面向开发者的LLM入门课程-基于文档的问答英文版提示：

英文版提示

1.直接使用向量储存查询

from langchain.document_loaders import CSVLoader
from langchain.indexes import VectorstoreIndexCreator

file = ‘../data/OutdoorClothingCatalog_1000.csv’
loader = CSVLoader(file_path=file)

index =
VectorstoreIndexCreator(vectorstore_cls=DocArrayInMemorySearch).from_loaders([loa
der])

query =”Please list all your shirts with sun protection
in a table in markdown and summarize each one.”

response = index.query(query)

display(Markdown(response))

All four shirts provide UPF 50+ sun protection, blocking 98% of the sun’s harmful rays. The Men’s Tropical Plaid Short-Sleeve Shirt is made of 100% polyester and is wrinkle-resistant

2.结合表征模型和向量存储

from langchain.document_loaders import CSVLoader
from langchain.embeddings import OpenAIEmbeddings
from langchain.vectorstores import DocArrayInMemorySearch

embeddings = OpenAIEmbeddings()
embed = embeddings.embed_query(“Hi my name is Harrison”)

print(“n�33[32m向量表征的长度: �33[0m n”, len(embed))
print(“n�33[32m向量表征前5个元素: �33[0m n”, embed[:5])

file = ‘../data/OutdoorClothingCatalog_1000.csv’
loader = CSVLoader(file_path=file)
docs = loader.load()
embeddings = OpenAIEmbeddings()
db = DocArrayInMemorySearch.from_documents(docs, embeddings)

query = “Please suggest a shirt with sunblocking”
docs = db.similarity_search(query)
print(“n�33[32m返回文档的个数: �33[0m n”, len(docs))
print(“n�33[32m第一个文档: �33[0m n”, docs[0])

# 使用查询结果构造提示来回答问题
llm = ChatOpenAI(model_name=”gpt-3.5-turbo-0301″,temperature = 0.0)

qdocs = “”.join([docs[i].page_content for i in range(len(docs))])

response = llm.call_as_llm(f”{qdocs} Question: Please list all your
shirts with sun protection in a table in markdown and summarize each one.”)

print(“n�33[32m使用查询结果构造提示来回答问题: �33[0m n”, docs[0])
display(Markdown(response))

# 使用检索问答链来回答问题
retriever = db.as_retriever()

qa_stuff = RetrievalQA.from_chain_type(
llm=llm,
chain_type=”stuff”,
retriever=retriever,
verbose=True
)

query = “Please list all your shirts with sun protection in a table
in markdown and summarize each one.”

response = qa_stuff.run(query)

print(“n�33[32m 使用检索问答链来回答问题： �33[0m n”)
display(Markdown(response))
