Installation

From binary packages

Pip

Install binary packages from PyPI:

pip3 install openturns

For an installation without administrative privileges the option --user can be used. Note that pip does not install pre-releases unless given the option --pre.

Conda

This is relevant to the Conda userland Python package manager.

As binary dependency packages from the conda-forge channel are not compatible with ones from the default channel, openturns packages are not working on top of Anaconda. Instead, we recommend installing conda from Miniforge where conda is configured to prioritize packages from conda-forge out of the box. On Windows just download the matching miniforge exe and follow the instructions, on Linux you can install it from command-line in one go:

wget https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-Linux-x86_64.sh -P /tmp
bash /tmp/Miniforge3-Linux-x86_64.sh -b -p $HOME/miniforge
PATH="$HOME/miniforge/bin:$PATH"

Then it should be ready to install packages:

conda install -y openturns

Note that conda can be slow or fail at resolving complex environments with many packages so when a full upgrade is needed our advice is to create a new environment from scratch.

Alternatively, you can download the otconda bundle containing the library and its modules that allows for an offline installation.

Windows

Download the installer matching your python version and architecture from GitHub Then just run installer and follow the instructions.

A non-interactive installation is also possible with the command line:

openturns-1.20-py38-x86_64.exe /userlevel=1 /S /FORCE /D=%PREFIX%

macOS

Installation options include pip and conda.

Debian/Ubuntu

First create an entry in the apt configuration matching your distribution family and codename if available in one of the following commands:

echo deb https://openturns.github.io/apt/ubuntu jammy main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb https://openturns.github.io/apt/ubuntu focal main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb https://openturns.github.io/apt/debian bookworm main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb https://openturns.github.io/apt/debian bullseye main | sudo tee /etc/apt/sources.list.d/openturns.list

Note

Use the bash command lsb_release -a in order to determine the codename of your distribution.

Then add the mirror signature, enable apt https support and update the package database:

curl -s https://openturns.github.io/apt/public.key | sudo apt-key add -
sudo apt install apt-transport-https
sudo apt update

At this point the following new packages should be available via the package manager:

libopenturns-dev

development package

python3-openturns

Python module

To install the Python module:
