Pygame won't import my sprite (AttributeError)

Question

I keep getting an attribute error "AttributeError: 'str' object has no attribute 'convert'" whenever I try to load in my sprite image.

This is how the aforementioned line looks

self.image = pygame.transform.scale(pygame.image.load('assets/R1.png').convert_alpha(), (45, 80))
self.rect = self.image.get_rect()
