I ran into a problem with my numpy version (numpy was already installed):
Found existing installation: numpy 1.8.0rc1
Cannot uninstall 'numpy'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I fixed it with:
sudo pip install -r requirements.txt --ignore-installed numpy
