ModuleNotFoundError: No module named 'camel.agents'; 'camel' is not a package

Dear camel users,

I'm trying to run examples/ai_society/role_playing.py and I got the following error:

ModuleNotFoundError: No module named 'camel.agents'; 'camel' is not a package

Here, I customized the program by using a local model:

model = ModelFactory.create(
model_platform=ModelPlatformType.VLLM,
model_type="DeepSeek-R1-Distill-Llama-8B",
url="http://localhost:8000/v1", # 可选
model_config_dict={"temperature": 0.4}, #可选
)

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
)
...

And I'm sure I have installed camel & camel.ai package successfully:

(camel) ey8971@BJ-UNICORN-01:~/rag$ conda list | grep camel
camel 0.1.2 pypi_0 pypi
camel-ai 0.2.38 pypi_0 pypi

I'll appreciate for any suggestions for this issue.
