Just a quick heads up: on Python Anaconda 3.3.2 np.load leads to a segfault. I am not on a computer for a week, but I saw that just before leaving. If I remember right, it is a simple matter of doing:
a = np.zeros(10)
np.save('a.npy', a)
np.load('a.npy')
I haven't submitted a bug report, because I didn't have time to check things properly. I suspect that it might be a problem of the compilation, rather then numpy itself, so the Anaconda team might want to check.
Sorry for the incomplete report. I thought that it was better to submit an incomplete report now than wait a week.
