There was a problem hiding this comment.
I suspect this can be done more efficiently with 3 lines in place of the function:
pl = np.zeros(slc.shape[0], dtype=float)
dx = np.diff(slc, axis=0)
pl[1:] = np.cumsum(np.hypot(dx[:, 0], dx[:, 1]))

Would it be simpler to bump the numpy version to 1.8.0? Relevant ubuntu versions right now are at https://www.ubuntu.com/info/release-end-of-life: Plus this way we get np.full :-) |

I'm going to move everything over to #9151 for simplicity (sorry if people are getting lots of notifications...) |
