\brief Get number of predictions. \param handle Handle of booster \param num_row Number of rows \param predict_type What should be predicted

• C_API_PREDICT_NORMAL: normal prediction, with transform (if needed);
• C_API_PREDICT_RAW_SCORE: raw score;
• C_API_PREDICT_LEAF_INDEX: leaf index;
• C_API_PREDICT_CONTRIB: feature contributions (SHAP values) \param start_iteration Start index of the iteration to predict \param num_iteration Number of iterations for prediction, <= 0 means no limit \param[out] out_len Length of prediction \return 0 when succeed, -1 when failure happens
