  <p>So as I understand it needs some other python version? my python version is 
  <code>python --version</code> Python 2.7.6</p>
  
  <p>Also I tried (and it works):</p>
  
  <p><code>export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.12.1-cp27-none-linux_x86_64.whl
  </code></p>
  
  <p><code>sudo pip install --upgrade $TF_BINARY_URL</code></p>
  
  <p>But I wonder why installation via <code>sudo pip install tensorflow</code> not working?</p>
