Может ли кто-нибудь помочь мне с этой проблемой многоклассовой семантической сегментации.Я изменил код, чтобы принимать изображения RGB и метки RGB в качестве масок.Я использую следующую модель

Как видите, вход имеет 3 канала.Должен ли последний слой иметь 1 канал из 11 каналов?Набор данных, который я использую, содержит 11 классов, которые обозначены различными комбинациями значений RGB в изображении.
Спасибо.
