TreeliteModel class has PredictorHandle treelite_model_ member.
typedef void* PredictorHandle;
Looks like we have a memory leak issue because we do not delete treelite::Predictor to which treelite_model_ points.
treelite_model_ is not wrapped with unique_pointer. wrapping void* with unique_pointer does not work anyway - it needs actual object type such as predictor::Predict.
it is easier to just add explicit cleanup method to TreeliteModel to fix memory leak issue.
Add TreeliteModel destructor
