+GPU INFERENCE  INSTANCE
+
+If there are Chinese comments in the code，please add at the beginning：
+#!/usr/bin/python
+#coding=utf-8
+Due to the adaptability of a100, please use the recommended image of the
+platform with cuda 11.Then adjust the code and submit the image.
+The image of this example is: dockerhub.pcl.ac.cn:5000/user-images/openi:cuda111_python37_pytorch191
+In the environment, the uploaded dataset will be automatically placed in the /dataset directory.
+if MnistDataset_torch.zip is selected,Then the dataset directory is /dataset/test;
+
+The model file selected  is in /model  directory.
+The result download path is under /result . and the Qizhi platform will provide file downloads under the /result directory.
+
+本例中的镜像是dockerhub.pcl.ac.cn:5000/user-images/openi:cuda111_python37_pytorch191
+选择的数据集被放置在/dataset目录
+选择的模型文件放置在/model目录
+输出结果路径是/result目录
+
+！！！注意：目前推理的资源环境不支持联网，所以镜像无法使用公网镜像，镜像必须先提交到启智平台;推理的数据集也需要先上传到启智平台
