Steps to Construct a RQA System with DeepSeek R1

Let’s construct a Retrieval Query Answering System with LangChain, powered by DeepSeek-R1 for reasoning! 

Step 1: Import Obligatory Libraries

Import needed libraries, together with streamlit, langchain_community.

import streamlit as st
from langchain_community.document_loaders.csv_loader import CSVLoader
from langchain_community.embeddings import HuggingFaceEmbeddings
from langchain_community.vectorstores import FAISS
from langchain_community.llms import Ollama
from langchain.prompts import PromptTemplate
from langchain.chains import LLMChain
from langchain.chains.combine_documents.stuff import create_stuff_documents_chain
from langchain.chains import RetrievalQA

Step 2: Streamlit File Uploader

Create a streamlit file uploader to permit CSV information to be uploaded.

# Streamlit file uploader for CSV information
uploaded_file = st.file_uploader("Add a CSV file", sort="csv")

if uploaded_file:
    # Save CSV briefly
    temp_file_path = "temp.csv"
    with open(temp_file_path, "wb") as f:
        f.write(uploaded_file.getvalue())

Step 3: Load CSV and Create Embeddings

As soon as CSV information are uploaded, load them to create embeddings. Embeddings are created utilizing HuggingFaceEmbeddings to transform the CSV information into vector representations.

loader = CSVLoader(file_path=temp_file_path)
docs = loader.load()
embeddings = HuggingFaceEmbeddings()

Step 4: Create Vector Retailer

Create a FAISS vector retailer from the paperwork and embeddings to allow environment friendly similarity search.

vector_store = FAISS.from_documents(docs, embeddings)

    2. If not sure, say "I don’t know".
    3. Maintain solutions beneath 4 sentences.

    Context: {context}

    Query: {query}

    Reply:
    """
    QA_CHAIN_PROMPT = PromptTemplate.from_template(immediate)

Step 8: Outline the QA Chain

Use the StuffDocumentsChain to mix the LLM and the immediate template right into a single chain for document-based query answering.

llm_chain = LLMChain(llm=llm, immediate=QA_CHAIN_PROMPT)
    
    # Mix doc chunks
    document_chain = create_stuff_documents_chain(
        llm=llm,
        immediate=QA_CHAIN_PROMPT
    )

Step 9: Create the RetrievalQA Chain

Initialize the RetrievalQA chain, which integrates the retriever and the LLM to reply person queries based mostly on related doc chunks.

 qa = RetrievalQA.from_chain_type(
        llm=llm,
        retriever=retriever,
        chain_type="stuff", 
    )

Step 10: Create Streamlit UI for the applying

Arrange a Streamlit textual content enter discipline the place customers can enter queries, course of the enter utilizing the RetrievalQA chain, and show the generated response.

user_input = st.text_input("Ask your CSV a query:")

    if user_input:
        with st.spinner("Pondering..."):
            attempt:
                response = qa.run(user_input)  
                st.write(response)
            besides Exception as e:
                st.error(f"Error: {str(e)}")

Save the python file (.py) and run it regionally utilizing the next command to view the UI.

#In terminal
streamlit run filename.py

Be aware: Guarantee the required libraries are put in in your system. You are able to do so by the next command. 

pip set up streamlit langchain_community transformers faiss-cpu langchain
