Amadeus 工具包

此笔记本将引导您将 LangChain 连接到Amadeus 旅行 API。

此Amadeus 工具包允许代理在旅行方面做出决策，尤其是在搜索和预订包含航班的行程方面。

要使用此工具包，您需要准备好 Amadeus API 密钥，在Amadeus 自助服务 API 入门指南中进行了说明。收到 AMADEUS_CLIENT_ID 和 AMADEUS_CLIENT_SECRET 后，您可以将它们作为环境变量输入到下方。

注意：Amadeus 自助服务 API 提供了一个带有免费有限数据的测试环境。这允许开发人员在将其应用程序部署到生产环境之前构建和测试其应用程序。要访问实时数据，您需要迁移到生产环境。

%pip install --upgrade --quiet  amadeus > /dev/null

%pip install -qU langchain-community

分配环境变量

该工具包将读取 AMADEUS_CLIENT_ID 和 AMADEUS_CLIENT_SECRET 环境变量以对用户进行身份验证，因此您需要在此处设置它们。

# Set environmental variables here
import os

os.environ["AMADEUS_CLIENT_ID"] = "CLIENT_ID"
os.environ["AMADEUS_CLIENT_SECRET"] = "CLIENT_SECRET"

# os.environ["AMADEUS_HOSTNAME"] = "production" or "test"

创建 Amadeus 工具包并获取工具

首先，您需要创建工具包，以便以后可以访问其工具。

默认情况下，AmadeusToolkit 使用 ChatOpenAI 来识别离给定位置最近的机场。要使用它，只需设置 OPENAI_API_KEY。

os.environ["OPENAI_API_KEY"] = "YOUR_OPENAI_API_KEY"

from langchain_community.agent_toolkits.amadeus.toolkit import AmadeusToolkit

toolkit = AmadeusToolkit()
tools = toolkit.get_tools()

API 参考：AmadeusToolkit

或者，您可以使用 langchain 支持的任何 LLM，例如 HuggingFaceHub。

from langchain_community.llms import HuggingFaceHub

os.environ["HUGGINGFACEHUB_API_TOKEN"] = "YOUR_HF_API_TOKEN"

llm = HuggingFaceHub(
    repo_id="tiiuae/falcon-7b-instruct",
    model_kwargs={"temperature": 0.5, "max_length": 64},
)

toolkit_hf = AmadeusToolkit(llm=llm)

API 参考：HuggingFaceHub

在代理中使用 Amadeus 工具包

from langchain import hub
from langchain.agents import AgentExecutor, create_react_agent
from langchain.agents.output_parsers import ReActJsonSingleInputOutputParser
from langchain.tools.render import render_text_description_and_args
from langchain_openai import ChatOpenAI

API 参考：AgentExecutor | create_react_agent | ReActJsonSingleInputOutputParser | render_text_description_and_args | ChatOpenAI

llm = ChatOpenAI(temperature=0)

prompt = hub.pull("hwchase17/react-json")
agent = create_react_agent(
    llm,
    tools,
    prompt,
    tools_renderer=render_text_description_and_args,
    output_parser=ReActJsonSingleInputOutputParser(),
)

agent_executor = AgentExecutor(
    agent=agent,
    tools=tools,
    verbose=True,
)
