Can't import OkapiBM25Model

[lidija-jovanovska]

Problem description

I'm trying to use OkapiBM25Model. I installed the latest version of gensim, using the command pip install gensim==4.2.0 and when I try to import the model using from gensim.models.bm25model import OkapiBM25Model the file is not found. From inspecting the library in my local folder site-packages I can see that the bm25model file is not there. However, when I search for the same file on the github repo, I see that the file is there. I also checked using the previous version (4.1.2) but I got the same issue.

Steps/code/corpus to reproduce

pip install gensim==4.2.0

from gensim.models.bm25model import OkapiBM25Model

IIRC the OkapiBM25Model hasn't been released yet, it only lives in the active pre-release branch. @Witiko @mpenkov can you confirm?

[lidija-jovanovska]

Ok, that makes sense. I was checking on the default github repo which is develop. Any ideas as of when will this be released? Thanks!

[piskvorky]

@mpenkov Misha what's a good time for a sync call, to go over what we need to make a new release?

Not urgent, but let's plan ahead. Thanks.

@piskvorky Yes. Gensim has not had a release since 4.2.0 in May, whereas #3304 has only been merged in September.
