我想将一个> 1mn记录的

MySQL数据库转换成一个图形数据库,因为它是一个链接很多的网络类型数据. Neo4J的免费版本有一些我认为可能会遇到的限制,因此我安装了OrientDB(Community 2.2.0)(在Ubuntu Server 16.04上)并使其正常运行.现在我需要从

Python(3.5.1)访问它,所以我正在尝试pyorient(1.5.2). (我尝试使用TinkerPop,因为我最终想要使用Gremlin,并且无法让gremlin控制台与OrientDB交谈.)

以下简单的Python代码,用于连接到OrientDB中的一个测试图：

import pyorient

username="user"

password="password"

client = pyorient.OrientDB("localhost", 2424)

session_id = client.connect( username, password )

print("SessionID=",session_id)

db_name="GratefulDeadConcerts"

if client.db_exists( db_name, pyorient.STORAGE_TYPE_MEMORY ):

print("Database",db_name,"exists")

client.db_open( db_name, username, password )

else:

print("Database",db_name,"doesn't exist")

给出了一个奇怪的错误：

SessionID= 27

Database GratefulDeadConcerts exists

Traceback (most recent call last):

有谁知道这是什么或如何解决它？我应该真的使用TinkerPop吗？如果是这样的话,我会发布一个关于我与之斗争的单独问题.
