이 노트북은 LangChain을 Amadeus 여행 API에 연결하는 방법을 안내합니다. 이 Amadeus toolkit은 agent가 여행과 관련된 결정을 내릴 수 있도록 하며, 특히 항공편 검색 및 예약을 지원합니다. 이 toolkit을 사용하려면 Amadeus API key가 필요하며, 자세한 내용은 Get started Amadeus Self-Service APIs에서 확인할 수 있습니다. AMADEUS_CLIENT_ID와 AMADEUS_CLIENT_SECRET를 받으면 아래와 같이 환경 변수로 입력할 수 있습니다. 참고: Amadeus Self-Service API는 무료 제한 데이터가 제공되는 테스트 환경을 제공합니다. 이를 통해 개발자는 프로덕션에 배포하기 전에 애플리케이션을 빌드하고 테스트할 수 있습니다. 실시간 데이터에 액세스하려면 프로덕션 환경으로 이동해야 합니다. 
pip install -qU  amadeus > /dev/null

pip install -qU langchain-community

​
환경 변수 할당

toolkit은 사용자를 인증하기 위해 AMADEUS_CLIENT_ID와 AMADEUS_CLIENT_SECRET 환경 변수를 읽으므로 여기에서 설정해야 합니다. 
# 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"

​
Amadeus Toolkit 생성 및 Tool 가져오기

시작하려면 toolkit을 생성하여 나중에 해당 tool에 액세스할 수 있도록 해야 합니다. 기본적으로 AmadeusToolkit은 ChatOpenAI를 사용하여 주어진 위치에서 가장 가까운 공항을 식별합니다. 이를 사용하려면 OPENAI_API_KEY를 설정하기만 하면 됩니다. 
os.environ["OPENAI_API_KEY"] = "YOUR_OPENAI_API_KEY"

from langchain_community.agent_toolkits.amadeus.toolkit import AmadeusToolkit

toolkit = AmadeusToolkit()
tools = toolkit.get_tools()
또는 HuggingFaceHub와 같이 langchain에서 지원하는 모든 LLM을 사용할 수 있습니다. 
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)

 Error: Earliest and latest departure dates need to be the  same date. If you're trying to search for round-trip  flights, call this function for the outbound flight first,  and then call again for the return flight.

We have retrieved the flight options, but we need to calculate the total travel time for each option to find the cheapest flight's full travel time.
