I'm trying to access the frames property to find the winner of a game and I get this error:

Code used to get the error:

from slippi import Game

game = Game("./replays/test2.slp")

print(game.frames[0])

Python version: 3.11.1

I just encountered this after upgrading Python myself. Based on the name, _decompose is a private function of the enum library, and should never have been used by py-slippi in the first place. I assume it was removed in some recent Python version, and now py-slippi is not working.

Here is a corrected version of the IntFlag.__repr__ function using only documented attributes of the enum library:

def __repr__(self):
    members = (name for name, value in self.__class__.__members__.items() if self & value)
    return '%s:%s' % (bin(self._value_), '|'.join(members))

Until this is, hopefully soon, fixed in the library, you can monkey patch the fix into your code with:

slippi.util.IntFlag.__repr__ = fixed_repr
