How to change the number of classes on semantic segmentation?

[marcellolg1987]

Sorry, I have a problem regarding the possibility to change the number of classes on semseg. The algorithm works fine with 13 classes, but I need to use it with 4 classes. I tried to modify all the necessary config files converting the 13 classes into 4 but it doesn't works. Do you have suggestions?
Thank you in advance!
