在下面代码
https://github.com/jm199504/Financial-Knowledge-Graphs/blob/master/code/python_to_neo4j.ipynb

的这一步，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]))

报以下错误
File "E:\Anaconda3\lib\site-packages\py2neo\data.py", line 847, in init
Entity.init(self, (n[0], self, n[1]), properties)
File "E:\Anaconda3\lib\site-packages\py2neo\data.py", line 553, in init

_ = node.labels # ensure not stale
AttributeError: 'NoneType' object has no attribute 'labels'

Process finished with exit code 1

是哪儿设置错误了吗？
