2025年Python技术前沿:AI Agent开发实战指南
AI Agent开发的核心技术栈
1. LangChain 3.0框架
LangChain 3.0是当前最流行的AI Agent开发框架,提供了完整的工具链支持:
pythonCopy Codefrom langchain3.0 import Agent, Tool
# 定义工具
def calculator(operation: str, numbers: list) -> float:
"""执行数学计算"""
return eval(operation)
# 创建Agent
agent = Agent(
tools=[Tool(name="calculator", func=calculator)],
llm="gpt-4o",
memory="vectorstore"
)
2. AutoGPT 2025应用
AutoGPT 2025实现了完全自主的AI Agent开发范式:
pythonCopy Codefrom autogpt2025 import AutoGPT
# 配置AutoGPT
ag = AutoGPT(
name="Financial Analyst",
description="分析股票市场数据并提供投资建议",
skills=["数据分析", "趋势预测", "风险评估"]
)
# 启动Agent
ag.run()
实战案例:构建智能数据分析Agent
1. 项目架构设计
一个完整的数据分析Agent通常包含以下模块:
- 数据获取层
- 数据处理引擎
- 分析模型
- 可视化界面
- 决策逻辑
2. 核心代码实现
pythonCopy Codefrom langchain3.0 import Agent
from autogpt2025 import AutoGPT
import pandas as pd
import matplotlib.pyplot as plt
class DataAnalysisAgent:
def __init__(self):
self.tools = [
Tool(name="fetch_data", func=self.fetch_data),
Tool(name="clean_data", func=self.clean_data),
Tool(name="analyze", func=self.analyze),
Tool(name="visualize", func=self.visualize)
]
def fetch_data(self, source: str) -> pd.DataFrame:
"""从指定数据源获取数据"""
# 实现数据获取逻辑
pass
def clean_data(self, df: pd.DataFrame) -> pd.DataFrame:
"""数据清洗"""
# 实现清洗逻辑
pass
def analyze(self, df: pd.DataFrame) -> dict:
"""数据分析"""
# 实现分析逻辑
pass
def visualize(self, data: dict) -> None:
"""数据可视化"""
# 实现可视化逻辑
pass
# 创建Agent实例
agent = Agent
