] --config config/ --config config/DataIncremental/FGNDatalifelongCoraPubmed.yaml --save [model_file_location]
    

Testing

  • Download pretrained models. Change the path of the pretrained model under --load, and change the --config.

      python train.py --data-root [data_location] --config config/Regular/FGNRegularOGB.yaml --load pretrained_model/Regular/nonlifelongFGNKTransCat_ogbn-arxiv.pt
