Hi, I would add a change to your code by adding intensity normalization for test images.
img = load_img(path,False,target_size=(img_width,img_height))
x = img_to_array(img)
x= x / 255
x = np.expand_dims(x, axis=0)
The training images had this normalisation, therefore the test images should go through it too.
Thanks for the code.

Hello @ritazh and @barnajit. Could you explain to me what the range means (1401, 1411)? How to determine this value?

Thanks for the code.

hello I am Trying to use the classificator, but in the last part I get the follow error: predict() fp = builtins.open(filename, "rb") PermissionError: [Errno 13] Permission denied:
Some recommendation for the path route?, I found that this error could be admin permision, but I don't know...
I appreciate your help,
Best regards,

RM
