Hi, There seems to be a lone instance of "aghitza" that's orphaned. The corresponding trac username is "AlexGhitza", and the github username is "aghitza". Best, Alex On Thursday, January 19, 2023 at 1:14:16 PM UTC+11 Kwankyu Lee wrote: > Dear readers

[sage-devel] manual memory management for GAP?

2022-06-20 Thread AlexGhitza
Hi, I'm trying to help out a friend who is computing automorphism groups of lattices in Sage (using GAP under the hood). The computation is fairly long and memory-intensive and eventually results in sage.libs.gap.util.GAPError: Error, reached the pre-set memory limit (change it with the

[sage-devel] bug in matrix solve over inexact coefficients?

2020-05-21 Thread AlexGhitza
Hi, I'm observing the following with version 9.1 (but not with 9.0 where the behavior is correct): sage: m = matrix(SR, [0]) sage: b = vector([1]) sage: m.solve_right(b) (0) This should of course raise ValueError: matrix equation has no solutions It seems to be specific to inexact

Hi, I tried logging into trac today after a long time away, and failed. Thinking that I had just forgotten my password, I asked for a password reset, and then retried with the automatically generated password that trac emailed me. Still getting an authentication failure. Thoughts? Best,

Hello sage-devel, (I sent this from my email a couple of hours ago but it hasn't appeared on the list yet. I am trying again from within Google Groups. Apologies if it ends up being a duplicate post.) Schemes and their points are not yet properly embedded in the category framework. One of

John, I just ran into this problem and, while searching for a solution, found this post. I don't know if you eventually got it to work, but it turns out that the solution (under Ubuntu) is to install the package texlive-lang-cyrillic (probably because of Sha). Not quite Klingon, but almost :)
