Bug描述 Describe the Bug

Trying to bundle a python app using PyInstaller but I got this import error when the application is run:

    from eiseg import controller
  File "PyInstaller\loader\pyimod02_importers.py", line 352, in exec_module
  File "eiseg\controller.py", line 29, in <module>
    from models import EISegModel
ImportError: cannot import name 'EISegModel' from 'models' (unknown location)

I was able to fix this issue by editing the import in line 29 of the controller.py file from from models import EISegModel to from eiseg.models import EISegModel

However, I would like to do this without having to modify manually the eiseg library. Can you fix this?

@simoneorlando Done, but FYI I think packaging eiseg with PyInstaller very difficult (I tried and failed :joy:), good luck bro.
