title: Error in keras - name 'Dense' is not defined
body: <p>I'm new to Deep Neural Network libraries in python. I've installed Theano &amp; keras in my windows system by following these steps(I already had anaconda):</p>
  
  <p>Install TDM GCC x64.</p>
  
  <p>Run the below code from command prompt</p>
  
  <pre><code>conda update conda
  conda update --all
  conda install mingw libpython
  pip install git+git://github.com/Theano/Theano.git
  pip install git+git://github.com/fchollet/keras.git
  </code></pre>
  
  <p>When I'm running the following code in Ipython, </p>
  
  <pre><code>import numpy as np
  import keras.models
  from keras.models import Sequential
  model = Sequential()
  model.add(Dense(32, input_shape=(784,)))
  model.add(Activation('relu'))
  </code></pre>
  
  <p>it is showing the following error:</p>
  
  <hr>
  
  <p>NameError</p>
  
  <p>Traceback (most recent call last)</p>
  
  <p>----> 1 model.add(Dense(32, input_shape=(784,)))</p>
  
  <p>NameError: name 'Dense' is not defined</p>
  
  <p><a href="http://i.stack.imgur.com/q9ZMp.png" rel="noreferrer">Here</a> is the error message screenshot.</p>
  
  <p>How come sequential was imported successfully and 'Dense' was not defined?</p>
