tick is a Python 3 module for statistical learning, with a particular emphasis on time-dependent modeling. It is distributed under the 3-Clause BSD license, see LICENSE.txt.

The project was started in 2016 by Emmanuel Bacry, Martin Bompaire, Stéphane Gaïffas and Søren Vinther Poulsen at the Datascience initiative of École Polytechnique, France. The list of contributors is available in

Quick description

tick is a machine learning library for Python 3. The focus is on statistical learning for time dependent systems, such as point processes. Tick features also tools for generalized linear models and a generic optimization toolbox. The core of the library is an optimization module providing model computational classes, solvers and proximal operators for regularization. It comes also with inference and simulation tools intended for end-users who for example can easily:

intel logo

The tick library is released with the support of Intel®. It uses the Intel® Math Kernel Library (MKL) optimized for Intel® Xeon Phi™ and Intel® Xeon™ processors. tick runs efficiently on everything from desktop computers to powerful high-performance servers.

Use cases

tick is used for many industrial applications including:

Quick setup


tick currently works on Linux/OSX (Windows is experimental) systems and requires Python 3.5 or newer. Please have the required Python dependencies in your Python environment:

Install using pip

tick is available via pip. In your local Python environment (or global, with sudo rights), do:

pip install tick

Installation may take a few minutes to build and link C++ extensions. At this point tick should be ready to use available (if necessary, you can add tick to the PYTHONPATH as explained below).

Verify install

Run the following command and there should be no error

python3 -c "import tick;"

Source Installation

Please see the INSTALL document

Help and Support


Documentation is available on

This documentation is built with Sphinx and can be compiled and used locally by running make html from within the doc directory. This obviously needs to have Sphinx installed. Several tutorials and code-samples are available in the documentation.
