I grabbed scipy from CVS and built it last night, and I get an error when I try to use it: ImportError: No module named fastumath Some details on my system: OS: Linux, Mandrake 8.1 Python: python-2.1 Numerical: latest from CVS as of last night, 22.0a fypy2e: latest from CVS as of last night, 2.1.13.175.1250 ATLAS: 3.3.14 LAPACK: 3.0 When I look in /usr/lib/python2.1/site-packages/scipy_base, there is a file fastumath.so, so I am puzzled as to why the statement 'import scipy_base.fastumath' fails in scipy_base/__init__.py.

Can you import fastumath directly? E.g. cd /usr/lib/python2.1/site-packages/scipy_base python
import fastumath
Can you import scipy_base directly? E.g. cd - python
import scipy_base
Can you import scipy_base.fastumath directly? E.g. cd - python
import scipy_base.fastumath

I've seen this occassionally (during "cvs update -Pd ; python ./setup build ; python ./setup install cycles). The solution was to go into the right place and manually run setup_scipy_base.py (or the similar equivalent when it was somewhere else). But it seems like years since I did any scipy evaluation... best, -tony

I get this error when I try and run python from the main scipy build directory. If you checkout scipy and are in the scipy directory when you run python, Python tries to load modules and packages from the current directory, (and naturally does not find the compiled modules which are in the build/ subtree. Try going to your home directory before you run python. -Travis
I've just run up against the "no module fastumath" problem. Moving the working directory back to my home directory didn't fix this, because I had checked out the scipy module from CVS into my home directory, which creates a "scipy" subdirectory automatically. Thus python was searching my CVS-tree from the modules. Trivial solution: move the scipy CVS directory out of my home/working directory. Ideally the CVS module name would be different from the python module name. Can you change CVS module names without messing things up (to Scipy instead of scipy, for example)?

Why don't you rename it yourself? After cvs -d ... checkout scipy do mv scipy scipy_cvs and the problem is solved (you can then do 'cvs update' inside scipy_cvs, for instance). It would be much more difficult to change the name in the CVS server and, personally, I don't see any point in that. Btw, I keep all CVS versions of various software in one directory named as `cvs'. I never use python in that directory which avoids messing things up. Regards, Pearu
