可以看到,add_self_loops 会在原先的edge_index 的后面添加 0->0 , 1->1 , 2->2 的连接 3.4.2 knn 在torch_geometric 的依赖库 torch_cluster 当中,已经实现了 knn 算法,如下图,我进行了如下操作: 随机生成了5个点的坐标 利用knn算法,找到了这些点之间的关系 根据pos 和 edge_index 构建 data 以上...

📚 Installation I want to have a taste of pytorch_geometric, so I installed the CPU-only version. No errors appeared while pip install. I encountered the FileNotFoundError while from torch_geometric.data import Data. I ensured that the .p...
