Yes. I'm actually pleased that the install succeeded on Window, although
you won't have good BLAS/LAPACK, just the numpy C versions of lapack_lite.
The warning/error is a bit concerning though, it would be nice to know if
it is from Python3.8 pip or numpy.

We will need to work on generating 3.8 wheels as soon as Python 3.8 is
released. I'd like to try before then, but the simplest attempt failed and
I didn't pursue it.
