docstr: Evaluate the best model for the given data.
  
  # Arguments
      x: String, numpy.ndarray, pandas.DataFrame or tensorflow.Dataset.
          Testing data x. If the data is from a csv file, it should be a
          string specifying the path of the csv file of the testing data.
      y: String, numpy.ndarray, or tensorflow.Dataset. Testing data y.
          If the data is from a csv file, it should be a string
          corresponding to the label column.
      **kwargs: Any arguments supported by keras.Model.evaluate.
  
  # Returns
      Scalar test loss (if the model has a single output and no metrics)
      or list of scalars (if the model has multiple outputs and/or
      metrics). The attribute model.metrics_names will give you the
      display labels for the scalar outputs.
