Thanks Travis and Robert for the clarification; it is much more clear
what is going on now.
As the demo code shows, also a.flags['OWNDATA'] is different on its
way out of the pickle; which also makes sense now. So using that flag
instead of checking a.base for None is equivalent, at least in this

This is the expected behavior. It is not a bug.
NumPy arrays after pickling are views into the String that is created by the
pickling machinery. Thus, the base is set. This was done to avoid an
additional memcpy.
This avoids a copy, but yes, it does mean that you can't resize the array u
Hmmm, I wouldn't think that it is correct behavior; I would think that

None. If not, then who is really the one that owns the data?
It was my understanding that .base should hold a reference to another
ndarray that the data

Indeed they are, but it still needs active "pulling" on behalf of

I am having trouble pickling (and then unpickling) an ndarray. Upon
unpickling, the "base" attribute of the ndarray is set to some very strange

None).
I have tried on various platforms and versions of numpy, with inconclusiv

Hi all,
on behalf of the IPython development team, and just in time for the
imminent Debian freeze and SciPy 2012, I'm thrilled to announce, after
an intense 6 months of work, the official release of IPython 0.13.
This version contains several major new features, as well as a large
amount of bug

For it to work, one would need to actively push users towards it though...so it
would require a very clear pronouncement.
Matthew: I'm happy with the split we did with Cython. It leaves me free to
mostly ignore cython-users, and it saves users from thos 100+ post
As I mentioned before, numpy-related questions would be welcome on scicomp,
and this would have the advantage of bringing in scientists and
mathematicians from related fields who might be able to answer numerical
questions that sit between mathematics, programming, and science that you
