Error implementing gensim.LdaMallet

Question

I followed the instructions at this link (" http://radimrehurek.com/2014/03/tutorial-on-mallet-in-python/ "), however I encountered an error when I tried to train the model:

    model = models.LdaMallet(mallet_path, corpus, num_topics =10, id2word = corpus.dictionary)
    IOError: [Errno 2] No such file or directory: 'c:\\users\\brlu\\appdata\\local\\temp\\c6a13a_state.mallet.gz'

Please share your thoughts.

Thank.

Answer 1

This can happen for two reasons: 1. You have a place in the path of your hammer. 2. There is no environment variable MALLET_HOME.

Answer 2

• Make sure the file is running from the command line .
• "c:\users\brlu\appdata\local\temp \...", , , . .

Answer 3

• import tempfile
• < > tempfile.tempdir = 'some_other_non_system_temp_directory'

Answer 4

gensim + MALLET Windows:

• , MALLET_HOME

• mallet_path Python

  mallet_path = 'c:\\mallet-2.0.7\\bin\\mallet'
  LDA_model = gensim.models.LdaMallet(mallet_path, ...
  

• , 142 Python\Lib\site-packages\gensim\models\ldamallet.py: change --token-regex '\S+' --token-regex \"\S+\"
