R keras package Error: Python module tensorflow.contrib.keras.python.keras was not found : <p>I have <code>keras</code> installed with <code>devtools</code> from GitHub in R and TensorFlow installed in Python. </p>

<p>However when I run an example Keras command like:</p>

<pre><code>model &lt;- keras_model_sequential() 
</code></pre>

<p>I get the following:</p>

<blockquote>
