I'm trying to do topic modeling with Gensim and Mallet (link). When I locate the mallet_path and then try to assign it to gensim, I get the error subprocess.CalledProcessError : returned non-zero exit status 1

And I get prompted to update Java (which I have done).

Any hints on how to solve it? 

mallet_path = '/Users/username/mallet-2.0.8/bin/mallet'

ldamallet = gensim.models.wrappers.LdaMallet(mallet_path, corpus=corpus, num_topics=20, id2word=id2word)
Traceback (most recent call last):

In bin directory, open the mallet file with a text editor then increase the MEMORY limit. It worked for me.
