Introduction

This file describes how to use OR-Tools in python with the binary archives.

OR-Tools online documentation is located at https://developers.google.com/optimization

Full installation instructions are located at https://developers.google.com/optimization/install/python/

These modules have been tested under:

  • CentOS 7 LTS and Stream 8 (64 bit).
  • Debian 10 and 11 (64 bit).
  • Fedora 33 and up (64 bit).
  • Opensuse Leap (64 bit).
  • Ubuntu 18.04 LTS and up (64 bit).
  • MacOS 12.5 Monterey (64 bit).
  • Microsoft Windows with Visual Studio 2019 and 2022 (64-bit)

Codemap

Upon decompressing the archive, you will get the following structure:

or-tools/
  [LICENSE](LICENSE)                     <- Apache License.
  [README.md](README.md)                 <- This file.
  [examples/python](examples/python)     <- Python examples.
  [examples/notebook](examples/notebook) <- Jupyter/IPython notebooks.

Warning: While OR-Tools ships with SCIP, please consult the SCIP license to ensure that you are complying with it if you want to use this solver.

Installation

To install the package:

  1. Make sure python and pip are installed

  2. Make sure pip is up to date:

python -m pip -V

should return 9.0.1 otherwise, run: python -m pip install --upgrade --user pip

  1. Fetch ortools from Pypi:
python -m pip install --upgrade --user ortools

It should pull the latest version of OR-Tools.
