在Java中,执行Shell命令通常使用Runtime类的exec()方法。该方法创建一个子进程执行Shell命令,并返回一个Process对象,通过该对象可以获取Shell命令的执行结果。 importjava.io.BufferedReader;importjava.io.IOException;importjava.io.InputStreamReader;publicclassShellCommandExecutor{publicstaticStringexecuteCommand(Stringco...
java调用runTime 执行shell 命令 java的runtime 一、Runtime 我们来看下文档中对Runtime的说明: 每一个java程序都有一个属于Runtime类的实例,它允许程序连接到程序运行环境。 当前runtime可以用getRuntime()方法获得。 程序无法创建自己的此类实例。 public class Test {...

很多机器学习框架都会采用如下套路:shell脚本(可选),python端 和 C++端。 Shell脚本是启动运行的入口,负责解析参数,确认并且调用训练程序; Python是用户的接口,引入了C++库,封装了API,负责运行时和底层C++交互; C++实现底层训练逻辑; 所以我们先看看 hordovodrun 脚本。
