this package only works if you need (lib)openblas, but also you want keep the package blas from [extra].

Is there a way to make this package get along with the [extra] openblas package?

Frustrating that I can't have python2-numpy and leela zero installed at the same time.

I get the following error:

I did pacman -Fs libgfortran.so.3 and installed community/gcc6-libs which seems to provide libgfortran.so.3 however had no luck compiling this library. Any help appreciated.

Build fine on my 24threads machine

This package cannot build on a single-core computer.
Change
NUM_THREADS="$(nproc)"
to
NUM_THREADS=4
or other number except 1 will make it work.

openblas-lapack or openblas can't be installed together with blas from [extra]

Or, for that matter, the "openblas-lapack" package?

What does this package do that the "openblas" package on the AUR doesn't?
