在图中创建节点？

Question

试图通过 python 创建一个节点，我做错了什么：In [1]: import redis   ...: from redisgraph import Node, Edge, GraphIn [2]: r = redis.Redis(host='localhost', port=6379)In [3]: g = Graph('graph', 'r')In [4]: test3 = Node(label='test3', properties={ 'abc' : 9, 'age': 33})In [5]: g.add_node(test3)In [6]: g.commit() ---------------------------------------------------------------------------AttributeError                            Traceback (most recent call last)<ipython-input-6-b6b3d9b0a206> in <module>()----> 1 g.commit()/usr/local/lib/python2.7/dist-packages/redisgraph/client.pyc in    commit(self)    134             query = query[:-1]    135 --> 136         return self.query(query)    137     138     def flush(self):/usr/local/lib/python2.7/dist-packages/redisgraph/client.pyc in  query(self, q)    153         statistics = None    154         result_set = None--> 155         response =   self.redis_con.execute_command("GRAPH.QUERY", self.name, q)    156     157         result_set = response[0]AttributeError: 'str' object has no attribute 'execute_command'发现错误：g = Graph('graph', 'r')应该 ：g = Graph('graph', r)

Answer 1

发现错误：

g = Graph('graph', 'r')

应该 ：

g = Graph('graph', r)
