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

Bases: InMemoryDataset

来自“Wiki-CS: A Wikipedia-Based Benchmark for Graph Neural Networks”论文的半监督基于维基百科的数据集，包含11,701个节点，216,123条边，10个类别和20个不同的训练分割。

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)

  • is_undirected (bool, optional) – 图是否为无向图。 (默认值: True)

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