Coding the Multi-file Chatbot

4.1 Importing Dependencies

import streamlit as st
from docx import Doc
from PyPDF2 import PdfReader
from langchain.text_splitter import CharacterTextSplitter
from langchain.embeddings import OpenAIEmbeddings, HuggingFaceInstructEmbeddings
from langchain.vectorstores import FAISS
from langchain.chat_models import ChatOpenAI
from langchain.reminiscence import ConversationBufferMemory
from langchain.chains import ConversationalRetrievalChain
from htmlTemplates import css, bot_template, user_template
from langchain.llms import HuggingFaceHub
import os
from dotenv import load_dotenv
import tempfile
from transformers import pipeline
import pandas as pd
import io

Processing the beneath information:

PDF Recordsdata

# Extract textual content from a PDF file

def get_pdf_text(pdf_file):
    textual content = ""
    pdf_reader = PdfReader(pdf_file)
    for web page in pdf_reader.pages:
        textual content += web page.extract_text()
    return textual content

Docx Recordsdata

# Extract textual content from a DOCX file

def get_word_text(docx_file):
    doc = Doc(docx_file)
    textual content = "n".be part of([paragraph.text for paragraph in document.paragraphs])
    return textual content

Txt Recordsdata

# Extract textual content from a TXT file
def read_text_file(txt_file):
    textual content = txt_file.getvalue().decode('utf-8')
    return textual content

CSV Recordsdata

Along with PDFs and DOCX information, our chatbot can work with CSV information. We use the Hugging Face Transformers library to reply questions based mostly on tabular knowledge. Right here’s how we deal with CSV information and consumer questions:

def handle_csv_file(csv_file, user_question):
    # Learn the CSV file
    csv_text = csv_file.learn().decode("utf-8")
    # Create a DataFrame from the CSV textual content
    df = pd.read_csv(io.StringIO(csv_text))
    df = df.astype(str)
    # Initialize a Hugging Face table-question-answering pipeline
    qa_pipeline = pipeline("table-question-answering", mannequin="google/tapas-large-finetuned-wtq")
    # Use the pipeline to reply the query
    response = qa_pipeline(desk=df, question=user_question)
    # Show the reply

4.3 Constructing a Information Base

The extracted textual content from completely different information is mixed and break up into manageable chunks. These chunks are then used to create an clever information base for the chatbot. We use state-of-the-art Pure Language Processing (NLP) strategies to grasp the content material higher.

# Mix textual content from completely different information

def combine_text(text_list):
    return "n".be part of(text_list)

# Cut up textual content into chunks
def get_text_chunks(textual content):
    text_splitter = CharacterTextSplitter(
    chunks = text_splitter.split_text(textual content)
    return chunks

Creating vector retailer

Our venture seamlessly integrates Hugging Face fashions and LangChain for optimum efficiency.

def get_vectorstore(text_chunks):
   #embeddings = OpenAIEmbeddings()
    embeddings = HuggingFaceInstructEmbeddings(model_name="hkunlp/instructor-xl")
    vectorstore = FAISS.from_texts(texts=text_chunks, embedding=embeddings)
    return vectorstore

4.4 Constructing a Conversational AI Mannequin

To allow our chatbot to supply significant responses, we want a conversational AI mannequin. On this venture, we use a mannequin from Hugging Face’s mannequin hub. Right here’s how we arrange the conversational AI mannequin:

def get_conversation_chain(vectorstore):
    # llm = ChatOpenAI()
    llm = HuggingFaceHub(
    model_kwargs={"temperature": 0.5,
     "max_length": 512})
    reminiscence = ConversationBufferMemory(
    conversation_chain = Conversational
    return conversation_chain

4.5 Answering Person Queries

Customers can ask questions associated to the paperwork they’ve uploaded. The chatbot makes use of its information base and NLP fashions to supply related solutions in real-time. Right here’s how we deal with consumer i

def handle_userinput(user_question):
    if st.session_state.dialog shouldn't be None:
        response = st.session_state.dialog({'query': user_question})
        st.session_state.chat_history = response['chat_history']

        for i, message in enumerate(st.session_state.chat_history):
            if i % 2 == 0:
                    "{{MSG}}", message.content material), unsafe_allow_html=True)
                    "{{MSG}}", message.content material), unsafe_allow_html=True)
        # Deal with the case when dialog shouldn't be initialized
        st.write("Please add and course of your paperwork first.")

4.6 Deploying the Chatbot with Streamlit

We’ve deployed the chatbot utilizing Streamlit, a improbable Python library for creating net functions with minimal effort. Customers can add their paperwork and ask questions. The chatbot will generate responses based mostly on the content material of the paperwork. Right here’s how we arrange the Streamlit app:

def predominant():
        page_title="File Chatbot",
    st.write(css, unsafe_allow_html=True)

    if "dialog" not in st.session_state:
        st.session_state.dialog = None
    if "chat_history" not in st.session_state:
        st.session_state.chat_history = None

    st.header("Chat together with your a number of information:")
    user_question = st.text_input("Ask a query about your paperwork:")

    # Initialize variables to carry uploaded information
    csv_file = None
    other_files = []

    with st.sidebar:
        st.subheader("Your paperwork")
        information = st.file_uploader(
            "Add your information right here and click on on 'Course of'", accept_multiple_files=True)
        for file in information:
            if file.title.decrease().endswith('.csv'):
                csv_file = file  # Retailer the CSV file

                other_files.append(file)  # Retailer different file varieties

        # Initialize empty lists for every file kind
        pdf_texts = []
        word_texts = []
        txt_texts = []

        if st.button("Course of"):
            with st.spinner("Processing"):
                for file in other_files:
                    if file.title.decrease().endswith('.pdf'):
                    elif file.title.decrease().endswith('.docx'):
                    elif file.title.decrease().endswith('.txt'):

                # Mix textual content from completely different file varieties
                combined_text = combine_text(pdf_texts + word_texts + txt_texts)

                # Cut up the mixed textual content into chunks
                text_chunks = get_text_chunks(combined_text)

                # Create vector retailer and dialog chain if non-CSV paperwork are uploaded
                if len(other_files) > 0:
                    vectorstore = get_vectorstore(text_chunks)
                    st.session_state.dialog = get_conversation_chain(vectorstore)
                    vectorstore = None  # No want for vectorstore with CSV file

    # Deal with consumer enter for CSV file individually
    if csv_file shouldn't be None and user_question:
        handle_csv_file(csv_file, user_question)
    # Deal with consumer enter for text-based information
    if user_question:

if __name__ == '__main__':
  • Importing a number of information concurrently, together with CSV information, permitting for various doc varieties in a single session(refer: paperwork processing pic).
