py连接Redis报错：'tuple' object has no attribute 'StrictRedis'

如题，代码中使用redis模块连接Redis报错：
 

2019-08-01 13:48:03,683 - main_check.py[line:1383] - INFO: Redis-6383 开始采集redis信息
2019-08-01 13:48:03,694 - main_check.py[line:1383] - INFO: Redis-6384 开始采集redis信息

2019-08-01 13:48:03,701 - main_check.py[line:1201] - INFO: Redis-6383：初始化redis表

连接Redis处的代码如图：

 try:
        conn = Rds.StrictRedis(host=host, port=port)
        info = conn.info()
    except Exception, e:
        error_msg = "%s redis连接失败：%s" % (tags, unicode(str(e), errors='ignore'))

但这段代码在Windows下运行时是正常的，而且单独运行也没问题：
