You need to install openblas (and lapack, if openblas does not install it).
You also need gcc, g++, and gfortran for building various components, and the suitable python-devel and python-pip packages. I further have the suitable python tkinter, six, and wheel packages installed from cygwin. I am finding that building scipy takes quite a while (a lot of long C and Fortran optimizing compilations). Above, when I say "suitable", I mean python37 (or whatever). scipy built for me under 3.7 just now, and I am starting a 3.8 build, which will require a local build of numpy, I believe, tediously longer :-) ...
