Importing Gensim gensim.models.phrases import phraser fails with "ImportError: cannot import name 'Type'"

Question

I am using Python version 3.5 in a virtual environment and when trying to import the below command i am getting "ImportError: cannot import name 'Type'"

from gensim.models.phrases import Phraser

I have uninstalled all other packages and just installed gensim and still it fails. Any suggestions would be of great help

Answer 1

While you've triggered this error via from gensim.models.phrases import Phraser, the error stack indicates the line of code triggering the error is deep within the scipy package.

Specifically, it seems like gensim's attempt to merely import scipy.sparse is what leads to the error. So, it'd be useful to check if you can also trigger the error with import scipy.sparse – and if so, you have a recipe for the error that doesn't involve gensim at all, and might be worth asking as a scipy question (here on StackOverflow or in some scipy forum).

You should check what scipy and numpy versions are installed in your environment, and whether they still support Python 3.5. As Python 3.5 is barely 6 months away from its "end-of-life", when not even urgent security issues will receive fixes, you may wish to try a later Python, which might also resolve this issue. (I believe there have been a number of changes around Type-related features after Python 3.5.)
