python中biu邻接矩阵的列数

Question

我想从数据帧创建一个biu邻接矩阵。我编写了以下代码：

import pandas as pd
from sklearn.model_selection import train_test_split
import networkx as nx
from operator import itemgetter
from networkx.algorithms.bipartite import biadjacency_matrix


# create the biadjacency matrix, creating a graph with data's edges
def to_adjacency_matrix(data):
    g = nx.DiGraph()
    g.add_edges_from(data)
    partition_0 = set(map(itemgetter(0), data))
    partition_1 = set(map(itemgetter(1), data))
    return biadjacency_matrix(g, partition_0).toarray(), partition_0, partition_1


df = pd.read_csv("final.csv", sep=" ", header=1, names=["Tags", "Users"])

#train dataset 90% & test dataset 10%!!!
train, test = train_test_split(df, test_size=0.1)

# change columns order to have users first
train = train[['Users', 'Tags']]
test = test[['Users', 'Tags']]

data = list(zip(*[train[c].values.tolist() for c in train]))

bi_adjacency, user_node, tag_node = to_adjacency_matrix(data)
print(bi_adjacency.shape)
print(len(user_node))
print(len(tag_node))

虽然我的unique users是41576，unique tags是10000，但我的结果是一个shape数组（415766879）。 我不明白为什么最后一个不同于（4157610000）。 有人能帮我吗

谢谢你所做的一切
