Thanks for the effort of bringing pynifti (and pymvpa) avaliable. For me (on Ubuntu 9,04, or Mac Leopard) $ sage -i pynifti-p0 unfortunately did not work directly. However, downloading the sources 'pynifti_0.20090303.1.tar.gz' and 'pymvpa_0.4.2.tar.gz', then $ sage -shand $ make all an

What I said about inserting loads(dumps(self)) holds on openSUSE 11.0 Intel Core Duo, but I am afraid it doesn't on sage.math. Anyway. I think sage -gdb should allow me to see what exactly went wrong (freeing non-allocated memory? double free? whatever?), and also show me, in what line the memory

[sage-support] readline? problem

I have a problem with Sage and maybe readline on an ubuntu box. If I type sage: squ then it partially completes to sage: squarefree_ Then it lists the options ("squarefree_divisors squarefree_part") and puts the cursor in the wrong place: the cursor ends up on the "s" in "squarefree_".

[sage-support] Re: Division by zero in calculation of Weil Pairing

Hmm, In looking at ell_point.py at line 1181 it looks like it does the right thing. Somehow the pari error of division by 0 (perhaps in non- prime finite fields?) doesn't get raised as a ZeroDivisionError. This is a problem with the interface with pari: p = 100019 K. = GF(p) L. = GF(p^2) K(1)/K

[sage-support] Re: Division by zero in calculation of Weil Pairing

Slight change. The code I gave works, but the following fails. I really don't know what there is about a non-prime finite field that causes this. Victor p=100019 E = EllipticCurve(j=GF(p^2,'r')(1728)) M = (p+1)//3 # find an element of order 3 while True: P = M*E.random_element() if P != 0:

[sage-support] Division by zero in calculation of Weil Pairing

In calculating the Weil Pairing of two points I get a pari division by zero error. Needless to say this shouldn't happen. I think that the solution is that if either of the miller_functions that are calculated yield a 0 then the value of the Weil Pairing must be 1. Here's some code that provoke
