Hi, this is a follow-up to my original posting.
It turns out that the problem with TkAgg in 'matplotlib' isn't really
a sage-specific issue. It is more a problem with the 'matplotlib'
installation scripts.
I tried a clean install of 'matplotlib' within a clean, stand-alone

What kind of cluster are you using?

Also, you can use mpi4py to parallelize your own work building on top

Will this work on a cluster or just a multicore pc or both?

Hello,
When I try:
var('t')
r=vector((t^2,5*t,t^2-16))
v=derivative(r(t),t)
norm_v=v.norm()
print r
print v
pos=r(0)
print pos
vel=v(0)
i receive an error for the last command vel(0)...i suppose i'm doing
something wrong
see error below
Thank you for help...

Just to confirm, I was doing some other random plotting of points (not
lines, just scatter points) today with axes=False, and once again this
cropped up - off by one pixel with the line x=0 and some points which
were definitely on that line, yet they weren't on it. This was with

From Lisandro (author of mpi4py). Sounds like at the very least we
should be shipping a newer mpi4py.

I don't think that functionality is in sage right now. We have cddlib
and PALP as standard components, and lrs and 4ti2 as optional and
experimental packages. It looks like LattE macchiato requires 4ti2,
ntl (standard in sage), and gmp (equivalent to mpir in sage). So it
shouldn't be very hard t
Ah, I got it figured out. In previous attempts, the host OS was
Windows 7. I tried it on XP and it works fine. Might just be a
firewall issue with Windows 7.
Thanks for your support though.

Hello!
Is there an (efficient) way to compute the Ehrhart polynomial of a
lattice polytope in Sage? Is there an implementation of Barvinok's
algorithm contained in some Sage package?
All I found on the topic was a message on this list, discussing the
packaging of the barvinok library for Sage. Ho

Do not know how to configure virtualbox, but you should
1. either use IP address of the virtual machine
2. forward packets from port 8001 to the virtual machine, for example
something like this (part of my apache2.conf)

Hi all,
For the last several days, I've been trying to properly configure port
forwarding in VirtualBox so that I can have the VM accessible to other
machines on the network. After doing research, I came across these
sets of commands:
VBoxManage.exe setextradata "Sage 4.2.1" "VBoxInternal/Device
