Cookiecutter Modern Data Science

Cookiecutter template for starting a Data Science project with modern, fast Python tools.

Features

• Pipenv for managing packages and virtualenvs in a modern way.
• Prefect for modern pipelines and data workflow.
• Weights and Biases for experiment tracking.
• FastAPI for self-documenting fast HTTP APIs - on par with NodeJS and Go - based on asyncio, ASGI, and uvicorn.
• Modern CLI with Typer.
• Batteries included: Pandas, numpy, scipy, seaborn, and jupyterlab already installed.
• Consistent code quality: black, isort, autoflake, and pylint already installed.
• Pytest for testing.
• GitHub Pages for the public website.

Quickstart

Install the latest Cookiecutter and Pipenv:

pip install -U pipenv cookiecutter

Generate the project:

cookiecutter gh:crmne/cookiecutter-modern-datascience

Get inside the project:

cd <repo_name>
pipenv shell  # activates virtualenv

(Optional) Start Weights & Biases locally, if you don't want to use the cloud/on-premise version:

wandb local

Start working:

jupyter-lab
