AttributeError: тип объекта «ManagerWithFind» не имеет атрибут «клиент»

Question

Я новичок в Python и OpenStack поэтому, пожалуйста, не теряйте круто :)

Здесь я пытаюсь создать экземпляр BareMetalNodeManager объект класса (от np_orchestration. ру).

np_orchestration.py

from baremetal import BareMetalNodeManager 
from novaclient import base 

class np_orchestration: 
    def provisionNodes(self): 
     obj = BareMetalNodeManager(base.ManagerWithFind); 
     var =  obj.create(self,"192.168.XXX.XXX",1,514,1,"00:0C:29:XX:XX:XX","192.168.XXX.XXX","XXXX","XXXX") 
     print var 

obj = np_orchestration() 
obj.provisionNodes() 

Этот класс (расположен в baremetal.py) требует base.ManagerWithFind в качестве параметра (который является абстрактным классом)

baremetal.py

class BareMetalNodeManager(base.ManagerWithFind): 
""" 
Manage :class:`BareMetalNode` resources. 
""" 
resource_class = BareMetalNode 

def create(self, 
      service_host, 
      cpus, 
      memory_mb, 
      local_gb, 
      prov_mac_address, 
      pm_address=None, 
      pm_user=None, 
      pm_password=None, 
      terminal_port=None): 
    """ 
    Create a baremetal node. 

    :param service_host: Name of controlling compute host 
    :param cpus: Number of CPUs in the node 
    :param memory_mb: Megabytes of RAM in the node 
    :param local_gb: Gigabytes of local storage in the node 
    :param pm_address: Power management IP for the node 
    :param pm_user: Username for the node's power management 
    :param pm_password: Password for the node's power management 
    :param prov_mac_address: MAC address to provision the node 
    :param terminal_port: ShellInABox port 
    :rtype: :class:`BareMetalNode` 
    """ 
    body = {'node': {'service_host': service_host, 
        'cpus': cpus, 
        'memory_mb': memory_mb, 
        'local_gb': local_gb, 
        'pm_address': pm_address, 
        'pm_user': pm_user, 
        'pm_password': pm_password, 
        'prov_mac_address': prov_mac_address, 
        'terminal_port': terminal_port}} 

    return self._create('/os-baremetal-nodes', body, 'node') 

При попытке сделать следующее:
