Running the Week 3 notebook on google colab (after previously encountering #33), I see

---------------------------------------------------------------------------

ImportError: cannot import name 'logsumexp'

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

Upgraded Gensim by adding a code cell with

! pip install -U gensim
