Before Change

        return symmetric[..., tril_mask]
    scaling = np.ones(symmetric.shape[-2:])
    np.fill_diagonal(scaling, sqrt(2.))
    tril_mask = np.tril(np.ones(symmetric.shape[-2:])).astype(np.bool)
    return symmetric[..., tril_mask] / scaling[tril_mask]


def sym_matrix_to_vec(symmetric, discard_diagonal=False):
    Return the flattened lower triangular part of an array.

After Change

        (..., n_features * (n_features + 1) / 2) if discard_diagonal is False and
        (..., (n_features - 1) * n_features / 2) otherwise.
    
    return sym_matrix_to_vec(symmetric=symmetric, discard_diagonal=discard_diagonal)


def sym_matrix_to_vec(symmetric, discard_diagonal=False):
    Return the flattened lower triangular part of an array.
