[Python] Correctly using banner_timeout in paramiko

I'm trying to have many clients send files to a server all at once (or as fast as possible) but the server is getting too many requests at once as in the question Paramiko: Error reading SSH protocol banner. I've tried adding a banner_timeout so that the clients will try a little longer to connect to server, however, I get an error:

TypeError: connect() got an unexpected keyword argument 'banner_timeout'

import paramiko, os, time
host_IP='192.168.1.1'
port=22
transport=paramiko.Transport((host_IP,port))
transport.connect(username='username', password='password', banner_timeout=60)
sftp=paramiko.SFTPClient.from_transport(transport)


Perhaps I'm using the transport incorrectly?
