Paramiko / Netmiko SSH Error - 'paramiko.buffered_pipe.PipeTimeout'

Question

netmiko script

from netmiko import ConnectHandler

    iosv_l2 = {
        'device_type': 'cisco_ios',
        'ip': '192.168.122.2',
        'username': 'test',
        'password': '123',
    }

    net_connect = ConnectHandler(**iosv_l2)
    output = net_connect.send_command('show ip int brief')
    print (output)

    config_commands = ['int loop 0', 'ip address 1.1.1.1 255.255.255.0']
    output = net_connect.send_config_set(config_commands)
    print (output)

    for n in range (2,21):
        print ("Creating VLAN " + str(n))
        config_commands = ['vlan ' + str(n), 'name Python_VLAN ' + str(n)]
        output = net_connect.send_config_set(config_commands)
        print (output)

I end up with this error

Did you configure the user privilege level? When configuring users, use username test privilege 15 password 123. If you forget to mention privilege rights you will end up with this error.
