Question

我有一个有节点和边缘（加权）的有向图G和Im计算每个节点的in_degree_centrality（G）和out_degree_centrality（G），当我单独平均它们时我不知道为什么但是对于所有的图形平均值indegree与avg outdegree相同。我认为add_edge有问题。在我的图中，相同的2个节点之间可能存在多个边缘，其权重是csv边缘文件中该边缘的边界。

前4个图表的输出

我的节点格式（word，postag）csv文件：

What, WP
makes, VBZ
them, PRP
do, VB
it, PRP
Abject, NNP
need, NN

边缘格式（源，目标，权重）csv文件：

 WP, VBZ,2
 VBZ, PRP,2
 PRP, VB,3
 VB, PRP,3
 PRP, NNP,1
 NNP, NN,8

但如果我打印出indegree和outdegree值，它们就不相等（第一张图）
