I am trying to install the python package gensim. I installed scipy, smart_open and numpy, and ran pip install gensim.
the installation failed in the preparing metadata stage and a behemoth 954 lines of output were printed.
I'm not sure where is the actual error in it. cntl-f-ing for the word "error" brings
../numpy/core/src/npysort/binsearch.cpp(338): error C2131: expression did not evaluate to a constant
and right at the end there's this block of error-message-y looking text

but this is complete gibberish to me.
I tried googling some of the lines but nothing came up. adding flags such as -U or --upgrade that i've seen used online didn't seem to help either.
I also encounted this answer about a similarly long pip error. but it's for a different package and on Mac so I doubt it's relevant.
frankly, I'm out of Ideas since I can't figure what the error even is.
From your error messages, you seem to be using Python 3.13. But the stable release of gensim (i.e. 4.3.3) currently has Python 3.8 - 3.12 wheels for all major platforms. There's no support yet for Python 3.13. You can downgrade to Python 3.12 to install this package.
