The python package for Itzï is on pypi. You can browse and download the source code on bitbucket.

Installation on GNU/Linux

Itzï depends on GRASS GIS 7 and NumPy. GRASS should therefore be installed in order to use Itzï. NumPy is normally installed along GRASS. All other dependencies are installed by pip.

To install Itzï, you’ll need to have the Python installation software pip installed. On Ubuntu, the package is called python-pip and is installed as follow:

sudo apt-get install python-pip

Installation for a single user

This is useful when you do not have root access on the computer.

To download and install the last version of Itzï using pip:

pip install itzi --user

If Itzï is already installed and you want to update it to the last version:

pip install itzi --user --upgrade

If you prefer to download and install Itzï manually, you can do it that way:

tar -xvf itzi-17.1.tar.gz
cd itzi-17.1
python install --user


For some reason not related to Itzï, pip does not always place the Itzï executable in an accessible place. If calling itzi returns a command not found error, you need to add the installation directory (usually ~/.local/bin) to your PATH.

Installation for all users

This requires root access. The steps are the same as above, with the addition of the use of sudo:

sudo pip install itzi

Installation on Windows

Itzï can be run on Windows 10 using the Windows Subsystem for Linux (WSL). For that, you’ll need at least Windows 10 64bits Anniversary Update. The Creators Update will save you some steps in the installation.

To install WSL, follow the steps given by Microsoft.

Once WSL is installed, launch the bash command line and check your ubuntu version:

lsb_release -a

If you have Ubuntu 14.04, you’ll first need to add a repository to have access to GRASS 7. This step is not necessary if you have Ubuntu 16.04 (installed if you have Windows Creators Update):

add-apt-repository ppa:ubuntugis/ppa

You can then install the prerequisites:

sudo apt-get update
sudo apt-get install grass-dev grass-core python-pip

Once everything is installed, the installation steps are the same as GNU/Linux.

Verification of the installation

To check if everything went fine:

itzi version
itzi run -h
