WebAttributes: scale_ndarray of shape (n_features,) or None. Per feature relative scaling of the data to achieve zero mean and unit variance. Generally this is calculated using np.sqrt (var_). If a variance is zero, we can’t achieve unit variance, and the data is left as-is, giving a scaling factor of 1. scale_ is equal to None when with_std=False.
