+
+## Inference Process
+
+### Usage
+
+Before performing inference, the model file must be exported by export script on the Ascend910 environment.
+
+```shell
+# Ascend310 inference
+sh run_infer_310.sh [MINDIR_PATH] [DATA_PATH] [ANN_FILE] [DEVICE_ID]
+```
+
+-NOTE:Ascend310 inference use Imagenet dataset . The label of the image is the number of folder which is started from 0 after sorting.
+
+### result
+
+Inference result is saved in current path, you can find result like this in acc.log file.
+
+```python
+accuracy:80.044
