title: How to display progress of scipy.optimize function?
body: <p>I use <code>scipy.optimize</code> to minimize a function of 12 arguments.</p>
  
  <p>I started the optimization a while ago and still waiting for results.</p>
  
  <p>Is there a way to force <code>scipy.optimize</code> to display its progress (like how much is already done, what are the current best point)?</p>
