Hey @bopengiowa, to filter the dataset based on class labels we need to return the labels along with the image (as tuples) in the parse_tfrecord() function. Once that is done, we could filter the required classes using the filter method of tf.data.Dataset. Finally we could drop the labels to obtain just the images, like so: TensorFlow Datasets TensorFlow Datasets is a collection of datasets ready to use, with TensorFlow or other Python ML frameworks, such as Jax. All datasets are exposed as tf.data.Datasets , enabling easy-to-use and high-performance input pipelines. To get started see the guide and our list of datasets . How to make tf.data.Dataset return all of the elements in one call? We need to pass all the members of the dataset batched into a single element. This can be used to get features as a tensor-array, or features and labels as a tuple or dictionary (of tensor-arrays) depending upon how the original dataset was created.
