'PrefetchDataset' object has no attribute 'class_indices'

Well I have created a model and I am trying to reach its labels and I want to create a label map for this dataset. I have created the data set in the code below

train_ds = tf.keras.utils.image_dataset_from_directory(
    data_dir,
    validation_split = 0.2,
    subset = "training",
    seed = 123,
    image_size = (img_height, img_width),
    batch_size = batch_size)

val_ds = tf.keras.utils.image_dataset_from_directory(
    data_dir,
    validation_split = 0.2,
    subset = "validation",
    seed = 123,
    image_size = (img_height, img_width),
    batch_size = batch_size)

I am trying it like this in Jupyter Notebook

train_ds.class_names

It should give an output for the class names, but it gives an error like this:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In [29], line 1
----> 1 train_ds.class_names

AttributeError: 'PrefetchDataset' object has no attribute 'class_names'

What should I do? I used the same class_names method before in the same code, it was working but now it gives an error like this. Can you help me?

Solution

  • I have used an array and give it to the labels as class names. This solved my problem.
