Comment(by warren.weckesser):

 The suggested code above is not correct.  This should do it:
 {{{
 import numpy

 class ErrorSettings(object):

     def __init__(self, **kwds):
         self.new_settings = kwds

     def __enter__(self):
         self.old_settings = numpy.seterr(**self.new_settings)

     def __exit__(self, type, value, traceback):
         numpy.seterr(**self.old_settings)
 }}}
