[Python-modules-team] Latest upgrade of Numpy breaks tests of other packages (Was: Bug#848758: python-skbio: FTBFS: Test failures)

[Andreas Tille]

[Debian Science maintainers and Debian Med packaging in CC as warning]

Hi Sandro,

it seems the recent upgrade of numpy has broken some tests in other
packages like for instance this one in python-skbio.  I wonder whether
you are either able to suggest patches to get the tests working with the
new interface of numpy again or whether it might be sensible to revert
the upgrade of python-numpy to the previous version considering that we
are quite close to the freeze.

Kind regards

        Andreas.
