numpy install with repro testing

[Andreas Müller]

First: I like the testing repro, it looks and feels very consistent! What irritated me is the size of that installation, and identified two packages which grew strongly:

• numpy install is quite huge, because the mkl version is used, which got many binaries/dlls in the site-package directory. I propose to use the "vanilla" version, like in anaconda.

proj: in share/proj, the geoid definitions seems to be very complete ;-) May be there is a way to keep the packages small and provide the possibility to upgrade for extra functionality?

numpy upgraded to vanilla 1.20.2.

But for proj-data I don't have a good approach. All grids are required somewhere, but nobody needs them all. And one might not even need all grids of a certain area. There's no splitting upstream either (there the preferred approach is dynamic download).

Thank you jef, I red about proj and I think you are right. As long as proj doesn't have a tool or offers a kind of subpackages, there is no easy way, to split the data. I only fear, proj-data will grow on.

Since this numpy change, I have trouble using Scipy Spatial.

I revert to numpy-MKL and the error disappeared.

Fixed in python3-scipy-1.6.2-2
