[SciPy-user] fft crashes python

[Alpha]

Hello,

I recently had similar problems. I could resolve them by uninstalling
the precompiled fftw libraries and replacing them by a freshly
downloaded and self-compiled version. Afterwards I deleted scipy from
the  /usr/lib/python2.3/site-packages/ directory and compiled and
installed it again.

Everything works fine now. I guess it might suffice to install the
self-compiled fftw library.

Contact me, if you need help with that.

Cheers,

Alpha
