torch_geometric.datasets.Twitch

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

Bases: InMemoryDataset

Twitch Gamer网络在“多尺度属性节点嵌入”论文中介绍。节点代表Twitch上的游戏玩家，边代表他们之间的关注关系。节点特征代表Twitch用户所玩游戏的特征嵌入。任务是预测用户是否流媒体成熟内容。

Parameters:

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

  • name (str) – 数据集的名称 ("DE", "EN", "ES", "FR", "PT", "RU").

  • 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)
