创建关系的时候报错AttributeError: 'NoneType' object has no attribute 'labels'

[mf093087]

在这一步，报错。
matcher = NodeMatcher(graph)
for i in holder.values:
a = matcher.match("股票",TS代码=i[0]).first()
b = matcher.match("股东",TS代码=i[0])
for j in b:
r = Relationship(j,'参股',a)
graph.create(r)
print('TS',str(i[0]))

graph.create(Relationship(j,'参股',a))

我是把代码改成了
for i in stock.values:
a = matcher.match("股票" ,TS代码=i[1]).first()
b = matcher.match("股东" ,TS代码=i[1])
for j in b:
r = Relationship(j ,'参股' ,a)
graph.create(r)
print("TS代码为" + i[1] + "的股票与股东的关系建立成功")
主要是1）在stock_holders.csv里面，TS代码在第二列也就是i[1]
2）如果遍历holder的话要跑16万（i的个数，stock_holders.csv的条目数）*16万（j的个数，股东实体的个数）次，慢的要死；遍历stock是一样的，但是只用跑4千（i的个数，stock_basic.csv的条目数）*16万次
