Error when implementing gensim.LdaMallet

Question

I was following the instructions on this link ("http://radimrehurek.com/2014/03/tutorial-on-mallet-in-python/"), however I came across 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 any thoughts you might have.

Thanks.

Have you solved this issue? I am facing the same right now – Kartheek Palepu Jun 08 '18 at 09:51 — Kartheek Palepu, Jun 08 '18 at 09:51

This can happen for two reasons: 1. You have space in your mallet path. 2. There is no MALLET_HOME environment variable.

I have the same problem as the original poster. Mallet is in `C:\Mallet` and the environment variable is `C:\Mallet\` checked from `cmd.exe` with `echo %MALLET_HOME%` Is there something I'm missing or could there be another solution? – Artturi Björk Mar 24 '15 at 21:25

In my case I forgot to import gensim's mallet wrapper. The following code resolved the error.

import os
from gensim.models.wrappers import LdaMallet

os.environ['MALLET_HOME'] = 'C:/.../mallet-2.0.8/'

A more detailed explanation can be found here: https://github.com/RaRe-Technologies/gensim/issues/2137

Make sure that mallet properly works from command-line.
Look to your folder 'c:\users\brlu\appdata\local\temp\...' if there are some files, you can deduce at which step mallet-wrapper fails. Try this step at command line.

I had similar problems with gensim + MALLET on Windows:

Make sure that MALLET_HOME is set

Escape slashes when set mallet_path in Python

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

Also, it might be useful to modify line 142 in Python\Lib\site-packages\gensim\models\ldamallet.py: change --token-regex '\S+' to --token-regex \"\S+\"

Hope it helps
