title: python runtime warning debugging
body: <p>I am trying to learn Python, and I am still a novice so please bear with me. I am using the Komodo IDE environment. I currently wish to debug a a runtime warning that says:</p>
  
  <p><code>RuntimeWarning: invalid value encountered in greater &amp; (matrixCsvOutput[:,8] &gt; 30))[0] ,:]</code></p>
  
  <p>Now, I wish to set a breakpoint that would allow me to examine the composition of "matrixCsvOutput" at runtime. I expect that the value in question may be a null or a nan, and therefore fail the operation. </p>
  
  <p>My question is: how can I set the debugger to break when the runtime error occurs? Many thanks in advance!</p>
