异步 Agent 与工具

代码

cookbook/models/vllm/async_tool_use.py

"""Run `pip install duckduckgo-search` to install dependencies."""

import asyncio

from agno.agent import Agent
from agno.models.vllm import vLLM
from agno.tools.duckduckgo import DuckDuckGoTools

agent = Agent(
    model=vLLM(id="Qwen/Qwen2.5-7B-Instruct", top_k=20, enable_thinking=False),
    tools=[DuckDuckGoTools()],
    show_tool_calls=True,
    markdown=True,
)
asyncio.run(agent.aprint_response("Whats happening in France?", stream=True))

用法

1. 创建虚拟环境

   打开 Terminal 并创建一个 python 虚拟环境。

   Mac

   python3 -m venv .venv
   source .venv/bin/activate
   
2. 安装库

   pip install -U agno openai vllm duckduckgo-search
   
3. 启动 vLLM 服务器

   vllm serve Qwen/Qwen2.5-7B-Instruct \
       --enable-auto-tool-choice \
       --tool-call-parser hermes \
       --dtype float16 \
       --max-model-len 8192 \
       --gpu-memory-utilization 0.9
   
4. 运行 Agent

   python cookbook/models/vllm/async_tool_use.py
