Good news, in PyPy 1.7 they have fixed the namespace clash.
In PyPy 1.6, "import numpy as np" would give you "fake" numpy,
the micronumpy written by the PyPy team - which was a frustratingly
limited subset of the full NumPy API.
As of PyPy 1.7, you must explicitly use "import numpypy as np" to
get their micronumpy. This makes life simpler for 3rd party libraries
since "import numpy" will just fail, and they can use and test for
the PyPy mini-numpy explicitly if they want to.
