title: TypeError: 'Keyword argument not understood:', 'padding'
body: <p>I am trying to implement the following python code, but I get the following error. Could anyone help me?</p>
  
  <pre><code>from keras.models import Sequential
  from keras.constraints import maxnorm
  from keras.layers.convolutional import Convolution2D
  
  # Create the model
  model = Sequential()
  model.add(Convolution2D(32, 3, 3, input_shape=(3, 32, 32), activation='relu', padding='same', kernel_constraint=maxnorm(3)))
  </code></pre>
  
  <p>The error I get:</p>
