and we silence our tests ;-) but apparently not externals checks

Ha -- poking in my eyes works at times!  Thanks Josef!

Apparently it is indeed numpy warnings so np.seterr(all="ignore") was
effective!

BUT scipy does use straight printouts of warnings, and that is what made me
believe that it was one of them:
