title: TensorFlow library wasn't compiled to use SSE4.2, AVX, AVX2, FMA in pycharm
body: <p>I am using pycharm to code and I successfully download tensorflow. But it gives me the warnings as:</p>
  
  <pre><code>The TensorFlow library wasn't compiled to use SSE4.2 instructions, but 
  these are available on your machine and could speed up CPU 
  computations.
  The TensorFlow library wasn't compiled to use AVX instructions, but 
  these are available on your machine and could speed up CPU 
  computations.
  The TensorFlow library wasn't compiled to use AVX2 instructions, but 
  these are available on your machine and could speed up CPU 
  computations.
  The TensorFlow library wasn't compiled to use FMA instructions, but 
  these are available on your machine and could speed up CPU 
  computations.
  </code></pre>
  
  <p>I saw other links and it doesn't solve my question. I tried to install tensorflow again by Source. And I stuck with building the pip package:</p>
  
  <pre><code>$ bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package
  </code></pre>
  
  <p>And my computer gives me the error:</p>
  
  <pre><code>ISO C++11 does not allow conversion from string literal to 'char *' [-Wwritable-strings]
  </code></pre>
  
  <p>I use mac and I don't familiar with Cpp so don't understand what it means.
  Anybody can help me solve this question? </p>
