Default: "STAND_ALONE". - STAND_ALONE: Only one processor working. - DATA_PARALLEL: Distributing the data across different processors. - HYBRID_PARALLEL: Achieving data parallelism and model parallelism manually. - SEMI_AUTO_PARALLEL: Achieving data parallelism and model parallelism by setting parallel strategies. - AUTO_PARALLEL: Achieving parallelism automatically. MODE_LIST: The list for all supported parallel modes.
