最近使用python3.4 的cx_Oracle 模块连接oracle数据库报错UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 82-83: invalid continuation byte 但是我换成python2.7 就正常运行，并且查询出了需要的数据，哪位同学遇到过这种问题呢，跪求啊，下面是我的代码和报错信息：

import cx_Oracle

conn = cx_Oracle.connect('tdqesure','ife04','10.183.146.5:1521/ydsl')
cursor = conn.cursor()
cursor.execute("select * from pdd")

报错信息：
Traceback (most recent call last):
File "E:/pycharmSpace/taikang/oracle.py", line 3, in 
conn = cx_Oracle.connect('tkinsure','ins185','10.137.146.5:1521/ursl')
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 82-83: invalid continuation byte
