初识camel智能体（一）

同目录下配置环境变量.env，内容如下，

apikey从魔搭社区获取

QWEN_API_KEY=4ff3ac8f-aebc********

先上干货代码，主代码如下：

from colorama import Forefrom camel.societies import RolePlaying
from camel.utils import print_text_animated
from camel.models import ModelFactory
from camel.types import ModelPlatformTypefrom dotenv import load_dotenvimport osload_dotenv(dotenv_path='.env')api_key = os.getenv('QWEN_API_KEY')model = ModelFactory.create(model_platform=ModelPlatformType.OPENAI_COMPATIBLE_MODEL,model_type="Qwen/Qwen2.5-72B-Instruct",url='https://api-inference.modelscope.cn/v1/',api_key=api_key
)def main(model=model, chat_turn_limit=50) -> None:task_prompt = "为股票市场开发一个交易机器人"#设置任务目标role_play_session = RolePlaying(assistant_role_name="Python 程序员",#设置AI助手角色名assistant_agent_kwargs=dict(model=model),user_role_name="股票交易员",#设置用户角色名，在roleplay中，user用于指导AI助手完成任务user_agent_kwargs=dict(model=model),task_prompt=task_prompt,with_task_specify=True,task_specify_agent_kwargs=dict(model=model),output_language='中文'#设置输出语言)print(Fore.GREEN+ f"AI 助手系统消息:\n{role_play_session.assistant_sys_msg}\n")print(Fore.BLUE + f"AI 用户系统消息:\n{role_play_session.user_sys_msg}\n")print(Fore.YELLOW + f"原始任务提示:\n{task_prompt}\n")print(Fore.CYAN+ "指定的任务提示:"+ f"\n{role_play_session.specified_task_prompt}\n")print(Fore.RED + f"最终任务提示:\n{role_play_session.task_prompt}\n")n = 0input_msg = role_play_session.init_chat()while n < chat_turn_limit:n += 1assistant_response, user_response = role_play_session.step(input_msg)if assistant_response.terminated:print(Fore.GREEN+ ("AI 助手已终止。原因: "f"{assistant_response.info['termination_reasons']}."))breakif user_response.terminated:print(Fore.GREEN+ ("AI 用户已终止。"f"原因: {user_response.info['termination_reasons']}."))breakprint_text_animated(Fore.BLUE + f"AI 用户:\n\n{user_response.msg.content}\n")print_text_animated(Fore.GREEN + "AI 助手:\n\n"f"{assistant_response.msg.content}\n")if "CAMEL_TASK_DONE" in user_response.msg.content:breakinput_msg = assistant_response.msgif __name__ == "__main__":main()

运行结果如下 ：
