Stop pip installs dependencies already installed with apt-get

How can I make sure that packages installed with help pipdo not install dependencies already installed with help apt-get?

For example, on Ubuntu you can install the Numpy package with apt-get install python-numpy. Which is installed on:

usr/local/lib/python2.7/dist-packages

I noticed that when I install a package that requires numpy using pip, for example, pip install scipyinstead of skipping the numpy dependency, it installs again in another place.

/usr/lib/python2.7/dist-packages

What needs to be done is to skip any python packages installed globally, right?
