Gensim dependecies

[Liron Bilya]

Hi,

I have a question about the setup of gensim.

when I try to install the package with a specific version (in my case gensim==4.1.2) it looks like the Numpy dependency is trying to install it's latest version (currently 1.22.3)
This make a problem in a case I am trying to install the gensim==4.1.2 with python 3.7 but the Numpy package requires python 3.8 or higher.

I installed Numpy 1.21.4 but it's not enough, the package still trying to install the latest version.

I also tried to install the package without it's dependencies, but it didn't work.

I would like to know if it's suppose to be like that?

Python packages usually install the specific version of the required dependency to avoid this kind of errors.

Thanks :) 

Here is the traceback of the error:
