Question

python代码错误求助！！！

from matplotlib.pyplot import plot
from networkx import Graph
def community_label_propagation(self, weights=None, initial=None, fixed=None):
if isinstance(fixed, basestring):
fixed = [bool(o) for o in g.vs[fixed]]
cl = GraphBase.community_label_propagation(self, weights, initial, fixed)
return VertexClustering(self, cl, modularity_params=dict(weights=weights))
f = open('yourtest.txt','r')
test = {}
for i in f.readlines()[1:]:
people,friends = i.split()[0],i.split()[1:] #根据自己数据集去索引相应内容
test.setdefault(people,friends)

g = Graph()
for i in test.keys():
g.add_node(str(i))
edges = []
for i in test.keys():
for j in test[i]:
edges.append((str(i),str(j)))

#去重
new = []
for i in edges:
new.append(tuple(sorted(list(i))))

g.add_edge(set(new))
print(g.community_label_propagation())

plot(g)

报错是：TypeError: add_edge() missing 1 required positional argument: 'v_of_edge'
求助各位大神ballball大家！！

Answer 1

由于牵涉到具体业务数据，提供参考如下：

由报错提示看 add_edge() missing 1 required positional argument: 'v_of_edge' 判断，可能是由于调用参数错误。

add_edge 的函数原型及说明如下：

add_edge()函数，该函数在调用时需要传入两个参数：u 和 v，以及其它多个可选参数。
