SciPy 1.9.2 for Windows does not contain msvcp140.dll

See original GitHub issue

SciPy 1.9.1 contained msvcp140.dll while 1.9.2 does not. For scikit-learn, the removal of msvcp140.dll is causing build issue because scikit-learn depended on the DLL from SciPy: https://github.com/scikit-learn/scikit-learn/issues/24612.

Coming from https://github.com/scipy/oldest-supported-numpy/issues/45 and https://github.com/scipy/scipy/pull/16842, it looks like SciPy does not need to vendor msvcp140.dll anymore. Was the removal of msvcp140.dll intentional?

It may be worth sklearn adding a CI entry for testing against the nightly builds of scipy (pippable from https://anaconda.org/scipy-wheels-nightly/scipy/files) to anticipate issues like this.

https://github.com/scikit-learn/scikit-learn/pull/24446 adds scipy nightly builds to the searchable pip indexes.

Scikit-learn 1.1.2 is vendoring the necessary DLL, so I’ll close this. Thanks for the discussion and helping solve this, everyone!
