Description

The Conversational Q&A Chatbot we are building combines the user-friendly interface of Streamlit with the advanced natural language processing capabilities of the GPT-3.5-turbo model. Users can interact with the chatbot by posing questions, and the model will generate contextually relevant responses conversationally. This project showcases the potential of integrating cutting-edge language models into practical applications, making it ideal for various use cases, from customer support to educational platforms.

Prerequisites

Before we begin, make sure you have the following:

Python installed on your machine (version 3.6 or higher).
An OpenAI account and the API key (OPENAI_API_KEY) accessible.

Step-by-Step Guide

Step 1: Installation

Setting Up the Environment

Install Streamlit
bash

1 2	Install Streamlit bash

pip install streamlit

1	pip install streamlit

Install OpenAI Python SDK
bash

1 2	Install OpenAI Python SDK bash

pip install openai

1	pip install openai

Install Langchain
bash

1 2	Install Langchain bash

pip install langchain

1	pip install langchain

Step 2: Implementation

Writing the Streamlit App
Now, let’s create the Streamlit application. Create a file named app.py and follow the following step:

Required libraries

#conversational Q&A Chatbot
import streamlit as st
from langchain.schema import HumanMessage,SystemMessage,AIMessage
from langchain_openai import ChatOpenAI 
from dotenv import load_dotenv
import os

#conversational Q&A Chatbot

import streamlit as st

from langchain.schema import HumanMessage,SystemMessage,AIMessage

from langchain_openai import ChatOpenAI

from dotenv import load_dotenv

import os

create .env file
variable:

‘OPEN_API_KEY’=’YOUR_OPENAI_API_KEY’

Replace “YOUR_OPENAI_API_KEY” with your actual OpenAI API key.

Load the environment variable

load_dotenv()

1	load_dotenv()

Defining Function to Get OpenAI Response

chat=ChatOpenAI(temperature=0.8) 
def get_openai_response(question):
    st.session_state['flowmessages'].append(
    HumanMessage(content=question))
    answer=chat(st.session_state['flowmessages'])
    st.session_state['flowmessages'].append(AIMessage(
    content=answer.content))
    return answer.content

chat=ChatOpenAI(temperature=0.8)

def get_openai_response(question):

st.session_state['flowmessages'].append(

HumanMessage(content=question))

answer=chat(st.session_state['flowmessages'])

st.session_state['flowmessages'].append(AIMessage(

content=answer.content))

return answer.content

Set up UI and session state

st.set_page_config(page_title="coversational Q&A Chatbot")
st.header("hi lets have a Chat")

if 'flowmessages' not in st.session_state:
    st.session_state['flowmessages']=[
        SystemMessage(content= 'you are AI Assistant')
    ]

st.set_page_config(page_title="coversational Q&A Chatbot")

st.header("hi lets have a Chat")

if 'flowmessages' not in st.session_state:

st.session_state['flowmessages']=[

SystemMessage(content= 'you are AI Assistant')

]

Handling User Input and Displaying Response

input=st.text_input('Input:', key='input')
response=get_openai_response(input)

submit=st.button('Ask me question')
if submit:
    st.subheader("The Response is")
    st.write(response)

input=st.text_input('Input:', key='input')

response=get_openai_response(input)

submit=st.button('Ask me question')

if submit:

st.subheader("The Response is")

st.write(response)

Step 3: Running the Application

Save the app.py file and run the following command in your terminal:

bash

bash

streamlit run app.py

1	streamlit run app.py

Step 4: Visit the provided URL in your web browser to interact with your chatbot
