## data = fnames.map(lambda x: tf.py_function(process_path, [x], [tf.string]))

Next error:

images = ds.map(lambda x: tf.py_function(load_images, [x], [tf.string]),
                num_parallel_calls = tf.data.AUTOTUNE)
#> TypeError: Tensors in list passed to 'input' of 'EagerPyFunc' Op have types [<NOT
