Dataset Download Fail

[dongzizhu]

Hi, thanks for sharing the great work!

I'm trying to run the code for unsupervised TU with NCI1, and the data download has failed.

Could you please share the dataset?

@dongzizhu Thanks for pointing out the obsolete links to the datasets!

@yyou1996 Could you please revise the links in the source code for the TU data download? The latest seems to be at https://www.chrsmrrs.com/graphkerneldatasets/NAME.zip

[yyou1996]

The link seems to be indeed obsoleted. https://www.chrsmrrs.com/graphkerneldatasets/NAME.zip is the latest one (replace NAME with the dataset name) according to https://pytorch-geometric.readthedocs.io/en/2.4.0/_modules/torch_geometric/datasets/tu_dataset.html#TUDataset.

Unfortunately the dataset downloading and processing function is part of the package torch_geometric that I am not able to modify in this source code. The recommended solution is to write a subclass for the torch_geometric.datasets.tu_dataset dataset class which only replaces the link.
