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/macOS

Installation options include pip and conda.

Debian/Ubuntu

Packages should be available from default repositories but our repository will always provide the latest version. This also applies to other Debian/Ubuntu-based distributions like Linux Mint, Kali Linux, ParrotOS, PureOS, Raspberry Pi OS, … First create an entry in the apt configuration matching your distribution family and codename if available in one of the following commands:

echo deb [signed-by=/usr/share/keyrings/openturns-keyring.gpg] https://openturns.github.io/apt/ubuntu resolute main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb [signed-by=/usr/share/keyrings/openturns-keyring.gpg] https://openturns.github.io/apt/ubuntu noble main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb [signed-by=/usr/share/keyrings/openturns-keyring.gpg] https://openturns.github.io/apt/ubuntu jammy main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb [signed-by=/usr/share/keyrings/openturns-keyring.gpg] https://openturns.github.io/apt/debian trixie main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb [signed-by=/usr/share/keyrings/openturns-keyring.gpg] https://openturns.github.io/apt/debian bullseye main | sudo tee /etc/apt/sources.list.d/openturns.list
echo deb [signed-by=/usr/share/keyrings/openturns-keyring.gpg] https://openturns.github.io/apt/debian bookworm 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 and update the package database:

sudo apt install -y curl gnupg
curl -fsSL https://openturns.github.io/apt/public.key | sudo gpg --dearmor --yes --output /usr/share/keyrings/openturns-keyring.gpg
sudo apt update

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

Package name	Description
libopenturns0.x	library
libopenturns-dev	development package
python3-openturns	Python module

To install the Python module:

sudo apt install python3-openturns

RPM-based distributions
