Numpy Prerelease Failure

Just had a build which failed with the numpy prerelease:

=================================== FAILURES ===================================

self = <astropy.units.tests.test_quantity_ufuncs.TestUfuncCoverage object at 0x7f53072ec2e8>

    def test_coverage(self):

        all_np_ufuncs = set([ufunc for ufunc in np.core.umath.__dict__.values()

                             if type(ufunc) == np.ufunc])

    

        from .. import quantity_helper as qh

    

        all_q_ufuncs = (qh.UNSUPPORTED_UFUNCS |

                        set(qh.UFUNC_HELPERS.keys()))

E       assert {<ufunc 'float_power'>} == set()

E         Extra items in the left set:

E         <ufunc 'float_power'>

E         Use -v to get the full diff

Maybe that’s an upstream issue but it’s more likely they added another ufunc that should be supported with quantities.

This was added very late in the development cycle. PR in progress…

@bsipocz I think the main reason why this wasn’t spotted is because numpy-dev is an allowed failure. In most cases one never looks at the CI reports if the lights are green. The PR was added a 12 days ago: https://github.com/numpy/numpy/pull/8190

@mhvk Thanks!
