[Debian-med-packaging] Bug#959138: numpy breaks nipy autopkgtest: No module named 'numpy.testing.decorators'

Dear maintainer(s),

With a recent upload of numpy the autopkgtest of nipy fails in testing
when that autopkgtest is run with the binary packages of numpy from
unstable. It passes when run with only packages from testing. In tabular
form:

                       pass            fail
numpy                  from testing    1:1.18.3-1
nipy                   from testing    0.4.2-3
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of numpy to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?
