Per my other message: you shouldn't have to pre-install a specific version - you can go with whatever `numpy` (& `scipy`) that 'pip' itself pulls in to match the Gensim install's specifications.
In my most recent test, those seemed to be `numpy-1.26.4 scipy-1.13.1` – but if other maintenance micro releases come out, & `pip` installs them in accordance with the Gensim stated dependencies avoiding more advanced versions, those should be fine too.
On environments where `numpy` 2+ is already installed, that involves a downgrade - as Gensim hasn't yet been updated to work with `numpy` 2+ & it's not yet clear when such changes might be possible. As far as I know, no one has scoped the effort required or scheduled the work – see <
