multiprocessing doesnot work properly

[abhishekkrthakur]

I have observed that multiprocessing does not work properly if the corpus is huge. Right now Im dealing with around 10k documents and setting n_jobs = 1 works fine. However, n_jobs = 4 makes Python force close. I'm working on a MacOSX Mavericks.

Hey,
Can I know what's your feature size and number of topics?
I test it on Macbook pro with OSX Maverick with 4GB ram and it works fine for me.

Here is my test setting:

1. dataset: 20 news group (same as the one I use in lda_example.py)
2. Parameters:

• n_topics = 100
• n_docs = 11k
• n_feature = 35K
• n_jobs = 4
