I just though you might be doing something like this, based on a
bizarre error your log shows:
[numpy-1.16.1]
/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld:
cannot find -lblas
Normally speaking, if you use openblas from Sage, there is no -lblas
anywhere in the linking commands of Numpy, cause
Numpy configuration would try to look for blas, not find it, and do
not try to link against blas.so at all.
Have a look in logs/pkgs/numpy-1.16.1.log to see where it finds blas.
E.g. in the log on my machine I see there
Library blas was not found. Ignoring
FOUND:
libraries = ['openblas']
library_dirs = ['/home/dimpase/sage/local/lib']
language = c
define_macros = [('HAVE_CBLAS', None)]
include_dirs = ['/home/dimpase/sage/local/include']
