title: How to get more detailed error information numpy for "RuntimeWarning: invalid value encountered in multiply" error
body: <p>Is there a way to get more detailed from numpy for the error message</p>
  
  <p>"RuntimeWarning: invalid value encountered in multiply"</p>
  
  <p>It comes from a certain line in the code where I"m doing a number of array operations.  Can I get numpy to report:</p>
  
  <p>(1) More information on the invalid value (inf? nan?)</p>
  
  <p>(2) The array entry that is causing the problem?</p>
  
  <p>Of course I can inspect the array myself but it would be nice if numpy could just tell me what  and where the problem is.</p>
