This error usually means that NumPy was built and linked against a
Python build where unicode strings were 2-bytes per character but you
are trying to import it on a Python build where unicode strings are
4-bytes per character. Perhaps you have changed your build of Python
and did not remove the build directory of NumPy.
Try
rm -fr build
in the numpy directory (where you run setup.py) and build again.
You can tell how many bytes-per-unicode character your system is built
with by looking at the output of sys.maxunicode
