title: Installed Anaconda 4.3.1 (64-bit) which contains Python 3.6 but pip3 missing, cannot install tensorflow
body: <p>I downloaded the latest stable Anaconda install off the Continuum website which turned out to be Anaconda 4.3.1 (64-bit) and comes with Python 3.6.0. I am in a Windows 10 environment.</p>
  
  <p>However pip3 is missing and I cannot install any Python 3.x packages via pip3. </p>
  
  <p>What am I doing wrong? </p>
