title: Upgrade pip to ver18 on anaconda
body: <p>I am using anaconda 64-bit for python v3.6 on Windows 10.</p>
  
  <p>Whenever I use pip on anaconda, I get the following message;</p>
  
  <pre><code>You are using pip version 10.0.1, however version 18.0 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.
  </code></pre>
  
  <p>I read that the safe way to upgrade pip on anaconda is to use conda;</p>
  
  <pre><code>conda update pip
  </code></pre>
  
  <p>However, using the conda command does not upgrade to ver18. Is it safe to use <code>python -m pip install --upgrade pip</code> to force pip to be upgraded to ver18? Any risk of breaking anaconda? Anyone tried? </p>
