No! The python 2.6 package is perfectly fine. Try to remove that, and
you are likely to hose your whole system. It sounds like your only
problem was that you had the numpy package installed, and it was being
found instead of the one installed from source.
Eric
I don't understand what you mean when you say "...you had the numpy package
installed,.." Are you saying a version of numpy came along with scipy, and
that was the one "being found"? Also, to run programs which need scipy.stats
I'll have to again install scipy. When I did that using Synaptic it broke my
system. In summary, I don't understand what caused the problem. Shall I install
scipy from source?
The version of numpy I installed last month from source is 1.61. I've just
found a couple files:
/usr/bin/numpy-1.6.1/doc/release/1.3.0-notes.rst
/usr/lib/python2.6/dist-packages/numpy-1.3.0.egg-info.
I'll assume those numbers 1.3.0 are not an issue.
