torch_geometric.datasets.Reddit2

class Reddit2(root: str, transform: Optional[Callable] = None, pre_transform: Optional[Callable] = None, force_reload: bool = False)[source]

Bases: InMemoryDataset

来自“GraphSAINT: 基于图采样的归纳学习方法”论文的Reddit数据集，包含属于不同社区的Reddit帖子。

注意

这是原始Reddit数据集的稀疏版本（约2300万条边，而不是约1.14亿条边），并在诸如SGC和GraphSAINT等论文中使用。

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)
