Can't run usage/dev.py

[wong2]

Hi, I removed the comment before corpus.lda(100, 30, 2.5, 0.1) in usage/dev.py, then run it, and I got this error:

Traceback (most recent call last):
  File "dev.py", line 19, in <module>
    corpus.lda(100, 30, 2.5, 0.1)
  File "/home/wong2/codes/bi/lda/lda.py", line 145, in lda
    new_topic_index = np.random.multinomial(1, np.random.dirichlet(topic_distribution)).argmax()

To @wong2 : You may go to see my forked repo: https://github.com/hitalex/lda-with-gibbs I have done some corrections.

@hitalex Thanks, though I no longer need to play with LDA.

It is just a toy example of Gibbs sampling after all.
