numpy+mkl installing wrong version

[mohmesflir]

Gohlke has started adding vanilla wheels for numpy and trying to install using "pipwin install numpy" is choosing the vanilla wheel instead of the mkl wheel. Is there a way to request the mkl version without specifying a specific version number?

Hi, yes the local identifer (mkl, vanilla) in version string is handled automatically if you specify versions like this

pipwin download numpy=="1.19.5+vanilla"

Filter only based on version string is probably not supported by the default specifier parser. Check this PEP for more details.

pipwin download numpy=="1.19.5+vanilla" is not working as I get a

ValueError: Could not satisfy requirement numpy==1.19.5+vanilla

But this is a minor detail. At least my goal in using pipwin is to not have to manually download the proper wheel file and instead have pipwin install the latest version. However, now that Gohlke has started providing both mkl and vanilla versions of numpy, running pipwin install numpy may end up installing either the mkl or the vanilla version. At least in my testing, I cannot filter for only the mkl versions - i.e. pipwin install numpy=="mkl". Is there a way to filter a package for a specific variant without specifying the version number?

Here is the error chain that I get when running the following:
pipwin install numpy=="1.19.5+mkl"

Package numpy==1.19.5+mkl found in cache

I am using pipwin v0.5.1

You are running python 3.9 and there isn't a vanilla packaging available for NumPy for Python 3.9, only up to 3.8 here https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

hence the could not satisfy requirement

pipwin download numpy=="1.19.5+vanilla"

It would be nice if it is pipwin install numpy=="*mkl"
