搭建 GCN 的方式与搭建其他 Keras 模型没有任何区别，只是需要注意 GraphConv 层的输入为 X 与 A： X_in = Input (shape= (F, )) A_in = Input ( (N, ), sparse=*True*) X_1 = GraphConv (16, 'relu') ( [X_in, A_in]) X_1 = Dropout (0.5) (X_1) X_2 = GraphConv (n_classes, 'softmax') ( [X_1, A_in]) model = Model (inputs= [X_in, A_in], outputs=X_2) 至此，我们已经完成了 GCN 的搭建，是不是非常简 …

The core of the GCN neural network model is a “graph convolution” layer. This layer is similar to a conventional dense layer, augmented by the graph adjacency matrix to use information about a node’s connections. This algorithm is discussed in more detail in “Knowing Your Neighbours: Machine Learning on Graphs”.
