title: Windows: Using Tensorflow with Python 3 instead of Python 2 (Docker)
body: <p>My problem is very similar to the one stated here:
  <a href="https://stackoverflow.com/questions/35771285/using-tensorflow-through-jupyter-python-3">Using TensorFlow through Jupyter (Python 3)</a></p>
  
  <p>So, I have both installed Python 2 and Python 3 (3.4.3). Currently Tensorflow runs only with Python 2 but I would prefer using a Python 3 kernel.
  The difference to the thread: I have a Windows System and use Docker to get TensorFlow running.</p>
  
  <p>If I open regular Jupyter Notebooks (not using TF) I use Python 3 by default. I also may change the kernels (and their names) by the way described in the abovementioned thread, however this does not affect the Python-2-Kernel for TF, since it seemed to be stored in another directory. In the TF-environment the only kernel I can access is this Python 2 kernel. 
  Unfortunately, I cannot even find out that directory and even not where my Notebooks created with TF are stored; it all seems to be hidden by Docker.</p>
  
  <p>Thanks a lot for your help!</p>
