This Chatbot is an AI-powered chatbot that can assist users with various queries. It uses OpenAI's GPT-3.5-turbo model for generating responses and integrates with a web interface built using Flask and a desktop interface using Tkinter.

Features

• Web scraping using Selenium
• Text processing with NLTK
• Embedding creation with OpenAI
• Web interface with Flask
• Desktop interface with Tkinter

Prerequisites

• Python 3.10 or higher
• pip (Python package installer)
• Chrome browser (for Selenium)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/ricks-chatbot.git
   cd ricks-chatbot

2. Create and activate a virtual environment:

   python3 -m venv botenv
   source botenv/bin/activate  # On Windows use `botenv\Scripts\activate`

3. Install required packages:

   pip install -r requirements.txt

4. Set up environment variables:

   • Create a .env file in the root directory and add your OpenAI API key:

   OPENAI_API_KEY=your-actual-openai-api-key
   

5. Download NLTK data:

   python -m nltk.downloader punkt averaged_perceptron_tagger popular averaged_perceptron_tagger_eng

Running the Chatbot

Step 1: Scrape Data and Create Embeddings

1. Run the bot_web.py script to scrape data and create embeddings:

   python bot_web.py

   This script will:

   • Scrape data from specified URLs
   • Store the scraped data in data.txt
   • Create embeddings and save them in PKL_file

Step 2: Start the Flask Server

1. Start the Flask server:

   python app.py

2. Open your browser and navigate to:

   http://localhost:2023
   

Step 3: Interact with the Chatbot

1. Use the web interface to interact with the chatbot.

Troubleshooting

1. NLTK Data Not Found:

   • Ensure you have downloaded the required NLTK data:

   python -m nltk.downloader punkt averaged_perceptron_tagger popular averaged_perceptron_tagger_eng

2. Invalid OpenAI API Key:

   • Make sure your .env file contains a valid OpenAI API key.

3. Selenium WebDriver Issues:

   • Ensure you have Chrome installed and the correct version of ChromeDriver.
