Ping @mpenkov can we still reproduce this?

@HaukeT @aschoenauer-sebag the `topic_coherence` is a contributed module and its quality may be iffy. If you're able to fix the issue and open a clean clear PR that'd be great.

@kdubovikov What is the full traceback? I wonder if the `dictionary` in the code you show is allowed to be a plain `dict`, or must be `gensim.corpora.Dictionary`.

Thanks for reporting. That's weird – my understanding was that upgrading numpy should help. Related to #3095 and https://github.com/numpy/numpy/pull/16938. @mpenkov could you have a look please? This Numpy's C API...

Oh crap, I just submitted the Numpy ticket :)

I think so. @norbertgieruc how did you install Gensim? Was it a standard `pip install` from PyPI? Because I see some `Anaconda3` in your stack trace above. I'm not sure...

@llunn it's possible the issue with HDBScan is a separate one. Do they use `oldest-numpy-version`? Probably best to open a ticket at HDBScan, or chime in at https://github.com/numpy/numpy/issues/18709, so the...

Seems fixed now with Gensim 4.0.1. @llunn I'd recommend you urge your dependencies (top2vec etc) to upgrade using the [Gensim 4 Migration Guide](https://github.com/RaRe-Technologies/gensim/wiki/Migrating-from-Gensim-3.x-to-4). Because Gensim 4 is miles ahead of...

Hm. Maybe something to do with the fact we don't distribute Python 3.9 wheels yet? Although I don't see how that could affect whether you use `requirements.txt` or not. Some...
