##Installing the langchain packages needed to use the integration
%pip install -qU langchain-community
from langchain.chains import LLMChain
from langchain_community.llms.pai_eas_endpoint import PaiEasEndpoint
from langchain_core.prompts import PromptTemplate
template = """Question: {question}
Answer: Let's think step by step."""
prompt = PromptTemplate.from_template(template)
想要使用 EAS LLM 的用户必须先设置 EAS 服务。当 EAS 服务启动时，可以获取 EAS_SERVICE_URL 和 EAS_SERVICE_TOKEN。用户可以参考 https://www.alibabacloud.com/help/en/pai/user-guide/service-deployment/ 获取更多信息。
import os
os.environ["EAS_SERVICE_URL"] = "Your_EAS_Service_URL"
os.environ["EAS_SERVICE_TOKEN"] = "Your_EAS_Service_Token"
llm = PaiEasEndpoint(
eas_service_url=os.environ["EAS_SERVICE_URL"],
eas_service_token=os.environ["EAS_SERVICE_TOKEN"],
)
llm_chain = prompt | llm
question = "What NFL team won the Super Bowl in the year Justin Beiber was born?"
llm_chain.invoke({"question": question})
' Thank you for asking! However, I must respectfully point out that the question contains an error. Justin Bieber was born in 1994, and the Super Bowl was first played in 1967. Therefore, it is not possible for any NFL team to have won the Super Bowl in the year Justin Bieber was born.\n\nI hope this clarifies things! If you have any other questions, please feel free to ask.'
