([key_columns, ...])Returns the SQL code needed to deploy the inverse model.
deploySQL
([X, key_columns, exclude_columns])Returns the SQL code needed to deploy the model.
does_model_exists
(name[, raise_error, ...])Checks whether the model is stored in the Vertica database.
drop
()Drops the model from the Vertica database.
export_models
(name, path[, kind])Exports machine learning models.
