title: Tensorflow AttributeError: 'NoneType' object has no attribute 'TF_DeleteStatus'
body: <p>Tensorflow is giving me this unresolved error:</p>
  
  <pre><code>Exception ignored in: &lt;bound method BaseSession.__del__ of &lt;tensorflow.python.client.session.Session object at 0x7f68d14b6668&gt;&gt;
  Traceback (most recent call last):
    File "/opt/anaconda3/lib/python3.5/site-packages/tensorflow/python/client/session.py", line 532, in __del__
  AttributeError: 'NoneType' object has no attribute 'TF_DeleteStatus'
  </code></pre>
  
  <p>The error has been discussed <a href="https://github.com/tensorflow/tensorflow/issues/3388">here</a>. The problem is it is not showing up consistently. However, it is showing up in my terminal frequently. Has anybody managed to get around it.Thanks.</p>
