ImportError:
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.
Original error was: cannot import name multiarray

Seeing this in 2.7 now too... not sure why I was only seeing it in 3.x before.
