OS X not using most recent NumPY version
The new NumPY version would install (via pip) into the System path, where it wasn't being recognized by Python. To solve this I ran pip install --user numpy==1.7.1 to specify I want NumPY version 1.7.1 on my Python (user) path.
:)
Trying to update NumPY by running pip install -U numpy, which yields "Requirement already up-to-date: numpy in /Library/Python/2.7/site-packages". Then checking the version with import numpy and numpy.version.version yields '1.6.2' (old version). Python is importing numpy via the path '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy'. Please help me out here.
