LFW dataset put images in different folders based on names. I want to read and move all images to one folder. I used a for loop with os.listdir() function to read the file, but it only returns an image from the first folder in LFW dataset.

'''code is showing below the line'''

 import os
 from os.path import join as pjoin
 from skimage import io
 img_dir = 'new path'
 def load_data(data_dir): #dataset is the originalPath

 count = 0
 for guys in os.listdir(data_dir):
 print(guys)
 person_dir = pjoin(data_dir, guys)
 for i in os.listdir(person_dir):
 image_dir = pjoin(person_dir, i)
 img22 = io.imread(image_dir, mode='RGB')
 print(image_dir)
 io.imsave(pjoin(img_dir, i), img22)
 count = count+1
 print(person_dir)
 print(count)
 return count

 sourcepath = 'originalPath'
 load_data(sourcepath)

The expected result is all images from all folders of LFW dataset are read to the new path (not in any folder, only images.)
The code runs with no error, but the count actually returns '1' and I can see in the new path, there's only 1 image, which was in the first folder of the LFW dataset.

One obvious problem is indentation of your return statement:

'''code is showing below the line'''

 import os
 from os.path import join as pjoin
 from skimage import io
 img_dir = 'new path'
 def load_data(data_dir): #dataset is the originalPath

 count = 0
 for guys in os.listdir(data_dir):
 print(guys)
 person_dir = pjoin(data_dir, guys)
 for i in os.listdir(person_dir):
 image_dir = pjoin(person_dir, i)
 img22 = io.imread(image_dir, mode='RGB')
 print(image_dir)
 io.imsave(pjoin(img_dir, i), img22)
 count = count+1
 print(person_dir)
 print(count)
 return count

 sourcepath = 'originalPath'
 load_data(sourcepath)

Can you check and confirm if the first folder (guys) it is working for has more than one images.

  Thanks a lot, Dinesh. I didn't realize there is a "return count", I was supposed to print(count) and return. After removing the return count the code works well.
