Hi all,
This says that planning for migration to python 3 has begun.
http://blog.jarrodmillman.com/2009/11/numpy-14-coming-soon.html
It has been a month since 1.4 was released. Is there a status page
somewhere where one can checkup on progress for the same? Is Python
3.x support planned for 1.5?
Given all the discussions that have happened. I want to be clear
about my proposal. It is:
* 1.4.1 is an ABI break including datetime, hasobject, and a few place-
holders in the structures
* no future ABI breakages until after the Py3K transition (at least 18
months away) -- I don't foresee

I'm working in IDLE in Win7. It seems to me MPL gets stuck in
site-packages under C:\Python25. Maybe this is as simple as deleting the
entry?
Well, yes there's a MPL folder under site-packages and an info MPL file
of 540 bytes. There are also pylab.py, pyc,and py0 files under site.

This is not true. Consensus has not been reached.
I think 1.3.9 should be released and 1.4.1 should be ABI incompatible.

This isn't the question at hand anymore. The only question at hand
is what to label the no ABI breaking release.

This problem keeps bothering me for days.
If you need more sample to test it, I got one more. I tested it this
morning. And the "segmentation fault" happened at a specific place.
I guess, finally, I have to refer to the original eigenvalue algorithm or
Matlab.
Thanks.

Hi folks,
It sounds like a consensus has been reached to put out a 1.4.1 that is
ABI compatible with 1.3.*
If that's the case, and particularly if it's going to be a while before
1.4.1 is ready, I suggest that the 1.4.0 release be pulled from "current
release" status on the download sites.

Try:

standard caveats about float comparisons apply; perhaps
any(numpy.allclose(u, l) for l in array_list)

hi,
pyaudio is pretty good for recording audio. It is based on portaudio and
has binaries available for win/mac - and is included in many linux distros
too (so is pygame).
You can load, and play audio with pygame. You can use the pygame.sndarray
module for converting the pygame.Sound objects i

I assumed that we would simply give up the Numeric compatibility - does
