Amadeus Toolkit

本筆記本將引導您將 LangChain 連接到 Amadeus 旅行 API。

此 Amadeus 工具組允許代理在旅行方面做出決策，尤其是搜尋和預訂包含航班的行程。

要使用此工具組，您需要準備好您的 Amadeus API 金鑰，如 Amadeus 自助服務 API 入門中所述。收到 AMADEUS_CLIENT_ID 和 AMADEUS_CLIENT_SECRET 後，您可以將它們作為環境變數輸入如下。

注意：Amadeus 自助服務 API 提供一個測試環境，其中包含免費的有限數據。這允許開發人員在將其應用程式部署到生產環境之前建立和測試它們。要訪問即時數據，您需要遷移到生產環境。

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

%pip install -qU langchain-community

指定環境變數

該工具組將讀取 AMADEUS_CLIENT_ID 和 AMADEUS_CLIENT_SECRET 環境變數以驗證使用者身分，因此您需要在這裡設定它們。

# 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"

建立 Amadeus 工具組並取得工具

首先，您需要建立工具組，以便稍後可以訪問其工具。

預設情況下，AmadeusToolkit 使用 ChatOpenAI 來識別最靠近給定位置的機場。要使用它，只需設定 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 參考：AmadeusToolkit

或者，您可以使用 langchain 支援的任何 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 參考：HuggingFaceHub
