@hushell @vigsterkr Initially I tried to add `m_factors_table` and `m_factors_scope` parameters both of them are of type `SGVector<>*` using `SG_ADD`. The unit tests gave error (`SGObject.clone_equals_UAIFile`) and they cannot be added until https://github.com/shogun-toolbox/shogun/issues/1972 has been resolved. Any suggestions ?
