different subimage number obtained after running 'extract_subimages.py' for X3_sub #5
Description
After processing by running 'scripts/data_preparation/extract_subimages.py', totally obtained image number in 'datasets/DF2K/DF2K_train_LR_bicubic/X3_sub' is different from that in 'datasets/DF2K/DF2K_train_HR_sub'. So that error occurred when training launched. Yet, image numbers in 'X3_sub' and 'X4_sub' are same as that in 'HR_sub', after processing data . Are parameters below right?
