Maybe this is for the Scipy list but followed the instructions but the command:
$ sudo python setup.py install
to install Scipy failed because it couldn't find Lapack. However, the export
commands were set as:
$ export BLAS=/usr/local/lib/libopenblas.a
$ export

Many thanks Pat - the numpy discussion list is brill.
Go ahead and see if the CPython developers would be interested as it is a
problem that appears all the time on boards/lists.

I've used numpy with py2exe and py2app out of the box
I've been using Numpy/Scipy for 5 years so know a little on how to get around
them. Recently, I've needed to either freeze or create executables with tools
such as PyInstaller, Cython, Py2exe and others on both Windows (XP 32-bit, 7
64-bit) and Ubuntu (12.04) Linux (64-bit). The test program
with your freeze setup.
Most of these tools don't support locally imported extension modules.
Does this help you get oriented on your problem?

Could the following be written without the direct for-loop?
import numpy

r = numpy.ones(25, dtype='int')
# s is a list of values (of any data type), eg.
s = [47, 27, 67]

Sounds great. Would cross-post on the Scipy list as that is where the
scipy.sparse developers hang out.

A suggestion:
How about releasing Numpy for the AMD64 version first (without Scipy) and then
follow up with a later release with Scipy support? This would satisfy
Numpy-only users which can't be a bad thing rather than having a version that
is not usable (I believe) by either Numpy or Scipy
Okay. Maybe a bit harsh, but wouldn't it be better not to have the release as
available if it cannot be imported?

On Sat, Jun
The machine in question is factory installed with:
OS: Windows Vista 64-bit SP2
Processor: Intel Core2 Quad CPU, Q6600 @ 2.4Ghz @2.4GHz
Memory: 8Gb
Apart from Python 2.5.4 nothing has been installed on this machine as it is
being used only to run Python programs.
Python 2.6.1 was installed
Ticket# 1084
(http://projects.scipy.org/numpy/timeline?from=2009-06-09T03%3A01%3A59-0500precision=second)
says that the numpy import on Windows Vista x64 AMD systems works now. Is
this for Numpy 1.3 or 1.4 and if 1.3 has anyone tried it successfully? Thanks.

Hello! I'm reading a text file with two numbers in str format on each line.
The numbers are converted into integers. Each integer is then assigned to a

array assignments work ie. both ij[index, 0] = r and ij[index,
When you pickle a numpy/scipy matrix does it have to be initialized by another
program? For example:
Program One:
A = scipy.asmatrix(scipy.empty((i, i)), dtype=int)# initialize
matrix A
do something with A
pickle.dump(A)
Program Two:
pickle.load(A)
