TensorFlow giving error: Input is empty

Hello, I am trying to run the resnet model on custom images (transfer learning).

My directory tree looks like this:

train

class1

image1

image2

….

class2

image1

image2

…

val

class1

image1

image2

….

class2

image1

image2

…

And I created the tensorflow datasets like this:

train_ds = tf.keras.preprocessing.image_dataset_from_directory( “train”, labels=’inferred’, label_mode=’int’, image_size=(img_height, img_width), batch_size=batch_size)

val_ds = tf.keras.preprocessing.image_dataset_from_directory( “val”, labels=’inferred’, label_mode=’int’, image_size=(img_height, img_width), batch_size=batch_size)

Then I try to display the images for reference, running:

import matplotlib.pyplot as plt

class_names = val_ds.class_names

plt.figure(figsize=(10, 10)) for images, labels in val_ds.take(1): for i in range(30): ax = plt.subplot(5, 7, i + 1) plt.imshow(images[i].numpy().astype(“uint8”)) plt.title(class_names[labels[i]]) plt.axis(“off”)

But with val_ds, I get the error “Input is empty”, while with train_ds it actually shows the images. Anyone knows a possible reason why behind it? The dataset I am using is here – https://github.com/xuequanlu/I-Nema – and I have converted all the .tif images to .jpg.

Thanks in advance!
