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, Graph

In [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&nbsp;=&nbsp;Graph('graph',&nbsp;'r')应该 ：g&nbsp;=&nbsp;Graph('graph',&nbsp;r)
