title: (TensorFlow on Windows) ImportError: cannot import name 'model_analyzer'
body: <p>I am attempting to train a TensorFlow model in Windows 10 using these steps: <a href="https://github.com/tensorflow/models/tree/master/attention_ocr#requirements" rel="nofollow noreferrer">https://github.com/tensorflow/models/tree/master/attention_ocr#requirements</a></p>
  
  <p>I have installed virtualenv for Windows (<a href="http://www.tylerbutler.com/2012/05/how-to-install-python-pip-and-virtualenv-on-windows-with-powershell/" rel="nofollow noreferrer">following this example</a>)</p>
  
  <p>The source command is not recognized by Windows. Are the additional steps to the virtualenv command required for Windows, or is there an alternative usage of the source command?</p>
  
  <p>Note that the subsequent pip install commands worked (pip, tensorflow_gpu), but when I attempt to train using train.py  I get the following error:</p>
  
  <pre><code> File "train.py", line 27, in &lt;module&gt;
      from tensorflow.contrib.tfprof import model_analyzer
  ImportError: cannot import name 'model_analyzer'
