WebWith this, we are ready to initialize our HeteroData object and pass two node types into it: from torch_geometric.data import HeteroData data = HeteroData() data['user'].num_nodes = len(user_mapping) # Users do not have any features. data['movie'].x = movie_x print(data) HeteroData( user={ num_nodes=610 }, movie={ x[9742, 404] } ) Webtorch.utils.data.Dataset is an abstract class representing a dataset. Your custom dataset should inherit Dataset and override the following methods: __len__ so that len (dataset) returns the size of the dataset. __getitem__ to support the indexing such that dataset [i] can be used to get i i th sample.
