Relax requirements

[behrisch]

The current requirements ['numpy~=2.2', 'shapely~=2.0', 'pyside6~=6.8', 'vtk~=9.4', 'deprecated~=1.2.18'] are quite strict with the needed versions and also enforce the large GUI packages (pyside and vtk) which I would consider optional. Since SUMO depends now on the jupedsim python package we would like to reduce the dependencies a little and also not force our users to change their numpy if not necessary. So would something like ['numpy>=1.26', 'shapely>=2.0', 'deprecated>=1.2.14'] work for you? You could still declare optional dependencies for pyside6 and vtk and recommend the installation of jupedsim[gui].
This relaxation would allow users to work with the python package versions which come with ubuntu 24.04 and ubuntu 26.04 and in my (very limited) tests using the python scripts generated by the new SUMO coupling I did not encounter any problems.

We need to check. >= is always a bit scary as you never know whether a new major version breaks backwards compatibility. We can make more checks regarding minimal version and also restrict the "highest" version. This will take a bit of time. And it will require a new JuPedSim 1.x release. we will get back to you on this.

I think this is more about dropping VTK / QT from requirements. We can do this for 2.0 since visualization needs a post 2.0 overhaul in any case.

No it is not only about VTK / Qt. We want our users to be able to run the SUMO tools on our "reference platform" (currently ubuntu 24.04) with using as many platform packages (deb) as possible. So ideally they only need to install via pip the things which do not have a deb package.
This is mainly to avoid library conflicts, so you don't need to have a different virtual environment for every task you want to do with SUMO. Ubuntu 24.04 ships numpy 1.26.4 and as far as I can tell the part of jupedsim SUMO needs, works with that. So maybe you could relax the "minimum" requirements (the ones which are enforced when you just do pip install jupedsim) and define additional variants like jupedsim[gui] and/or jupedsim[all] which are stricter?
