OpenTURNS
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. This can also be achieved with Miniconda with extra steps. 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 (see also Mamba).
Alternatively, you can download the otconda bundle
containing the library and its modules that allows for an offline installation.
Note that pre-releases are published on conda-forge like regular releases, so
if you want to stick to the stable version you will have to explicitly specify
the required version, eg conda install openturns=1.20.
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:
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¶
Add the repository corresponding to your operating system:

rpm --import https://download.opensuse.org/repositories/science:/openturns/Mageia_8/repodata/repomd.xml.key
The following packages are available:
Package name |
Description |
|---|---|
openturns-libs |
library |
openturns-devel |
development package |
python3-openturns |
Python module |
To install the Python module:
yum install python3-openturns
Archlinux¶
Install from AUR:
aurman -S openturns
FreeBSD¶
Install from FreshPorts:
pkg install openturns
Development version¶
From source¶
Install the required External dependencies and build the development branch:
git clone https://github.com/openturns/openturns.git
cd openturns
cmake -DCMAKE_INSTALL_PREFIX=~/.local .
make install
Note
When installing into ~/.local you don’t need to set PYTHONPATH environment variable for Python to be able to import openturns
Weekly builds¶
Weekly built Python binaries are also available with the latest bugfixes and features, but also with new bugs and API changes, use at your own risk:
pip3 install --pre --extra-index-url https://pypi.anaconda.org/openturns-wheels-nightly/simple --upgrade --force-reinstall openturns
