 ## 使用方法
 ### 1. 配置环境
 安装paddle:2.2.2 docker镜像。
 ```
-sudo nvidia-docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.2
+sudo docker pull registry.baidubce.com/paddlepaddle/paddle:2.2.2

 ```
 
 ### 2. 演示
 * 运行如下命令，完成相关资源和库的下载和服务启动。
 ```
+cd /paddle
 bash websocket_server.sh
 ```
 上面脚本完成了如下两个功能：
-1. 完成resource.tar.gz下载，解压后,会在resource中发现如下目录：
