Do you have lapack-3.0? Numeric-20.2.0 (better get 20.2.1) is interfaced to new faster lapack routines. You could check it by [packer@taco lib]$ strings liblapack.so.3 | grep dgesdd dgesdd_ [packer@taco lib]$ best regards -- Gerard On Wednesday 31 October 2001 16:50, Edward C. Jones wrote:
The following Python program:
import Numeric, LinearAlgebra
a = Numeric.identity(5) v, s, wt = LinearAlgebra.singular_value_decomposition(a)
gave the following error:
Traceback (most recent call last): File "./silly.py", line 3, in ? import Numeric, LinearAlgebra File "/usr/lib/python2.2/site-packages/Numeric/LinearAlgebra.py", line 8, in ? import lapack_lite ImportError: /usr/lib/python2.2/site-packages/Numeric/lapack_lite.so: undefined symbol: dgesdd_
When I installed Numeric-20.2.0, I changed Setup.py to:
# delete all but the first one in this list if using your own LAPACK/BLAS sourcelist = ['Src/lapack_litemodule.c',] # set these to use your own BLAS library_dirs_list = ['usr/lib'] libraries_list = ['/usr/lib/libblas.so', '/usr/lib/liblapack.so']
What is the problem?
Thanks, Ed Jones
