Anovos is an open source library for feature engineering at scale. Built by data scientists & ML Engineers for the data science community, it provides all the capabilities required for data ingestion, data analysis, data drift & data stability analysis, feature recommendation and feature composition. In addition, it automatically produces easily interpretable professional data reports that help users understand the nature of data at first sight and further enable data scientists to identify and engineer features.

Leveraging the power of Apache Spark behind the scenes, Anovos improves data scientists' productivity and helps them build more resilient and better performing models.

Quick Start

The easiest way to try out Anovos and explore its capabilities is through the provided examples that you can run via Docker without the need to install anything on your local machine.

# Launch an anovos-examples Docker container
sudo docker run -p 8888:8888 anovos/anovos-examples-3.2.2:latest

To reach the Jupyter environment, open the link to generated by the Jupyter NotebookApp.

If you're not familiar with Anovos or feature engineering, the Getting Started with Anovos guide is a good place to begin your journey. You can find it in the /guides folder within the Jupyter environment.

For more detailed instructions on how to install Docker and how to troubleshoot potential issues, see the examples README.

Using Anovos


To use Anovos, you need compatible versions of Apache Spark, Java and Python.

Currently, we officially support the following combinations:

  • Apache Spark 2.4.x on Java 8 with Python 3.7.x
  • Apache Spark 3.1.x on Java 11 with Python 3.9.x
  • Apache Spark 3.2.x on Java 11 with Python 3.10.x

To see what we're currently testing, see this configuration.


You can install the latest release of Anovos directly through PyPI:

pip install anovos


We provide a comprehensive documentation at that includes user guides as well as a detailed API documentation.

For usage examples, see the provided interactive guides and Jupyter notebooks as well as the Spark demo.
