 Export MindIR
 
+Before exporting, you need to modify the parameter in the configuration — checkpoint_file_path and batch_ Size . checkpoint_ file_ Path is the CKPT file path, batch_ Size is set to 1.
+
 ```shell
-python export.py --checkpoint_file_path [CKPT_PATH] --file_name [FILE_NAME] --file_format [FILE_FORMAT]
+python export.py --config_path=[CONFIG_PATH]
 ```
 
 The checkpoint_file_path parameter is required,
 `EXPORT_FORMAT` should be in ["AIR", "MINDIR"]
 
 Before performing inference, the MINDIR file must be exported by export script on the 910 environment.
-Current batch_size can only be set to 1.
 
 ```shell
 # Ascend310 inference
-bash run_infer_310.sh [MINDIR_PATH] [DATA_PATH] [DEVICE_ID]
+bash run_infer_310.sh [NETWORK] [MINDIR_PATH] [DEVICE_ID] [NEED_PREPROCESS]
 ```
 
 `DEVICE_ID` is optional, default value is 0.

 导出mindir模型
 
+在执行导出前需要修改配置文件中的checkpoint_file_path和batch_size参数。checkpoint_file_path为ckpt文件路径，batch_size设置为1。
+
 ```shell
-python export.py --checkpoint_file_path [CKPT_PATH] --file_name [FILE_NAME] --file_format [FILE_FORMAT]
+python export.py --config_path=[CONFIG_PATH]
 ```
 
-参数`checkpoint_file_path` 是必需的，`EXPORT_FORMAT` 必须在 ["AIR", "MINDIR"]中进行选择。
-
 在执行推理前，MINDIR文件必须在910上通过export.py文件导出。
-目前仅可处理batch_Size为1。
 
 ```shell
 # Ascend310 推理
-bash run_infer_310.sh [MINDIR_PATH] [DATA_PATH] [DEVICE_ID]
+bash run_infer_310.sh [NETWORK] [MINDIR_PATH] [DEVICE_ID] [NEED_PREPROCESS]
 ```
 
 `DEVICE_ID` 可选，默认值为 0。
