=> You were absolutely right:
I had another Numeric package install in my PYTHONPATH. It overwrode the
system package at:
/usr/lib/python2.5/site-packages/Numeric/Numeric.py
I just deleted
/home/timmie/development/python/modules/modules_library/Numeric and now
everything to goes nice. I can use my Ipython again with numerics ;-)
Well, I guess the problem arose from the a time when I didn't have
network access.
I just threw python modules from the net into my PYTHONPATH without
using the Synaptic package manager.
Nice that this is now solved. Thanks for your quick answer and help!
Kind regards,
Timmie
