检查安装并配置Ansible Python API插件，确保正确导入Ansible模块和正确设置Ansible API插件路径。以下是可能有用的示例代码：

import ansible
from ansible.parsing.dataloader import DataLoader
from ansible.vars import VariableManager
from ansible.inventory import Inventory
from ansible.plugins.loader import CwdLoader
from ansible.playbook.play import Play
from ansible.executor.playbook_executor import PlaybookExecutor

# 配置数据加载器、变量管理器和清单
loader = DataLoader()
variable_manager = VariableManager()
inventory = Inventory(loader=loader, variable_manager=variable_manager, host_list=['localhost'])

# 配置API插件路径
plugin_path = '/usr/share/my_ansible_plugins'
variable_manager.set_inventory(inventory)
variable_manager.set_playbook_basedir(plugin_path)

# 从API插件路径加载自定义模块
CwdLoader().add_directory(plugin_path)

# 构建Play对象和PlaybookExecutor对象
play_source = dict(name='My Ansible Playbook', hosts='localhost', gather_facts='no',
    tasks=[
        dict(action=dict(module='debug', args=dict(msg='Hello world!')))
    ])
play = Play().load(play_source, variable_manager=variable_manager, loader=loader)
playbook = PlaybookExecutor(playbooks=[plugin_path+'/my_playbook.yml'], inventory=inventory,
    variable_manager=variable_manager, loader=loader, passwords={})
playbook.run()
