hi together,
how can I install pytables into sage? I found it in some old
presentations as a planed feature, but apparently it was dropped?! Or
is there any other way to read hdf or netcdf files with sage?
Thanks

Hi all
I need to solve a LP so I have installed 'csc':
sage: p.solve(solver='cbc')
and then copy and paste the example in
http://www.sagemath.org/doc/reference/sage/numerical/mip.htm that is:
sage: p = MixedIntegerLinearProgram(maximization=True)
sage: x = p.new_variable()

I have set TkAgg as the matplotlib backend in my matplotlibrc resource
file. I continue to have errors when I try to 'import pylab'. To
make certain it was not a Tkinter issue, I tested Tkinter and re-
installed matplotlib via ./sage -f matplotlib-0.99.1.p2
I'm running SLED 10.2 and built sage
Hello !!!
Your problem comes from the fact that the CBC packages got updated
very recently, and is compatible with the brand-new implementation of
the MIP class in Sage... I guess you need to use the last Alpha
version of Sage, or to wait until the next stable version is released.
Sorry for the
A temporary solution is of course to use the FORMER version of the CBC
package.
To do so, please type :
sage -f http://www-sop.inria.fr/members/Nathann.Cohen/cbc-2.3.p0.spkg
But these early versions of MixedIntegerLinearProgram have been
updated much since, so the best way for you is still to
Dear all,
Suppose I have polynomials over rational(Q) field although coefficients are
integer.
I want to transform these polynomials over some finite field say GF(7). I
write the
following program which does not work.
R.x,y=QQ[]
f1=2*x-3*y-1
f2=x^2+y^2-5
R.x1,y1=ZZ[]
f3=f1(x1,y1)
f4=f2(x1,y1)

It calls off to PARI, so it probably works (or can trivially be made
to work) over any base that PARI supports. In case it isn't

I want to run Sage on our 8-CPU, 64-bit Scientific Linux 4.8 machine.
Yet there seems to be no 64-bit version of Sage specifically for
Scientific Linux.
What there is: Debian GNU, Ubuntu, openSUSE, Mandriva and three
versions of Fedora.
Not sure how to proceed.
Will any of these run OK on

Hello,
Could you please advice the way to plot three-dimensional array?
Something like plot3d or counter_plot, but in case the data are
already calculated in array and there is no way to call f(x,y).
Best regards,

Its easy enough to code this in sage. This seems to work over any
field:
def ps_inverse(f):
if f.prec() is infinity:
raise ValueError, series must have finite precision for
reversion
if f.valuation() != 1:
raise ValueError, series must have valuation one for
reversion

Thank you both! Your examples and suggestions are very useful and it

I think the point is that if an application has to store anything in a
user directory, a dot directory is a consistent one to create and use.
Most applications store data as actual files somewhere on the
filesystem, so the only stuff left to store is configuration data. The

Moving the default out of the .sage folder by default would probably
not get accepted, but that wouldn't really fix your issues anyways
(and you can store the files in whatever folder you want right now).
Well, there is a whole bunch of issues, and you picked the least

There is no right answer. Sometimes, I want uploads from different

have the same
They would (continue to) point at the already existing beezer.
Beezer's book wouldn't explicitly reference beezer, since all
references should be relative in that collection of worksheets.
Yes, but then you probably sooner or later need a tool for merging two
such collections of worksheets.
First, thank you for help. Secondly, I tried to set SAGE_PATH but it
didn't work.
The packages I typically need are installed in:
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-
packages
So, if I set SAGE_PATH to this directory, sage will display all sort

On the same track, if sage is built from source on Richard's eight-CPU
machine, will it be able to take advantage of the multiple processor
cores? If I remember correctly, in a previous thread here a few
months ago, the answer was negative. If so, why? Sage is based on
