Image resize with PIL Error

Question

I'm doing machine learning project and I got some trouble using Python and PIL. I downloaded some images from google and I'm trying to resize them using PIL, but i got an error, which i don't understand and i do not know what to do.

path = '.../Dataset'

for folder_name in breeds:
    for image in os.listdir(path + '/' + folder_name):
        img = Image.open(path + '/' + folder_name + '/' + image)
        new_width  = 200
        new_height = 200
        img = img.resize((new_width, new_height), Image.ANTIALIAS)
        img = img.convert("RGB")
        img.save(path + '/' + folder_name + '/' + image)

I want to load the image and then resize it so all the images I have are fixed sized (200,200). (All the images i downloaded with the crawler are at least 200x200). I was getting some strange error but after googleing it i saw that i have to convert the image to RGB. After that i try to save it. After processing like 30-40k images i got this error :

    234 
    235                         b = b + s

OSError: image file is truncated (9 bytes not processed)

Any ideas how to deal with that? Thanks!

I read the topic you suggest, but i still do not know if it solves my problem. Can i for example catch the exception i get and remove the image which causes the problem? — Zarrie, Feb 04 '18 at 18:17
Can you post the image, or an URL to the image? I'd like to reproduce the problem. — Michiel Overtoom, Feb 05 '18 at 15:02

You certainly can catch the OSError that is thrown, like this:

#!/usr/bin/env python3

from PIL import Image
import os

try:
    fn = "earthmap.tiff"
    im = Image.open(fn)
    im = im.resize(200, 200)
    im.save("eartmap-output.tiff")
except OSError:
    print(f"Error processing '{fn}', deleting...")
    os.unlink(fn)
