class DeezerEurope(root: str, transform: Optional[Callable] = None, pre_transform: Optional[Callable] = None, force_reload: bool = False)[source]

Bases: InMemoryDataset

在“图上的特征函数：同类相吸，从统计描述符到参数模型”论文中介绍的Deezer欧洲数据集。 节点代表Deezer的欧洲用户，边是相互关注的关系。 它包含28,281个节点，185,504条边，128个节点特征和2个类别。

Parameters:

  • root (str) – Root directory where the dataset should be saved.

  • transform (callable, optional) – A function/transform that takes in an torch_geometric.data.Data object and returns a transformed version. The data object will be transformed before every access. (default: None)

  • pre_transform (callable, optional) – A function/transform that takes in an torch_geometric.data.Data object and returns a transformed version. The data object will be transformed before being saved to disk. (default: None)

  • force_reload (bool, optional) – Whether to re-process the dataset. (default: False)
