Issue setting up python environment for standalone use on a Linux machine #119
Description
Hi Fredrik and team, has been a while!
I'm getting back into some SOLWEIG involved work, and I'm having trouble setting up an environment that works...
If I set up a python 3.12 based env (which I believe is what is needed for the latest UMEP processing?), then I run into issues with the gsl package (see the error below). However, if I constrain my setup with gsl==2.6 (which eliminates the error below), then I run into all sorts of other problems trying to get python and qgis and gdal to play nice.
Any thoughts?
Cheers from Tasmania
Ben
