Stratosphere

A lightweight experimentation toolkit for data scientists.

Designed to be accessibile, fast and robust. stratosphere lets you:

1. Define as code your experiments: s.define(name="experiment", funcs=[step1, step2, step3])
2. Execute them with the best-suited backend: s.execute()
3. Track what you need (predictions, metrics, ...)
4. Store them as plain tables and/or pickled objects
5. Query them with SQL, Pandas or Python

How is it possible?

• Fast and light: Try it now with JupyterLite, it runs entirely in the browser
• Built on top of solid components: SQLAlchemy, SQLite, Pandas, Joblib and Dask
• Designed for data accessibility: Use it where you need it. For example, you can experiment in-memory, persist locally, replicate tables on render.com, and publish results on preset.io (all free tiers!)

Installation

On Python >= 3.8.0:

• With PyPI: pip install "stratosphere[complete]" --upgrade # Install everything
• With Poetry: poetry add stratosphere@latest --extras complete # Install everything

On Python 3.7.13-15 (Google Colab, Binder):

!pip install joblib pandas tqdm cloudpickle colorama sqlalchemy sqlalchemy-utils ulid-py --upgrade --quiet
!pip install tabulate scikit-learn dask[complete] --upgrade --quiet # to install extras
!pip install stratosphere --ignore-requires-python --no-dependencies --quiet

You can also install only the stratosphere library (dropping the [complete] extras). Modules like stratosphere.utils.dask, stratosphere.utils.metrics, and stratosphere.utils.widgets won't work until you also install dask[complete], scikit-learn, and ipywidgets, respectively. These extras are required to run some of the tutorial notebooks.

Documentation

• In the intro notebook, you'll be exposed to the key concepts. It runs entirely in the browser.
• In the tutorial notebooks, you'll cover the advanced topics. Working locally, on Colab and on Binder.
