I am running the code on cityscapes dataset which has image, labels but not weights. I am passing a list of ones as argument to weight list in read_file function. But in this line of train_batch function, train_data = tf.data.Dataset.from_tensor_slices((image_list, label_list, weight_list)), I get this as output_shapes:
(TensorShape([Dimension(1), Dimension(None), Dimension(None), Dimension(None)]), TensorShape([Dimension(1), Dimension(None), Dimension(None), Dimension(None)]), TensorShape([Dimension(1), Dimension(None), Dimension(None), Dimension(None)]))

Can you suggest why this is happening ?
