TypeError: unsupported operand type(s) for +: 'int' and 'str' #21
Description
I see the following error when running ch04/blei_lda.py
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)

37 for ti in range(model.num_topics):

TypeError: unsupported operand type(s) for +: 'int' and 'str'
I think, since the frequency, f, and word, w, are the opposite on words, did you want to write w, f in words instead, as in the following?
39 tf = sum(f for w, f in words)
40 with open('topics.txt', 'w') as output:
41 output.write('\n'.join('{}:{}'.format(w, int(1000. * f / tf)) for w, f in words))
