Hi List,
I am trying to install numpy 1.0.1 on Linux. (Numeric and numarray have been
fine)
System info: Redhat Linux kernel 2.4 with gcc 3.2.3 but no separate FORTRAN
compiler.
It has a Fortran 77 compiler (the one which comes as part of gcc)
My questions:
1) install can't find ATLAS (*.a)
Sorry Robert,
My email sent to mail-list bounced back 5 times.

I assume that this means numpy was not installed successfully.
No, it means that you are running
Thank you David M. Cooke and Robert.
Now I changed directory and ran python,

Hi Robert
The override does the trick.
It worked. Thanks and have a nice weekend.

Okay, here is the full scoop:
* The multi-threaded ATLAS is always tried first. This doesn't work for
you
since you compiled your Python without pthreads.
* The standard library directories (/usr/lib,
Hi list,
When I do large array manipulations, I get out-of-memory errors.
If the array size is 5000 by 6000, the following codes use nearly 1G.
Then my PC displays a Python error box. The try/except won't catch it
if the memory error happens in astype instead of array1* array2

hi list,
I am trying to find 1-D cubic spline function. Google search yields
that there is a function called spline_filter1d in numarray. But I am
not able to call it.
Would someone point me to 1-D cubic spline function either in numarray
or numpy?
I can find source codes and enter in Python.
. You want to
look at scipy, a set of packages built on numpy that provide more
sophisticated domain-specific functionality. Specifically, ndimage is
part of *scipy*, not numpy.

hi list,
The following array manipulation takes long time because I can't find
ways to do in row/column, and have to do cell by cell. Would you check
to see if there is a nicer/faster way for this non-linear operation?
for i in range(rows):
for j in range(columns):
a[i][j] =
(maximum(0, a**2-repeat(b*c, columns).reshape(rows, columns)))

I tried to build numpy 1.2.1 on Solaris 9 with gcc 3.4.6

Hi,
Does:
import md5
work? If it doesn't, it's a packaging problem. md5 must be available.
