Latest commit

* Properly validate a config value against the type of its default

We also properly calculate the `is_default` field. It used to be mostly
True which caused some environment variables to not be included in config_vars

* Fix handling of bools in configurations

* Set debug flags as booleans

Metaflow

Metaflow is a human-friendly library that helps scientists and engineers build and manage real-life data science projects. Metaflow was originally developed at Netflix to boost productivity of data scientists who work on a wide variety of projects from classical statistics to state-of-the-art deep learning.

For more information, see Metaflow's website and documentation.

From prototype to production (and back)

Metaflow provides a simple, friendly API that covers foundational needs of ML, AI, and data science projects:

  1. Rapid local prototyping, support for notebooks, and built-in experiment tracking and versioning.
  2. Horizontal and vertical scalability to the cloud, utilizing both CPUs and GPUs, and fast data access.
  3. Managing dependencies and one-click deployments to highly available production orchestrators.

Getting started

Getting up and running is easy. If you don't know where to start, Metaflow sandbox will have you running and exploring Metaflow in seconds.

Installing Metaflow in your Python environment

To install Metaflow in your local environment, you can install from PyPi:

pip install metaflow

Alternatively, you can also install from conda-forge:

conda install -c conda-forge metaflow

If you are eager to try out Metaflow in practice, you can start with the tutorial. After the tutorial, you can learn more about how Metaflow works here.

Deploying infrastructure for Metaflow in your cloud

While you can get started with Metaflow easily on your laptop, the main benefits of Metaflow lie in its ability to scale out to external compute clusters and to deploy to production-grade workflow orchestrators. To benefit from these features, follow this guide to configure Metaflow and the infrastructure behind it appropriately.
