错误的异常栈为：

File "/usr/local/python27/lib/python2.7/site-packages/py2neo/cypher/core.py", line 136, in execute    results = tx.commit()  File "/usr/local/python27/lib/python2.7/site-packages/py2neo/cypher/core.py", line 333, in commit    return self.post(self.__commit or self.__begin_commit)  File "/usr/local/python27/lib/python2.7/site-packages/py2neo/cypher/core.py", line 275, in post    rs = resource.post({"statements": self.statements})  File "/usr/local/python27/lib/python2.7/site-packages/py2neo/core.py", line 307, in post    response = self.__base.post(body, headers, **kwargs)  File "/usr/local/python27/lib/python2.7/site-packages/py2neo/packages/httpstream/http.py", line 984, in post    return rq.submit(**kwargs)  File "/usr/local/python27/lib/python2.7/site-packages/py2neo/packages/httpstream/http.py", line 433, in submit    http, rs = submit(self.method, uri, self.body, self.headers)  File "/usr/local/python27/lib/python2.7/site-packages/py2neo/packages/httpstream/http.py", line 362, in submit    raise SocketError(code, description, host_port=uri.host_port)py2neo.packages.httpstream.http.SocketError: timed out

显然这是http链接发生超时，可能的原因是查图库时查询速度过慢一直没有响应。解决方法为，设置超时时间。引入：

from py2neo.packages.httpstream import httphttp.socket_timeout = 9999
