Why is importlib not able to import a module two levels up

I am trying to import a module with importlib but I am get No module named 'configuration'
This is my directory I am trying to run app.py which loads configuration two levels up

I tried using

importlib.import_module( 'configuration' )
configuration_module = importlib.import_module( '.config_loader', package='configuration' )

it's not able to load configuration

--home
    ---configuration
             ---config.py
              --- init.py
    ---restful
              --- init.py
               ---application
                    --- app.py
                    --- config.py
                    --- __init__py

    Traceback (most recent call last):
  File "application/app.py", line 214, in <module>
    app = create_app()
  File "application/app.py", line 39, in create_app
