My program is a feature extraction for an image processing program, we are loading the model and extracting features from each image.

  • We load the image from file
  • convert the pixels of image to numpy array
  • extract features
  • store features
  • save to file(pkl)

This is the code snippet.

from os import listdir
from pickle import dump
from keras.applications.inception_v3 import InceptionV3
from keras.preprocessing.image import load_img
from keras.preprocessing.image import img_to_array
from keras.applications.inception_v3 import preprocess_input
from keras.models import Model
import string
from timeit import default_timer as timer
from PIL import Image
import sys


for name in listdir(directory):
    # load an image from file
    filename = directory + '/' + name
    image = load_img(filename, target_size=(230,230))
    # convert the image pixels to a numpy array
    image = img_to_array(image)
    # reshape data for the model
    image = image.reshape((1, image.shape[0], image.shape[1], image.shape[2]))
    # prepare the image for the VGG model
    image = preprocess_input(image)
    # get features
    feature = model.predict(image, verbose=0)
    # get image id
    image_id = name.split('.')[0]
    # store feature
    features[image_id] = feature
    #print('>%s' % name)
return features

It gives me this error

I've installed pillow and imported it into the program but it still gives me the same error.

  • Can you check in each step if the file path you give actually exists ? – Frodon Nov 30 '20 at 18:43

    Also, make sure you have installed Pillow not PIL. Check this answer for more info: https://stackoverflow.com/a/41688942/6025629 – Mike Xydas Nov 30 '20 at 18:59

    @Likith R, Did you install `pillow` ? PIL is part of pillow. Install it as `pip install pillow`. Thanks! –  Dec 02 '20 at 14:28

Do "" pip install Image"" that will resolve your error, don't forget to uninstall PIL first
