这可以从windows命令行执行：c:\mallet\bin\mallet run

我试过了

^{pr2}$

然后得到一个错误WindowsError: [Error 2] The system cannot find the file specified

我试过了subprocess.call(['c:/mallet/bin/mallet', 'run'])

然后找出错误WindowsError: [Error 193] %1 is not a valid Win32 application

我要传给什么subprocess.call()? 在

为了完整起见，我想传递的完整命令是：bin\mallet run cc.mallet.topics.tui.DMRLoader texts.txt features.txt instance.mallet

我模糊的想法是这是一个预编译的java类，我正在以某种方式调用它，但我并不真正理解我在这里做什么。在

以下是文件夹bin中的两个mallet文件：
