由于torch_geometric.GCNCov内部可以不使用完整的邻接矩阵(即整个图结构)来执行卷积操作,而是输入边的集合来进行卷积,而不是以矩阵的形式进行卷积:D^(-0.5)AD^(-0.5)W,具体可参考论文SEMI-SUPERVISED CLASSIFICATION WITHGRAPH CONVOLUTIONAL NETWORKS。记边的集合为edge_index,edge_index.shape=[2,E], E是边的数量。

你好!我是Comate,很高兴能帮助你解答关于torch_geometric.nn模块中GCNConv类的导入问题。 模块和类名分析: 你尝试从torch_geometric.nn模块中导入一个名为gcnconv的类。 模块名检查: torch_geometric.nn是torch_geometric库中的一个子模块,专门用于图神经网络(Graph Neural Networks, GNNs)的层构建。这个模块名是...
