Installing borea in the QGIS environment.

Borea is installed in the QGIS environment using pip.

Compatibility

You need to be aware of the compatibility of python versions and python libraries.

  • python >= 3.9
  • gdal >= 3.3.2
  • numpy <= 1.26.4

Check that your QGIS uses a version of python higher than 3.9 .
To see this:

  • you can open QGIS and click on Help, then About you should see the version of python and GDAL.
  • If not, go to the C:\Program File\QGIS{n°version}\apps folder, where you'll find a Pyhton{n°version} folder.
    If you want to know more about the python version and libraries. Enter the folder, open a terminal in this folder (type cmd in the path bar), then in the terminal type python --version for the python version and python -m pip list to see the python libraries linked to QGIS.

Installation by linking the QGIS environment to your terminal

To do this, you need the path to the QGIS python folder, which should look like C:\Program File\QGIS{n°version}\apps\Python{n°version} and inside you'll find a python executable, a Scripts folder, Lib ... and in the Lib folder a site-package or ...-package folder containing folders for python libraries such as numpy.

The paths must be added to the Path variable:

  • C:\Program Files\QGIS{n°version}\apps\Python{n°version}\
  • C:\Program Files\QGIS{n°version}\apps\Python{n°version}\Scripts

And create a new PYTHONPATH variable with the path C:\Program Files\QGIS{n°version}\apps\Python{n°version}\Lib\site-packages

Warning, change the paths according to your needs - this is just an example.

You can open a terminal and use the python and pip commands, which will be linked to your QGIS environment. You can check with python --version to see if you have the QGIS python version, or core pip list to see all the python libraries used by QGIS

All you have to do is:

pip install ign-borea

to use it in QGIS with executables.

Link details

  • C:\Program Files\QGIS{n°version}\apps\Python{n°version}\ : allows you to use QGIS python with the python command.
  • C:\Program Files\QGIS{n°version}\apps\Python{n°version}\Scripts: use executables linked to this environment (e.g. opk-to-opk -h or pip this is what allows you to make a pip list and see the QGIS python environment).
  • C:\Program Files\QGIS{n°version}\apps\Python{n°version}\Lib\site-packages : allows you to link python packages from the QGIS environment to python (borea, numpy, ...).
