 You can start training using python or shell scripts. The usage of shell scripts as follows:
 
-- Ditributed training on GPU: sh run_distribute_train_for_gpu.sh [DATA_DIR]
+- Ditributed training on GPU: sh run_standalone_train_for_gpu.sh [DEVICE_NUM] [VISIABLE_DEVICES(0,1,2,3,4,5,6,7)] [DATASET_PATH]
