title: Change numpy.seterr defaults?
body: <p>I'd like to change my seterr <em>defaults</em> to be either all 'warn' or all 'ignore'.  This can be done interactively by doing <code>np.seterr(all='ignore')</code>.  Is there a way to make it a system default?  There is no <code>.numpyrc</code> as far as I can tell; is there some other configuration file where these defaults can be changed?</p>
  
  <p>(I'm using numpy 1.6.1)</p>
  
  <p>EDIT: The problem was not that numpy's default settings had changed, as I had incorrectly suspected, but that another code, <code>pymc</code>, was changing things that are normally <code>ignore</code> or <code>warn</code> to <code>raise</code>, causing all sorts of undesired and unexpected crashes.</p>
