Проблема с приложением Raspberry Pi Python / Pygame не будет запускаться при загрузке, потому что pygame.error

Question

У меня проблемы с загрузкой приложения при загрузке. Я использую xterm на raspberry pi, и приложение очень близко к загрузке, но затем завершается неудачно и говорит, что pygame.error не может загрузить «filename.png». есть идеи почему? Я занимаюсь этим уже несколько дней и не могу понять, как заставить его загружаться при запуске ...

вот мой код.
