 Hi,
 I'm trying to build numpy from svn on ubuntu edgy with atlas provided by 
 ubuntu
 package atlas3-sse2-dev which contains:

 /usr/lib/sse2/liblapack_atlas.so
 /usr/lib/atlas/sse2/libblas.so
 /usr/lib/atlas/sse2/liblapack.so

 I tried both with and without a site.cfg:


 [DEFAULT]
 library_dirs = /usr/lib/sse2
 include_dirs = /usr/include

 [blas_opt]
 libraries = f77blas, cblas, atlas

 [lapack_opt]
 libraries = lapack, f77blas, cblas, atlas
 
 Confusingly lapack_atlas resides in /usr/lib but even though setup.py looks 
 for
 it in that place it reports 'not found'.

 What should I try next?
 
 Change this:
 
 [lapack_opt]
 libraries = lapack, f77blas, cblas, atlas
 
 to this:
 
 [lapack_opt]
 libraries = lapack_atlas, f77blas, cblas, atlas
 

Thanks, but that didn't help:

[Numpy-discussion] pickable ndarray subclass

2007-04-14 Thread Christian K 
Hi,

could someone please provide example code for how to make a subclassed ndarray
pickable? I don't quite understand the docs of ndarray.__reduce__.
My subclassed ndarray has just one additional attribute.

Thanks, Christian
