[yt-users] Changing na => np internally

[Matthew Turk]

Hi all,

There's been quite a bit of discussion on yt-dev about changing the
internal convention in yt of using "na" for numpy (which originally
stood for "numarray") to "np", which is the commonly used shorthand.
We'll keep around "na" in the yt.mods namespace, which means your
scripts should *not* need any adjustment.  But, if you have made a
number of substantial changes to the internals of yt in your version,
any updates after this change is made may pose problems and may need
to be hand-modified.

If you'd like to contribute to the discussion (we're waiting until
next week to make the switch) please do so on yt-dev or here.  This
change, which touches many many files, was not decided on lightly and
we're trying to ensure that the transition is smooth without any
external effects.  Here's the thread:

(Note that tomorrow starts a new archive month, so you might need to
switch the URL for any new messages after today.)

Again, this should not pose any issues for you unless you have
modified yt internals.  If you have done so and would like help
updating, please reply to this message or contact yt-dev.

Best,

Matt
