Welcome to Langchain QA System

Prerequisites

You should make sure Python 3.11 is already installed on your local machine. And plus, python3.11-venv must be installed.

Setup

  1. clone the repository from GitHub.
git clone https://github.com/eagerbeaver53/langchain-qa-system.git
cd langchain-qa-system/
  1. Create python virtual environment.
# I would like to create virtual environment using python3.11-venv.
pip install --upgrade pip
python -m venv env
source env/bin/activate
  1. Install required packages.
pip install -r requirements.txt

All done successfully!!! Now you can finish setting up the project.

Usage

  1. Create environment variable for the project.
cp example.env .env

  1. Edit the environment variable with your options.

  2. Paste the JSON file of predefined questions and answers in any directory.

  • OPENAI_API_KEY: OpenAI API Key
  • CHROMA_DB_DIRECTORY: The location of The local ChromaDB vectorstore.
  1. Run app/main.py file in the virtual environment.
source env/bin/activate
gunicorn --bind 0.0.0.0:8000 app.main:app -k uvicorn.workers.UvicornWorker --timeout 1500 --reload

Cautions

  • The ChromaDB doesn't care about the double storing of same documents so please make sure you don't store same documents twice.
  • If you want to embed documents to new database, Deleting CHROMA_DB_DIRECTORY will be the solution.

Good luck to you with my project!!!
