[Wei-1]

A tested process to directly run ppxgboost with 1 multi-class dataset and 1 binary-class dataset without manually preparing data by running it directly in SageMaker. However, note that ppxgboost is using OPE (Order Preserving Encryption) which is a kind of PHE (Partially Homomorphic Encryption), which is a long way from FHE (Fully Homomorphic Encryption). But for XGBoost OPE is enough for the algorithm to work 100% correctly after encryption, so we can rely on OPE to keep the great performance.
