I upgraded from 1.21 to 1.23.3 recently and got a variety of mypy issues. I seem to have resolved all of them, but I occasionally still see this show up:
.venv/lib/python3.10/site-packages/numpy/_typing/_array_like.py:153: error: Type argument "_UnknownType" of "dtype" must be a subtype of "generic" [type-var]
On mypy 0.981 this is not 100% repro and if I restart dmypy it goes away... until it comes back. I just now upgraded to mypy 0.982 and didn't get it on one run, at least not right away. Maybe this was some kind of mypy issue, but time will tell.
I haven't seen exactly this error getting posted anywhere. I know this is a fairly recent change and it looks like there's a lot of type hinting work going on (excellent work! I love it, thank you numpy devs!).
Anyone else got any insight on what's going on here? Is this a known issue? Is this a mypy issue?
Thanks everyone.
I'd be very curious to know if 0.982 fixes things. I know that using python 3.10.7 causes problems for mypy < 0.981.

Sadly, it does not seem to resolve the problem. I've run into the issue with mypy 0.982 several times today. I am running python 3.10.7. I've posted to the mypy gitter as well in case it's an issue on their end. I guess I should add that I haven't seen it running mypy, only running dmypy. That and the fact that it's not 100% repro does make it seem like a mypy issue. I appreciate the attention. --Nick
