Python AttributeError:type object'；ManagerWithFind'；没有属性'；客户'；

我是python和openstack的新手，所以请不要失去冷静：）

这里我尝试实例化BareMetalNodeManager类对象（来自np_orchestration.py）

np\u编排.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()

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):
    """

    :param service_host: Name of controlling compute host

    :rtype: :class:`BareMetalNode`
    """
    body = {'node': {'service_host': service_host,
                    'cpus': cpus,
                    'memory_mb': memory_mb,
                    'local_gb': local_gb,

                    'prov_mac_address': prov_mac_address,
                    'terminal_port': terminal_port}}

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

此类（位于baremetal.py中）需要base.ManagerWithFind作为参数（这是一个抽象类）

裸金属.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()

class BareMetalNodeManager(base.ManagerWithFind):
"""

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):

    body = {'node': {'service_host': service_host,
                    'cpus': cpus,

                    'terminal_port': terminal_port}}

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

当我尝试执行此操作时，会出现以下错误：

谢谢。作为将来的参考，最新的novaclient需要client.HTTPClient而不是_construct_http_client（），还需要将project_id=None作为projectd=None传递
