+
+### Export MindIR
+
+```bash
+python export.py --ckpt_file [CKPT_PATH] --file_name [FILE_NAME] --file_format [FILE_FORMAT]
+```
+
+The ckpt_file parameter is required,
+`FILE_NAME` is the name of the AIR/ONNX/MINDIR file.
+`FILE_FORMAT` should be in ["AIR","ONNX", "MINDIR"]
+
+### Infer on Ascend310
+
+Before performing inference, the mindir file must be exported by `export.py` script. We only provide an example of inference using MINDIR model.
+
+```shell
+# Ascend310 inference
+bash run_infer_310.sh [MINDIR_PATH] [DATASET_NAME] [DATASET_PATH] [NEED PREPROCESS] [DEVICE_ID]
+```
+
+- DATASET_NAME can choose from ['cifar10', 'imagenet2012'].
+- NEED_PREPROCESS means weather need preprocess or not, it's value is 'y' or 'n'.
+- DEVICE_ID is optional, it can be set by environment variable device_id, otherwise the value is zero"
+- `DVPP` is mandatory, and must choose from ["DVPP", "CPU"], it's case-insensitive. SE-net only support CPU mode.
+- `DEVICE_ID` is optional, default value is 0.
+
+### Result
+
+Inference result is saved in current path, you can find result like this in acc.log file.
+
+```bash
+result: {'top_1_accuracy': 0.9449118589743589}

 In dataset.py, we set the seed inside "create_dataset" function. We also use random seed in train.py.
