It can't have been "just an update" because python-3.7 is your default
python, so you have selected it after the update.
Alternatively: Your numpy doesn't work for a longer time and you just
didn't realize until now.
numpy was built for python-3.6 and not for python3.7. Which is perfectly
fine as it is gentoos default -
base/make.defaults:PYTHON_TARGETS="python2_7 python3_6".
So why did you install python-3.7 and set it as default although your
system isn't prepared for it?
