title: Tensorflow Compilation Speeding up CPU
body: <p>As I use the following command after importing tensorflow in python 2.7:
  <code>sess = tf.Session()</code></p>
  
  <p><strong>Warnings/errors:</strong></p>
  
  <blockquote>
    <p>tensorflow/core/platform/cpu_feature_guard.cc:45] The TensorFlow
    library wasn't compiled to use SSE4.2 instructions, but these are
    available on your machine and could speed up CPU computations.</p>

  <p>Please help me fix this so I may use my machine at its optimal power.</p>
