Cookiecutter Data Science

A logical, reasonably standardized, but flexible project structure for doing and sharing data science work.

Standard Naming Convention

Files should be named according to the person who is creating them, version numbers, and the purpose. For example:

• notebooks/ak-1.2-DataPreprocessing.py
• data/interim/ak-1.2-DataPreprocessing.csv
• logs/ak-1.2-DataPreprocessing/GENERATED_FILES

Your initials (preferably first two), the notebook number (in chronological order of creation) and version number (incremented any time you make changes that would effect the output, and the type of file.

Common file names

• DataPreprocessing - manipulating the raw data files into standard Pandas Dataframe form
• DataExploration - for looking at the contents of the data, usually raw but could be other
• ModelX - running a particular model
• ParameterTuning - sweeping across hyperparameters
• Scratch - personal playground, not expected to be production ready at any point

Project homepage

Requirements to use the cookiecutter template:

---

• Python 2.7 or 3
• Cookiecutter Python package >= 1.4.0: This can be installed with pip by or conda depending on how you manage your Python packages:

$ pip install cookiecutter

or

$ conda config --add channels conda-forge
$ conda install cookiecutter

To start a new project, run:
