How to view images in directory iterator object tensorflow-CodePudding

i created a test dataset using ImageDataGenerator class :

imgs=tf.keras.preprocessing.image.ImageDataGenerator(preprocessing_function=tf.keras.applications.vgg16.preprocess_input).flow_from_directory(r"C:\Users\Abhimanyu\Pictures\Camera Roll",target_size=(224,224),classes=["Class 1","Class 2"])

but i want to view the images in imgs (directory iterator object) because they're shuffled

i tried to view them using matplotlib but i got TypeError

temp=next(imgs)
plt.imshow(temp[0])

>>> TypeError: Invalid shape (12, 224, 224, 3) for image data

any help would be greatly appreciated

CodePudding user response：

Your image folders probably have the wrong structure or you are forgetting that you have a tuple of data (images, labels). Anyway, this works with a default batch size of 32:

import tensorflow as tf
import matplotlib.pyplot as plt

flowers = tf.keras.utils.get_file(
    'flower_photos',
    'https://storage.googleapis.com/download.tensorflow.org/example_images/flower_photos.tgz',
    untar=True)
imgs = tf.keras.preprocessing.image.ImageDataGenerator(rescale=1./255).flow_from_directory(flowers, shuffle=True)

images, _ = next(imgs)
plt.imshow(images[0]) # display first image from batch
