SimpleChatBot

A sandbox repository showcasing different implementations of simple chatbots using LangChain and LangGraph.

Introduction

This repository contains local implementations of chatbots, where each chatbot builds off the other through basic components including prompt templates & short term memory.

Naive Chat Bot (naiveChatBot.py)

This is a simple chatbot that uses Ollama as its model, specifically Llama 3.2. It serves as a starting point for understanding how to integrate LangChain with an LLM.

One notable aspect of this implementation is the absence of short-term memory. The chatbot only processes user input and generates responses based on the current context, without retaining any information from previous interactions. This design choice allows for a straightforward demonstration of using Ollama with LangChain.

Lang Graph Memory Bot (langGraphMemBot.py)

This implementation builds upon the previous one by incorporating short-term memory capabilities. The Lang Graph Memory Bot uses the langGraph library to enable context-dependent responses.

By leveraging Lang Graph's architecture, this chatbot demonstrates a more advanced approach to NLP, where the model can retain information from previous interactions and generate more informed responses.

Getting Started

To replicate this repository, please follow these steps:

1. Install Required Dependencies

Create a new virtual environment using python -m venv myenv (or your preferred method). Activate the environment: source myenv/bin/activate (on Linux/Mac) or myenv\Scripts\activate (on Windows).

Install the required dependencies by running: pip install -r requirements.txt

2. Download and Install Ollama

Visit the official Llama repository: https://github.com/facebookresearch/ollama

Download the pre-trained model for your desired language and architecture.

Follow the instructions in README.md to install and configure Ollama.

3. Clone this Repository

Fork the SimpleChatBot repository using Git: git fork https://github.com/[your-username]/SimpleChatBot

Please note that you'll need to replace [your-username] with your actual GitHub username.

Requirements

To run the chatbots, ensure you have Python 3.9+ installed on your system. Additionally, please make sure Ollama is properly installed and configured before proceeding.
