  + """A placeholder method for backward compatibility.
  +
  + The preprocessing logic has been included in the efficientnet model
  + implementation. Users are no longer required to call this method to normalize
  + the input data. This method does nothing and only kept as a placeholder to
  + align the API surface between old and new version of model.
  +
  + Args:
  + x: A floating point `numpy.array` or a `tf.Tensor`.
  + data_format: Optional data format of the image tensor/array. Defaults to
  + None, in which case the global setting
  + `tf.keras.backend.image_data_format()` is used (unless you changed it,
  + it defaults to "channels_last").{mode}
  +
  + Returns:
  + Unchanged `numpy.array` or `tf.Tensor`.
