python连接teradata_Python teradata Uda Exec ODBC连接问题

我还在系统上创建了一个ODBC数据源,并能够使用它成功地(使用Teradata SQL Assistant)登录到Teradata系统(在不同的服务器上)。驱动程序版本为13.00.00.09

我编写了一个小测试代码,但由于ODBC连接问题而失败:

import Teradata

import pandas as pd

import sys

print("attempting TD connection")

udaExec = teradata.UdaExec(appName="just_td_test", version="1.0", logConsole=False)

#

with udaExec.connect(method="odbc",system="abc", username="aaaaa",password="xxxxx", driver="Teradata") as connect:

print("connection done. querying now...")

query = "select top 10 tablename from dbc.tables;"

df = pd.read_sql(query,connect)

print(df.head())

connect.close()

错误消息:

attempting TD connection

Traceback (most recent call last):

File "td.py", line 16, in

with udaExec.connect(method="odbc",system="abc", username="aaaaa",password="xxxxx", driver="Teradata") as connect:

很明显,ODBC连接有错误,但错误消息不清楚。Teradata ODBC驱动程序版本是13,而pypi提供了Teradata python模块版本15。这就是错误的原因吗?
