title: scipy error, but no exception raised
body: <p>i've encountered a usual scipy.interpolate error : </p>
  
  <pre><code>&gt;&gt;&gt; sx = interpolate.UnivariateSpline(T,X)
    File "...scipy/interpolate/fitpack2.py", line 143, in __init__
      xb=bbox[0],xe=bbox[1],s=s)
  dfitpack.error: (m&gt;k) failed for hidden m: fpcurf0:m=3
  </code></pre>
  
  <p>Is there some Python Exception attached to this error ? (i just want to intercept the exception and ignore it)</p>
  
  <p>If not, how can I do to continue running my program ?
  Thanks</p>
  
  <h2>I'm back a few hours later, to give a solution :</h2>
  
  <p>this piece of code, to catch exception and raise my own exception.:</p>
  
  <pre><code>try : 
     sx = interpolate.UnivariateSpline(X,Y)
  except : 
     raise PyGlideSplineError("%s : impossible de calculer la spline"%whoami())
  </code></pre>
  
  <p>It works !!!</p>
  
  <p>Thank you</p>
