warning: Numeric and amd64

Community matplotlib-users

On my AMD64 (using pre-compiled version as packaged by enthought) I get the expected results from RandomArray under Numeric ie:
>>> from RandomArray import *
>>> normal(2,2,10)
array([-0.43560529, 2.67296922, 0.84804749, 4.26332831, 0.64425385, 3.43939352,
             4.07021809, 3.6235764 , 2.93580639, 1.81101392])

Hi,

look at this:

from RandomArray import *
       
normal(2,2,10)
       

array([ 2., 2., 2., 2., 2., 2., 2., 2., 2., 2.])

This is Numeric 23.1 compiled on my AMD64!!! I ran the same tests on a 32bit P4 and it ran fine.
Has anyone else seen this before?

For those that didn't understand, the normal function as called above, is supposed to give me ten samples form a normal distribution with mean = 2 and standard deviation = 2

luckily:

from numarray.random_array import *
       
normal(2,2,10)
       

array([-0.04525638, 4.31467819, -0.17468357, 5.29377031, 0.84202135,
       5.29593539, 4.69651532, 1.61354655, 1.10839236, 1.7743317 ])

If anybody still needed a reason for switching to numarray, there you go!

I anybody here subscribes the numeric or numarray mailing lists (i.e. if they even exist) could you please forward this message to them?

Jon,

was you pre compiled Numeric compile for amd64 or for x86?

I think this is a result of the compilation .

Jon,

I think this is a result of the compilation .

Pearu Peterson, the guy who does f2py for SciPy, also commented
recently on numpy-discussion@...258... that he had found and fixed
this problem in Numeric for SciPy. He posted a patch which I also
applied to Numeric on Source Forge; that is still unreleased. The
contents of the patch were already in numarray.random_array.
