Unknown type issue

Thanks for sharing this greak research! I tried to run benchmark-like code and faced this error:

    outputs = self.model(return_loss=False, rescale=True, **data)

    raise Exception(f'Unknown type {type(input)}.')
Exception: Unknown type <class 'dict'>.

Do you have an idea what could cause such an issue?

It was an input format error
