title: upgrade python package from wheel file using pip
body: <p>I am trying to use a wheel file to upgrade some python packages through pip.
  I have installed pandas 19.2 for my python, and I also have <code>.whl</code> file for pandas 23.0. I would like to upgrade pandas from 19.2 to 23.0. I searched online. I could only see people using pip install with a wheel file.
  Is it possible to upgrade from the wheel file? Will <code>pip install mypandas.whl</code> create any problems? How about its dependencies? Will pip <code>install --upgrade</code> allow to take <code>*.whl</code> as its input?</p>
