title: How to install NumPy for Python 3.6
body: <p>I am using Python 3.6b3 for a long running project, developing on Windows.
  For this project I also need NumPy.
  I've tried Python36 -m pip install numpy, but it seems that pip is not yet in the beta.
  What's the best way to install NumPy for Python 3.6b3?</p>
  
  <p>[EDIT: Added installation log, after using ensurepip]</p>
  
  <pre><code>D:\aaa\numpy-1.12.0b1&gt;call C:\Python36\python.exe -m pip install numpy 
  Collecting numpy
    Using cached numpy-1.11.2.tar.gz

      Note: if you need reliable uninstall behavior, then install
      with pip instead of using `setup.py install`:
  
        - `pip install .`       (from a git repo or downloaded source
                                 release)
        - `pip install numpy`   (last Numpy release on PyPi)
