У меня есть конечный автомат, который должен случайным образом выбирать состояние для входа, однако я получаю следующую ошибку типа:
несвязанный метод ToTransition () должен вызываться с экземпляром FSM в качестве первого аргумента (вместо этого есть экземпляр str)
Я не уверен, почему это происходит.При инициации он может вызвать первое состояние, но затем завершается ошибкой.Любой совет будет оценен.
