cannot import name 'triu' from 'scipy.linalg'

Hi, I installed gensim as mentioned in the documentation: 

pip install --upgrade gensim


problem, when I do: 

import gensim

I get:

How can I fix the error??

Thank you in advance

Scipy recently removed these functions after a fairly brief (less than 1 year) 'deprecation' warning period. The easiest workaround for now is to use scipy 1.12 rather than the very-lates: `pip install scipy==1.12`.

(The simple fix for this in Gensim has already been applied in source code and the next public release of Gensim won't require such a workaround – see issue https://github.com/piskvorky/gensim/issues/3525 )
