title: Using Keras/sklearn with CalibratedClassifierCV from sklearn.calibration
body: <p>Is it possible to use Keras model objects with CalibratedClassifierCV from sklearn.calibration?  Or is there another way to performa isotonic regression in sklearn/other python packages without having to pass it a model object.</p>
  
  <p>I tried using the sklearn wrapper for Keras, but it didn't work.  <a href="http://scikit-learn.org/stable/modules/generated/sklearn.calibration.CalibratedClassifierCV.html#sklearn.calibration.CalibratedClassifierCV" rel="noreferrer">Here is the doc for the CalibratedClassifierCV class</a>.</p>
