Fix set up

The current set up of the software contains some errors, e.g., failures in script naming etc.
I recommend to set up a continuous integration pipeline (for instance with GitHub Actions) to make sure, the software can at least be installed, if not tested.

BTW, it would be great if the documentation would explain how to use the software. I can see two scripts on the top level, but I guess these are only used during training. Which other executables are needed to use Modelizer?

Additionally, as a software engineer, I would appreciate a clean separation of the setup and the runtime. At least the training scripts on the top level execute the full installation on each execution. Of course, it gets faster over time as the Python stuff is cached. Nevertheless, the setup should only be executed once in order to run the software.

Let me allow for a third recommendation: A virtual Python environment should be created in order not to interfere with other Python software installations. venv or Conda might be worth mentioning in the setup instructions.
