⚙️ Setup

This project was developed using Python v3.12.3. If you encounter issues running the specified version of dependencies, consider using this specific Python version.

📝 List of Dependencies

Installing matplotlib and pandas is OPTIONAL. They are used exclusively in the Looking Ahead Notebook to show an application of using them.

📦 Installing Dependencies

You can install all dependencies listed in requirements.txt using pip:

pip install -r requirements.txt

🛠️ Usage Instructions

1. Open the root folder with VS Code:
   • Windows/Linux: Ctrl + K followed by Ctrl + O
   • macOS: Cmd + K followed by Cmd + O
2. Open .ipynb files using Jupyter extension integrated with VS Code.
3. Allow VS Code to install any recommended dependencies for working with Jupyter Notebooks.
