Судя по коду у вас опечатка.
Вот тут вы создаёте переменную типа "словарь"
Svm_model = {}
Вот тут вы вызываете метод, которого нет у словаря.
Svm_model.fit()

Скорее всего вам нужно тут вызвать конструктор класса, который вы потом начнёте обучаюсь вызвав метод fit(), например так.
Svm_model = LinearRegression()
