If you encounter an error message similar to
gensim ImportError: cannot import name utils
then a likely reason is that there are conflicting copies of NumPy, SciPy, or utils. This is a common case for users of Canopy. A quick fix is as follows
pip uninstall numpy pip uninstall scipy pip uninstall utils
We then re-install gensim
pip install --upgrade gensim
Re-launch your analysis environment and you should have no problems with importing gensim. Hopefully it helps!
