def image_reader():      # filename queue     filename_queue = tf.train.string_input_producer(     tf.train.match_filenames_once(data_path + "/*.jpg"))      # read entire image file required s     image_reader = tf.wholefilereader()      # read whole file queue, first returned value in   tuple filename     key, image_file = image_reader.read(filename_queue)      # decode image jpeg file give image tensor      image = tf.image.decode_jpeg(image_file)     return image, key
