這可以從windows命令行執行：c:\mallet\bin\mallet run

我試過了

^{pr2}$

然后得到一個錯誤WindowsError: [Error 2] The system cannot find the file specified

我試過了subprocess.call(['c:/mallet/bin/mallet', 'run'])

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

我要傳給什么subprocess.call()? 在

為了完整起見，我想傳遞的完整命令是：bin\mallet run cc.mallet.topics.tui.DMRLoader texts.txt features.txt instance.mallet

我模糊的想法是這是一個預編譯的java類，我正在以某種方式調用它，但我并不真正理解我在這里做什么。在
