Where did you install atlas ? What does ldd says about lapack_lite.so module ?
More likely, your problem is that you install atlas into
My understanding of the root of the problem is that you end up with
doing many evaluations of sinc. If this is so, one suggestion is to go
with pre-computed filters. For example, if you are resampling from 9
points to 10, essentially you're trying to go from a function that is
defined on points 0,
Hi Everyone,
I am trying to give an update here so that maybe it will be easier for
someone to help me out now.
I have gone through the lapack installation and the atlas installation and
everything seems to have worked fine. Everything was compiled using the
'fPIC' option and I figured out how t
I resolved the issue after having another look at the build scripts. Thanks
everyone for your help!
For reference, the problem arose from a bad site.cfg file. In the past this
file was necessary on ArchLinux to make numpy find the atlas libs. I tried
removing it and now numpy to compiles correc

That's the documentation of the old Numeric package, though the name of
the URL is severly misleading.

Any suggestion? Thanks at first.

Hi,
I'm trying to make a weave python extension to use in my program. I already
did it in inline, but that doesn't work with py2exe (needs compiler), so I'm
creating extensions instead using ext_tools.
Is there a way I can use blitz with ext_tools? so that I can refer to numpy
arrays like a(x,y)

Hi,
I was wondering whether it was really worth having a lot of magic
going on in fcompilers for flags like -msse2 and co (everything done in
get_flags_arch, for example). It is quite fragile (we had several
problems wrt buggy compilers, buggy CPU detection), and I am not sure it
buys us much

No, it won't, and no, don't force it. I doubt dpkg would allow
Hi,
I was wondering about the following behavior:
a = np.random.randn(10)
b = a[:. np.newaxis]
print b.flags # F_CONTIGUOUS and C_CONTIGUOUS are both false
Is it for simplicity purpose, or is there a more fundamental reason why
a rank 2, 'column' vector can't be F_CONTIGUOUS in this case ? D
