Hello,
There has been some interesting discussion regarding cKDTree recently on
the scipy-dev list (see thread starting at
http://mail.scipy.org/pipermail/scipy-dev/2012-July/017737.html) and
I've been reading it with a lot of interest. Based on what Sturla is
saying within these messages, the cython/numpy interface used in the
Ball Tree (and several other scikit-learn cython scripts) is no longer
the preferred way to access numpy data buffers from cython.
memoryviews in cython are rather new (I believe they require cython
version 0.16+), but I think using them would make our ball tree code
both more readable and less likely to face deprecation in the future.
How do folks feel about using this sort of bleeding-edge cython syntax
in scikit-learn?
Jake
