Hello,
I use the Python Numeric package extensively, and had been an
avid user of the "old" scipy. In my view, both pieces of software
are truly first rate, and have greatly improved my productivity in
the area of scientific analysis. Thus, I was excited to make the
transition to the new scipy core (numpy).
Unfortunately, I am experiencing a problem that I cannot sort
out. I am running Python 2.4.2 on a Debian box (V3.1), using
gcc version 3.3.5, and ATLAS, BLAS, and LAPACK libraries
built from scratch. When building numpy everything seems to
go AOK. But trouble soon follows.
As a sanity check, I run the diagnostic tests that come as
part of the numpy package:
from numpy import *
from scipy import *
test(level=N) # N can vary from 1 to 10. :
No matter which test I run, Python crashes hard with only
the following output: "Floating exception".
This could be related to the Debian glibc bug that has been discussed before. Aparently the Debian version of glibc had some issues with SSE. This is the same behavior experienced by others on the Debian platform. There is a patch, but I'm not sure what it is.
See, for example:
