Numarray for Python 2.3

Does numarray-0.5.win32-py2.2.exe work with Python 2.3? If not, is
there a version that will?

No, not the last time I tried. It seems that Python 2.3 looks for a
different .dll structure than python 2.2.

Below is an extract from a recent posting by Perry Greefield to the
PySci list which sets out current development intentions for

I have copied your question, with this response, to Perry Greenfield.

Numarray will be the successor to Numeric. I talked with Perry
Greenfield from STSci at OSCON last week. STSci is developing

He said that pretty much the only things left before numarray is a
"feature complete" replacement for Numeric are PyObject array support
and Paul Dubois Masked Array (MA) classes. He wants a full
replacement before releasing 1.0.

I'll let him pronounce the official release dates, but it is
not so far off.

No dates fixed in stone, but here is the basic plan

0.6 to be released this week, this reorganizes numarray as a package

0.7 (few weeks?) Will include PyObject support

0.8 (2 months?) Will include MA support. At this point we hope to
replicate all Numeric functionality (other than the planned changes).

v1.0 will come out when 0.8 has been tested by users for a little while
(with perhaps a 0.9 if many changes and fixes are needed)

[Eric Jones] Numarray and Numeric will co-exist for a long while. Numarray is new
and therefore less well tested. It also has slower performance for
small arrays by about a factor of 3, but is faster for large arrays.
There are also many packages that rely on Numeric out in the wild,
>> and the transition will be slow.

There may be some rough corners where performance of numarray needs
optimization that haven't yet been handled (e.g. printing? slicing?)

Thanks. I don't need it just at the moment, but I was planning to
learn it during quiet moments. I can wait.
