Некорректно работает ProgressBar

Question

Написал, что-то вроде нейрона, который учится, в моем случае переводить километры в мили.
Написал для него набросок интерфейса и столкнулся с проблемой, что неправильно работает progressBar, то есть он просто очень быстро доходит до 100, но при этом нейрон еще не обучился.

Для обучения необходим цикл while и из-за него скорее всего не работает progressBar, ибо в цикле for, он знает где ему остановится.

Знаю, что трудно разобраться в моем этом бреду. Но прошу знающих людей помочь. Нужно чтобы он останавливался по завершению обучения нейрона.

Нельзя использовать цикл while(True) в основном потоке - это замораживает интерфейс.
