title: Unexpected keyword argument 'ragged' in Keras
body: <p>Trying to run a trained keras model with the following python code:</p>
  
  <pre class="lang-py prettyprint-override"><code>from keras.preprocessing.image import img_to_array

  model = load_model(MODEL_PATH)
  
  
  print("[info] starting vid stream..")
  vs = VideoStream(usePiCamera=True).start()
  time.sleep(2.0)
  
  while True:
      frame = vs.Read()
      frame = imutils.resize(frame, width=400)
  
      image = cv2.resize(frame, (28, 28))
      image = image.astype("float") / 255.0
      image = img_to_array(image)
      image = np.expand_dims(image, axis=0)
      (fuel, redBall, whiteBall, none) = model.predict(image)[0]
      label = "none"
      proba = none
  
      if fuel &gt; none and fuel &gt; redBall and fuel &gt; whiteBall:
          label = "Fuel"
          proba = fuel
      elif redBall &gt; none and redBall &gt; fuel and redBall &gt; whiteBall:

  print("[info] cleaning up..")
  cv2.destroyAllWindows()
  vs.stop()
  </code></pre>
  
  <p>When I run it with python3, I get the following error:
  <code>TypeError: __init__() got an unexpected keyword argument 'ragged'</code></p>
  
  <p>What's causing the error, and how do I get around it? </p>
  
  <p>Versions:
  Keras v2.3.1
  tensorflow v1.13.1</p>
  
  <p>Edit to add:</p>
