Thanks for your attention. As for this issue, if you want to use our repo directly, please configure the corresponding environment according to the file of environment.yaml in this repo; otherwise, you need to adapt some code in this repo if you want to use the latest version of packages like pytorch_geometric.

Hi, I configure the corresponding environment according to the file of environment.yaml in this repo. I meet some mistakes. When I directly run conda env create -f environment.yaml, there is an error:

After I change the channels in the environment.yaml, it works. But when I run from torch_geometric.data import DataLoader, there is an error:

I know how to fix the dataset loading error --> "The 'data' object was created by an older version of PyG".

You can just downgrade to torch-geometric==1.7.2 to load in the data, no reason to re-install torch-scatter, etc. Looks like @ryderling save pickle files which cannot be loaded within PyG 2.0
