LDA Mallet CalledProcessError

Question

我正在尝试实现以下代码：

import os
os.environ.update({'MALLET_HOME':r'c:/mallet-2.0.8/'})

mallet_path = 'C:\\mallet-2.0.8\\bin\\mallet'
ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=bow, num_topics=20, id2word=dictionary)

但是，我一直收到这样的错误：

命令'C:\mallet-2.0.8\bin\mallet导入-文件-保存-情况-保持顺序-删除-停止词-令牌-regex "\S+“-输入C:\Users\Joshua\AppData\Local\Temp\98094d_corpus.txt -输出C:\Users\Joshua\AppData\Local\Temp\98094d_corpus.mallet‘返回非零退出状态1。

我以前能够用相同的目录在我的笔记本上执行这段代码，但是它没有在我的PC上执行(我目前正在运行python)。

有人能告诉我我做错了什么吗？

我也遇到了一个类似的错误。再次检查您是否安装了java，并且文件路径是否正在调用java。我必须编辑在mallet文件夹C:\mallet\mallet-2.0.8\bin中找到的mallet.bat文件，如下所示：

​

@echo off

rem This batch file serves as a wrapper for several
rem  MALLET command line tools.

if not "%MALLET_HOME%" == "" goto gotMalletHome

echo MALLET requires an environment variable MALLET_HOME.
goto :eof

:gotMalletHome

set MALLET_CLASSPATH=C:\mallet\mallet-2.0.8\class;C:\mallet\mallet-2.0.8\lib\mallet-deps.jar

set CMD=%1
shift

if "%CMD%"=="run" set CLASS=%1 & shift

if not "%CLASS%" == "" goto gotClass

echo Mallet 2.0 commands:

goto :eof

:gotClass

set MALLET_ARGS=

:getArg

if "%1"=="" goto run
set MALLET_ARGS=%MALLET_ARGS% %1
shift
goto getArg

:run

"C:\Program Files\Java\jdk-12\bin\java" -ea -Dfile.encoding=%MALLET_ENCODING% -classpath %MALLET_CLASSPATH% %CLASS% %MALLET_ARGS%

:eof

​

然后更改您的文件路径以反映此更改：

​

mallet_path = 'C:/mallet/mallet-2.0.8/bin/mallet.bat'

​

希望这会有所帮助:)
