I wrote the following python code to neo4j using py2neo
from py2neo import Graph
from py2neo import neo4j,Node,Relationship
sgraph = Graph()
alice = Node("person",name="alice")
bob = Node("person",name="bob")
alice_knows_bob = Relationship(alice,"KNOWS",bob)
sgraph.create(alice_knows_bob)
but i got the following error
