If you performed a training with this configuration, I guess the network did not learn much, since 40 patches are definitely not enough data. I usually perform the training with at least 100000 patches (but a GPU is strongly recommended in this case) However, I fix the script so it will not crash in case of division by zero.
Thank you very much. And I am confuse that TWO settings are connected? ( some combination? ) I hope you don't mind mine poor ENG.
[data attributes]
patch_height = 48 patch_width = 48

N_subimgs = 175000 (100,000 at least)
Nope, N_subimgs is the number of 48x48 patches extracted at random from the training images.
ok, thanks

What should I do? Thanks for any help.
