Python 名称错误：名称'；a对象'；没有定义

我已与pip安装了facebook_业务：

pip install facebook_business

我相信我的凭证是正确的，因为我可以打印活动列表，id如下：

import sys
sys.path.append('C:/users/user/anaconda3/lib/site-packages') 
sys.path.append('C:/users/user/anaconda3/lib/site-packages/facebook_business-8.0.2-py3.7.egg/')

from facebook_business.api import FacebookAdsApi
from facebook_business.adobjects.adaccount import AdAccount

my_app_id = 'XXX'
my_app_secret = 'XXX'
my_access_token = 'XXX'
FacebookAdsApi.init(my_app_id, my_app_secret, my_access_token)

my_account = AdAccount('act_XXX')
campaigns = my_account.get_campaigns()
print(campaigns)

结果:

[<Campaign> {"id": "xxx"}, <Campaign> {"id": "xxx"}]

我得到这个错误：

NameError: name 'adobjects' is not defined

我是这样导入的，现在可以使用了：

from facebook_business.adobjects.abstractcrudobject import  AbstractCrudObject

您没有将“ADObject”导入模块的命名空间。谢谢，我如何导入它？

from facebook_business.adobjects.abstractcrudobject import  AbstractCrudObject
