For 1.0.0 it works, but as you see in https://github.com/RaRe-Technologies/gensim/blob/develop/setup.py#L290 our minimal version is 0.18.1, in this version, this import will be failed.
Import must work for any scipy >=0.18.1

Problem
I noticed that when training LDA model with the latest version of scipy I get a deprecation warning.
Reason
I dug into the problem and found that scipy 1.0.0 has been released recently.
https://scipy.github.io/devdocs/release.1.0.0.html
In the release they deprecated a number of functions from
scipy.misc, andlogsumexpis one of them. The link below is the corresponding commit.scipy/scipy#7246
Solution
I fixed the warning by making
logsumexpto be imported fromscipy.special, as they recommend.Also I checked that, except in LdaModel,
logsumexpis not used in any other places in gensim .
