KIE: question about num_classes parameter

[piarosebelledelapaz]

问题描述 / Problem Description

hello, i would like to ask what the num_classes parameter is about in the config files for SER.

i am using my custom dataset for training SER and RE but i get an error when i change the num_classes parameter in the config file. i also provided my own class_list.txt which contains:

NAME
DATE

so i only have 2 classes. i saw in one of the code comments that for num_classes, it should be 2n-1 where n is the number of classes. so since i have two, i changed the parameter to 3 instead of 7 (original value). but now i get an error.

when i switch it back to 7 i can do the training and no error occurs. i want to clarify if changing this value would affect the results, thank you for your help in advance
