I only use "sage -python" or "sage -ipython" with PyCUDA stuff, so that
part's probably right. I'm running 64-bit Fedora and 64-bit CUDA (straight
from NVIDIA, I had to fight a fair bit with this to work with Fedora 11's
4.4 gcc), and PyCUDA's tests work fine with Sage's Python. I would try to

I actually got to the point where it would install using a similar
approach. I've been using the special shell environment for sage that
forces the correct python paths and so forth. Unfortunately my install
segfaults when I try to run the tests. My systems python will run the
pycuda tests

I'm guessing that GG doesn't mean anything special, but is just a name
similar to G, and gap(G) is transforming G into a gap object. I'm not
exactly clear when this sort of thing needs to be done, but I guess
I'll learn over time.

Hello,
How to properly remove a package ?
In documentation there is no mention on how to do that.
Particularly, I'd like to remove sagenb-0.7.5.1 from my Sage installation.
Should I just remove the directory sagenb in
sage-4.3.3/local/lib/python2.6/site-packages/sagenb-0.7.5.1-py2.6.egg ?

Hi,
I'm having trouble constructing p-adic cyclotomic fields in Sage (v
4.3.3). For instance, if I try to make Q_p(zeta_p) (for, say p = 3),
by entering
sage: S. = Qp(3)[]
sage: K. = Qp(3).extension(x^2 + x + 1)
I get the error:
NameError: global name 'split' is not defined

I just got the sagetex package to work with my Tex distribution.
The question I have is, how do I get SAGE to work out the resulting

in the sagetex package and also in the SAGE manual, but it only tells
me that I have to ru

I suppose it is, although I'm not really sure what it actually does.

oooh wait wait wait. I've said something totally confusing.
My previous two posts apply to rational fractions... for which indeed,
the numerator method gives the 'correct' answer ! The issue I raised
in my original post is the 'funny' behaviour when you ask for the
numerator of something in QQ[x]
One further example perhaps, to be more convincing :
sage: N= (2*x).numerator()
sage: N.prime_divisors()
[2, x]
sage: [valuation(N, p) for p in prime_divisors(N)] # innocent-
looking piece of code
...
ArithmeticError: The polynomial, p, must have positive degree.
I do think the innocent piec
hmm it's not mathematical, it's just that IMHO n should belong to
QQ[x], not ZZ[x]. I do see your point though, in that the coefficients
should be mathematical integers (or "may as well be"). And I do see
now that it is intentional.
Think about it : if i wanted to use your metaphor, over QQ the

sage: var('x,y,z')
(x, y, z)
sage: solve([sqrt(x)-2,y-2*x,x-z**2],[x,y,z])
[[x == 4, y == 8, z == -2], [x == 4, y == 8, z == 2]]
