шот сложное тут творишь. плюс, захардкожены классы. ты либо все сделай флат, отфильтруй -1, а потом экспанд дименшин сделай, чтобы количество размерностей подходящее было. Либо в лоссах делай умножение на 0, в позициях для -1

лямбды тут не нужно использовать. ты ж можешь просто присвоить саму функцию с лоссом.
