Hi,
I have a tricky problem with Numeric. Some time ago, I have generated
a huge and complex data structure, and stored it using the cPickle
module. Now I want to evaluate it quickly again on a workstation
cluster with 64-Bit Opteron CPUs - I have no more than three days to
do this. Compiling Python and running Numeric has been no problem at
all. However, I get an error message when accessing the data pickled
before. (I can load it...

Does anyone have a code snippet to compare those values so I can sort
the array of alpha-numeric values that include both characters and
integers in it?
I.e., if we have values like 4236 and 123234, I want 4236 to be second
because 4 is bigger than 1 rather than using the numeric comparison.
The strings can include character values and strings. Basically, I have
the bubble sort function, the question is how to compare those types of...

I have a function that uses the Numeric module. When I launch the
function csrss.exe consumes 60 / 70 % cpu power rather than having
python / Numeric run at full speed. Has anyone encountered this problem
before? It seriously messes up my Numeric performance.
I'm running 2.4.2 on xp.
Cheers, Jelle

Hello,
I suspect that there is a quite straight forward answer to this, but I can't
find it... I want to import an image and extract a matrix (or array) from it
with elements showing the RGB value of each pixel. But I want to be able to do
this with all types of image formats. It was suggested that a function such as
'B = numeric.from_image(A)' was used but I can't find it in any of the
libraries. I was hoping you could help me on this....

Hi,
I have the following loop that I think can be written to run faster in
Numeric. I am currently using Numeric.
range_va =
main.xsize= 600
main.ysize= 600
#msgva is an (600x600) Numeric array with mutiple occurrences of the
values in range_va
#sat_id is an (600x600) Numeric array with values ranging from -2 to 2

Hi,
I am posting here to seek for help on type conversion between Python (Numeric Python) and C.
Attachment A is a math function written in C, which is called by a Python program. I had studied SWIG and Python/C API a bit. I was able to pass numeric array (Numeric Python) into the C function and access/change these arrays.
Problem I am having is that I couldn't quite get the array converted back to some PyObject or something that...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
