Setting up the Development Environment

Below are key steps to set up the development environment for building a Streamlit Chatbot Application with OpenAI and Elasticsearch:

Install Streamlit: Begin by installing Streamlit using pip install streamlit in your Python environment. Streamlit simplifies the creation of interactive web applications and serves as the foundation for your chatbot interface.
OpenAI API Access: Obtain access to the OpenAI API by signing up on the OpenAI platform. Retrieve your API key, which will enable your application to leverage OpenAI’s natural language processing capabilities for intelligent chatbot responses.
Set up Elasticsearch: Install and configure Elasticsearch, a powerful search engine, to enhance your chatbot’s capabilities. You can download Elasticsearch from the official website and follow the setup instructions to get it running locally.
Dependencies: Ensure you have the necessary Python libraries installed, including those required for interfacing with OpenAI (e.g., openai library) and connecting to Elasticsearch (e.g., elasticsearch library).

How To Build a Chatbot

Building a chatbot that integrates Elasticsearch for information retrieval and OpenAI’s LangChain for advanced natural language processing involves several steps. Below is a simplified example using Python, Streamlit for the interface, and the elasticsearch and openai libraries.

Step 1: Install Required Libraries

pip install streamlit openai elasticsearch

Step 2: Set Up Elasticsearch Connection

pip install elasticsearch

Step 3: Update OpenAI API Key

Update your_openai_api_key in code using OpenAI API key from the OpenAI platform

Step 4: Create a Streamlit App

import streamlit as st
import openai
from elasticsearch import Elasticsearch

# Set up OpenAI API key
openai.api_key = 'your_openai_api_key'

# Set up Elasticsearch connection
es = Elasticsearch()

# Streamlit App
def main():
    st.title("Chatbot using OpenAI and Elasticsearch")

    # User input
    user_input = st.text_input("Question:")

    if st.button("Answer"):
        # Call OpenAI API for generating response
        response = get_openai_response(user_input)

        # Display response
        st.text("Response: " + response)

        # Store the conversation in Elasticsearch
        index_conversation(user_input, response)

# OpenAI API call function
def get_openai_response(user_input):
    prompt = f"User: {user_input}\nChatbot:"
    response = openai.Completion.create(
        engine="text-davinci-003",
        prompt=prompt,
        temperature=0.7,
        max_tokens=150,
        n=1,
    )
    return response['choices'][0]['text'].strip()

# Store conversation in Elasticsearch
def index_conversation(user_input, chatbot_response):
    doc = {
        'user_input': user_input,
        'chatbot_response': chatbot_response
    }
    es.index(index='chat_data', body=doc)

if __name__ == "__main__":
    main()
