title: AttributeError: 'Namespace' object has no attribute 'epochs_per_eval'
body: <p>I'm trying to run tensorflow wide_deep training model using latest docker model. I have mounted the official model to the docker image</p>
  
  <p><code>docker run -it -p 8888:8888 --mount type=bind,src="$(pwd)",target=/notebooks/model tensorflow/tensorflow</code></p>
  
  <p>As mentioned in the doc, I have added the model directory to the python path.</p>
  
  <p>Then I downloaded the dataset using <code>python download_data.py</code></p>
  
  <p>After down, when I run <code>python wide_deep.py</code> it throws this error</p>
  
  <pre><code>/usr/local/lib/python2.7/dist-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
