Assuming the next 0.21 release happens around or after April 2019, the oldest Ubuntu LTS at that point will be 16.04 LTS, which includes,

  • numpy 1.11.0
  • scipy 0.17.0

(checked in a Docker image, not sure where to find the official information)

so we could probably make these our minimum requirements for 0.21.

Making so would for instance allow to implement #11638

Even assuming there is agreement on this subject, we should probably wait for 0.20.1, at least, before doing anything about it. Eventually this would involve,

  • adjusting versions of dependencies in docs and CI
  • removing the utils.fixes that are no longer needed.

I would also be in favor of bumping dependencies for scikit-learn 0.21 to those matching ubuntu 16.04 LTS so as to be able to implement what is described in #11638.

+1 on bumping and +1 on waiting for 0.20.1

From #12718
We should also consider the version of matplotlib and scikit-image
It's 1.5.1 for matplotlib (https://packages.ubuntu.com/xenial/python3-matplotlib) and 0.10.1 for scikit-image (https://packages.ubuntu.com/xenial/python3-skimage).
