 3. 使用方法
 
    安装成功后，您就可以使用本项目的 Python 接口进行编码并运行。具体使用方式可以参考项目样例代码 example/Resnet/resnet.py 以及用户使用手册
 
-## Docker
-
-本项目也提供了 Docker 的环境，您可以使用 `make docker-build` 或 `make docker-build CUDA=ON` 命令启动并编译 Dockerfile，您可以通过添加编译选项或者修改 Makefile 变量修改 docker image 名称或者所选的 Dockerfile 文件。
- 
-由于在拉取 github repo 时需要将 ssh key 加入到 github profile 中，因此暂时注释掉拉取 repo 并编译项目的过程，由用户在进入 docker 后自己维护 ssh key（将 host 中的 ssh key 复制到 docker 中可能会遇到环境不一致的问题）。
-
-```shell
-# Build docker container.
-make docker-build
-# Run docker image.
-make docker-run
-# Execute docker image.
-make docker-exec
-```
-
-如果需要编译 CUDA 版，请使用如下命令：
-```shell
-# Build docker container.
-make docker-build CUDA=ON
-# Run docker image.
-make docker-run CUDA=ON
-```

-## Description
-
-This is a doc to tell you how to run paddle*.py in your machine. If your model run on other machines except Nvidia, you may need to make some change.
-
-## What do we do in paddle*.py files?
-
-1. Train model and evalute model with Cifar10 dataset
-
-2. Export paddle model to onnx model
-
-3. Load onnx model, infer with InfiniTensor and calculate the inference accuracy
-
-## Command
-
-1. Go to `/examples/python` folder 
-
-2. Run the following command
-   
-   1. ```
-      python paddle_resnet.py
-      python paddle_densenet.py
-      python paddle_inception.py
-      ```
-
-## What should I do if I use other device(MLU, XPU, NPU)?
-
-You need to change this code:
-
-```
-paddle.device.set_device("gpu") # Change gpu to mlu, xpu or npu
-```
