Hi Bas,
thank you! I checked and indeed: I was surprised to see the outdated
"data-science-types" package installed. I removed it and the amount of
mypy errors decreased dramatically. I'm so glad I asked, I already spent
way too much time at googling ;-)
Thanks again for the fast and accurate reply!
Vincent.

Hi Vincent,
Could it be that you're overriding numpy's type annotations with those
from an external stub-only package?
The functions that you mentioned have been annotated as being in the
main namespace ever since the 1.20 release;
the error message for `finfo` in particular makes me suspicious.
For reference:
```
finfo_obj = np.finfo(np.float64)
reveal_type(finfo_obj.tiny)# Revealed type is
"numpy.floating*[numpy.typing._64Bit*]"
reveal_type(finfo_obj.foo)# "finfo[floating[_64Bit]]" has no attribute "foo"
```
Regards,
Bas van Beek

Hi all,
I've got a question about numpy typing. We have our own internal
codebase that heavily depends on numpy, and we're trying to get the
number of mypy errors down. Many of the remaining mypy errors are
actually numpy false positives. I hoped that with the numpy 1.22.0
release these would be fixed, as there ought to be many typing
improvements in that version, but apparently they're not? I'm asking
here to check if this is just still a work in progress and we should be
patient, or if there's something wrong on our side...?
Some typical false positives are:
"finfo[float32]" has no attribute "tiny"
Module has no attribute "count_nonzero"
Module has no attribute "rot90"
Module has no attribute "asfortranarray"
Module has no attribute "isfinite"
Module has no attribute "any"
Module has no attribute "histogram"; maybe "histogramdd"?
Module has no attribute "bitwise_or"
Module has no attribute "bitwise_and"
Module has no attribute "indices"
Module has no attribute "pad"
versions:
python 3.8.10; numpy 1.22.0; mypy 0.930
