scipy is held to 1.2.x because we still want to support Python2 for the upcoming Sage 9.1, and further versions of scipy are Python3-only.

Now, you can do, from a terminal:

sage -pip install --upgrade scipy

EDIT the non-lazy version is to use the Sage package manager:

download https://github.com/scipy/scipy/releas... within sage's upstream/ directory
edit /build/pkgs/scipy/package-version.txt so that it contains the string 1.4.1
run sage --package fix-checksum to fix the checksums
run sage -i scipy to install the package

At your own risks ;)

I did this, but sage still gives (and I checked if it was using the newer features of simpy, which is not):

sage: from sage.misc.package import list_packages, installed_packages
sage: installed_packages()['scipy']
'1.2.0'

although:

$ sage -pip show scipy

The first comment is an artifact of Sage package management, which the proposed simplest method skipped. Could you please provide code that shows that latest features are not taken into account.

sorry, I should have edited my comment, I hadn't restarted sage (maybe...), but it seems to work,

sage: import scipy
sage: scipy.__version__
'1.4.1'

Thanks!

OK. I was surprized !
