missing getColIntegrality function in Python interface (actually pyi file)

[BrannonKing]

I can't find any mechanism to query the type given to a variable when the variable was constructed. I'm using the Python interface. Is there a function for this already? getColIntegrality seems to exist at the C level, but it doesn't exist in the Python wrapper.

Which version of HiGHS are you using?

According to https://github.com/ERGO-Code/HiGHS/releases, we added getColIntegrality to highspy in v1.8.1 (Nov 2024)

Looking deeper, the problem is not with the missing function. (I'm running latest release.) I's just that Pylance is using a stub file that doesn't have it, so it reports it as missing. Do you regenerate and publish pyi stub files with each release? I'm looking at the checked-in file highs/highspy/_core/init.pyi and the function is missing there. PyBind11 should generate new pyi files on command. I don't know if your pyi file is auto-generated or manually edited, but it's definitely out of date. It's also missing the advanced tableau functions.

I confirmed that rerunning (the latest) pybind11-stubgen on (the latest) _core file produces much better pyi files -- that actually match the current release. Attached:
_core.zip

I did get these errors when running it:

pybind11_stubgen - [  ERROR] In _core._Highs.setCallback : Can't find/import 'HighsCallbackOutput'
pybind11_stubgen - [  ERROR] In _core._Highs.setCallback : Can't find/import 'HighsCallbackInput'
pybind11_stubgen - [  ERROR] In _core._Highs.startCallback : Can't find/import 'HighsCallbackType'

Thank you for spotting this, it sounds like something we may have to update in the build!
