Setup

Conda

• Install anaconda
• This repo was tested on a Mac with python=3.11.
• Create an environment: conda create -n oreilly-chatgpt-apps python=3.11
• Activate your environment with: conda activate oreilly-chatgpt-apps
• Install requirements with: pip install -r requirements.txt
• Setup your openai API key

Pip

1. Create a Virtual Environment: Navigate to your project directory. Make sure you have python 3.11 installed! If using Python 3's built-in venv:

   python -m venv oreilly-chatgpt-apps

   If you're using virtualenv:

   virtualenv oreilly-chatgpt-apps

2. Activate the Virtual Environment:

   • On Windows:

     .\oreilly-chatgpt-apps\Scripts\activate

   • On macOS and Linux:

     source oreilly-chatgpt-apps/bin/activate

3. Install Dependencies from requirements.txt:

   pip install python-dotenv
   pip install -r requirements.txt

4. Setup your openai API key

Remember to deactivate the virtual environment once you're done by simply typing:

deactivate

Setup your .env file

• Change the .env.example file to .env and add your OpenAI API key.
