Web9 jul. 2024 · @tom Hi，Thomas. Thanks for your time. I‘ve fixed the problems with following your proposal. Webing on homogeneous graphs, i.e., graphs with just one type of rela-tion. Examples include DeepWalk [27] and node2vec [12]. These approaches are based on random walks for embedding generation. For each node in the graph, these models generate a random path of connected nodes. The random path gives a sequence of nodes, crystal rocks for healingWeb如果加载的DGLgraph为异构图，则执行异构图转同构图的操作(使用dgl.metapath_reachable_graph方法对异构图进行提取操作，提取对象为给定元路径到达的节点，比如"pa-ap"即为经author节点连接的paper节点；使用dgl.to_homogeneous方法将提取节点后的异构图进行向同构图的转换) ... dying light unfinished story
