尝试访问Jupyter笔记本中的gensims槌时出现错误。我在笔记本所在的文件夹中有指定的文件“mallet”，但似乎无法访问它。我尝试从C驱动器路由到它，但是仍然遇到相同的错误。请帮忙 :)
import os
from gensim.models.wrappers import LdaMallet
#os.environ.update({'MALLET_HOME':r'C:/Users/new_mallet/mallet-2.0.8/'})
mallet_path = 'mallet' # update this path
ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=bow_corpus, num_topics=20, id2word=dictionary)
result = (ldamallet.show_topics(num_topics=3, num_words=10,formatted=False))
for each in result:
print (each)最佳答案
将路径更新为:
mallet_path = 'C:/mallet/mallet-2.0.8/bin/mallet.bat'并将“mallet 2.0.8”文件夹中的记事本“mallet.bat”编辑为:
@echo off
rem This batch file serves as a wrapper for several
rem MALLET command line tools.

echo MALLET requires an environment variable MALLET_HOME.

echo Mallet 2.0 commands:
echo import-dir load the contents of a directory into mallet instances (one per file)
echo import-file load a single file into mallet instances (one per line)
echo import-svmlight load a single SVMLight format data file into mallet instances (one per line)
echo info get information about Mallet instances
echo train-classifier train a classifier from Mallet data files
echo classify-dir classify data from a single file with a saved classifier
echo classify-file classify the contents of a directory with a saved classifier
echo classify-svmlight classify data from a single file in SVMLight format
echo train-topics train a topic model from Mallet data files
echo infer-topics use a trained topic model to infer topics for new documents
echo evaluate-topics estimate the probability of new documents given a trained model
echo prune remove features based on frequency or information gain
echo split divide data into testing, training, and validation portions

notepad mallet.bat

dir /OD
cd %userdir%
cd %userpath%
cd\
cd users
cd your_username
cd appdata\local\temp\2
dir /OD问题是未正确安装Java或路径(不包括Java)和槌类路径未正确定义。更多信息在这里:https://docs.oracle.com/javase/7/docs/technotes/tools/windows/classpath.html。这解决了我的错误，希望对其他人有所帮助:)
