python导入模块超时

我正在尝试使用netmiko(基于paramiko的ssh会话管理器)构建一个函数,并将其作为模块导入。这里是我要导入的功能:

import sys, socket, getpass
from netmiko import ConnectHandler


def sshHost(hostname):
    username = raw_input("Username: ")
    password = getpass.getpass()
    hostIp = socket.gethostbyname(hostname)
    sshSession = ConnectHandler(device_type = 'juniper', ip = hostIp, username = username, password = password)
    versionHostname = sshSession.send_command("show version | match Hostname:")
    print "Session established with ",versionHostname.strip(), "IP: ", hostIp
    return sshSession

所以,如果我运行sshHost(sys.argv[1]),该功能会按预期工作 但是,当我将其作为外部模块导入时,脚本会超时

#!/usr/bin/env python
import sys
from netmiko import ConnectHandler
from sshHostModuleJUNOS import sshHost

def showVersion(host):
    out = host.send_command("show version")
    print out

showVersion(sshHost(sys.argv[1]))

我很确定使用sshHost模块的方式有问题,但我无法弄清楚是什么

错误paramiko.ssh_exception.SSHException: No existing session
