title: how to pip install 64 bit packages while having both 64 bit and 32 bit versions?
body: <p>I have decided to learn generic algorithms recently and I needed to install Tensorflow package. Tensorflow run on python 64 bit only, so i install python 3.5.0 64 bit without uninstalling python 32 bit. because i was afraid to lose my packages on python 32 bit by uninstalling it. The problem is how can i force <strong>pip install</strong> to install a package on my python 64 bit version instead of 32 bit version.</p>
