Before Change

    def fit(self, hp, data):
        axis = tuple(range(len(data.shape) - 1))
        self.mean = np.mean(data,
                            axis=axis,
                            keepdims=True).flatten()
        self.std = np.std(data,

After Change

        total_sum = data.reduce(np.float64(0), sum_up) / num_instance
        self.mean = tf.reduce_mean(total_sum, axis=axis)

        total_sum_square = data.reduce(np.float64(0), sum_up_square) / num_instance
        square_mean = tf.reduce_mean(total_sum_square, axis=axis)
        self.std = tf.sqrt(square_mean - tf.square(self.mean))

    def transform(self, hp, data):
         Transform the test data, perform normalization.
