[sage-support] Re: problem after moving sage folder
Thanks for your help! cp does not have the -a option on my mac and cp -pR leads to the following error message after startup: Warning: something went wrong updating the easy-install.pth file. However, this time no other problems occurred and I was able to run the notebook server from the new directory, so I proceeded with running ./sage -upgrade. Another warning message came up: WARNING: This is a source/based upgrade, which could take hours, fail and render your Sage install useless!! It's not a problem since I'm running it on the Sage copy now, but 'hours' is what a fresh compilation from source would take anyway, so would I possibly be better off installing the whole thing from source? I'll see how long it takes. If it works, I shall try Mike's tar approach to move the compiled version from one laptop to another.

My guess is that using cp -a (which is the same as cp -dpR) works. The -d preserves links. This is using gnu cp; I don't know about a mac, though I think the archive option -a is even better there. mabshoff: comments?

[sage-support] Re: Making pylab.plot() and pylab.show() in Sage
Hi Gus,
What's wrong with Mike Hansen's suggestion in this thread?
In order to get that to work in the notebook, you don't want to use
pylab.show(). Instead, you'll want to use pylab.savefig('fig.png')
which will save the plot to a png file.
fig.png should be a separate file in your notebook folder.

[sage-support] Re: Importing modules and packages from gobal python install
Flavio, I will defer to a more expert Sage user on importing global python libraries into Sage but I will offer my own experiences in installing libraries into Sage. Since Sage has a complete Python installation in it (accessible through sage -python), I have been able to install the few Python packages I needed directly into Sage (e.g., PyCUDA) by using sage -python instead of python in the installation instructions and explicitly giving the Sage root directory. If you give the names of the packages you're looking to use with Sage, I (or we) can try it on my machine.

This is not really a complete description of Matlab's behavior in this situation. If you simply define f(x) = 1/x and apply fzero, without requesting any additional information, you get: f = @(x) 1/x; fzero(f,-1,1) ans = -2.6773e-16 However, you can ask Matlab to provide more information via: [x,fval,exitflag,output] = fzero(f,-1,1); Now, fval is a huge number and output.message indicates that the function might be singular. Similarly, Mathematica yields a numerical zero but issues a warning. Now, you can find that Sage uses SciPy's implementation of Brent's algorithm when tackling this problem by typing find_root?? and SciPy provides similar functionality as Matlab, in this case. What I find particularly puzzling, though, is that scipy.opitimize.brentq, raises an error for this problem, at least when applied to the interval [-1.0, 1.0]. On the other hand, brentq runs without reporting a complaint when applied to the interval [1.0, pi]. See below.

[sage-support] Does sage -clone overwrite previous clones?
Dear Support,
Regarding the clone command:
Suppose I have cloned 'test1' at some point in the past. Suppose
further that I have upgraded my main branch several times. If I now
decide I still like the name 'test1' for a clone, can I just do
sage: hg_sage.clone('test1')
without further ado and assume it will destroy the previous branch, or
should I delete that branch first, or should I never ever use the same
branch name again until I build a completely new Sage? (Or none of the
above?)
Thanks!

Is there any way to do that (other than explicitly calling the timeit module for each one, which is totally not worth it for my purposes)? - kcrisman --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Re: Importing modules and packages from gobal python install
Thanks Ahmed, I wish Sage could integrate better into my system, since I develop mainly in Python and wanted to be able to run my code from within Sage, but without having to have duplicate installs of the packages I need to import. But for the time being, I think I'll do just that, but I would rather see a version of Sage that would take advantage of everything available on a standard Linux system instead of replicating it. thanks, Flávio On 16 mar, 11:38, Ahmed Fasih wuzzyv...@gmail.com wrote: Flavio, I will defer to a more expert Sage user on importing global python libraries into Sage but I will offer my own experiences in installing libraries into Sage.

On a mac, the ditto command is nice. Warning: something went wrong updating the easy-install.pth file. However, this time no other problems occurred and I was able to run the notebook server from the new directory, so I proceeded with running ./sage -upgrade. Another warning message came up: WARNING: This is a source/based upgrade, which could take hours, fail and render your Sage install useless!! It's not a problem since I'm running it on the Sage copy now, but 'hours' is what a fresh compilation from source would take anyway, so would I possibly be better off installing the whole thing from source? I'll see how long it takes. Well, IIRC, it won't have to compile spkgs that didn't change. However, for every spkg that has been updated, you will have to compile that spkg. Typically it's much faster than compiling fresh from source.

[sage-support] jsmath bitmap fonts in sage 3.4 and solve command
Hello, I installed today new sage with jsmath bitmap font. These fonts did not work, I had to put the bitmap fonts from old installation to / opt/sage-3.4-linux-Debian_GNU_Linux_5.0_lenny-i686-Linux/data/extcode/ javascript/jsmath manually. From this reason I report this problem (maybe a bug). R question: there are two directories with jsmath.js file: data/ extcode/javascript and local/notebook/javascript. Why? How to find out, which one is used in notebook. And another question: How to find out which solve command is used to solve equations? From reading the files calculus.py I found that solve command allows explicit_solutions option, but solve? and solve?? point to /opt/sage/local/lib/python2.5/site-packages/sage/calculus/ equations.py which do not contain anything about this option. However explicit_solutions works also in notebook.

TypeError: Gap produced error output
Error, the Small Groups library is required but not installed

I am running Sage under Fedora 10, 32bit. The command sage -i
seemed to install the two packages without complaint.
So is this still a known problem?
Thanks,
Dave

Does anyone have an idea what the problem could be?
I finally figured out that (a) I was in the wrong directory
and (b) spaces matter for shell scripts. It now works in Linux.
I'm going to test in on a mac OS 10.4 and then post a link to the trac ticket
if that works.

[sage-support] Re: jsmath bitmap fonts in sage 3.4 and solve command
ma...@mendelu.cz wrote: Hello, I installed today new sage with jsmath bitmap font. These fonts did not work, I had to put the bitmap fonts from old installation to / opt/sage-3.4-linux-Debian_GNU_Linux_5.0_lenny-i686-Linux/data/extcode/ javascript/jsmath manually. From this reason I report this problem (maybe a bug). What spkg are you talking about? The jsmath-image-fonts one? When you say new Sage, do you mean version 3.4? mabshoff, according to ticket http://trac.sagemath.org/sage_trac/ticket/4674, the updated spkg http://sage.math.washington.edu/home/mabshoff/spkgs/jsmath-image-fonts-1.3p1.spkg was merged into the optional repository. However, it's not listed at http://sagemath.org/packages/optional/ What's going on here? Robert, for now, you can install http://sage.math.washington.edu/home/mabshoff/spkgs/jsmath-image-fonts-1.3p1.spkg into sage 3.4 and it should work. The javascript code was recently reorganized, so that explains the problem (but doesn't explain why the new spkg didn't show up on http://sagemath.org/packages/optional/ ) R question: there are two directories with jsmath.js file: data/ extcode/javascript and local/notebook/javascript. Why? How to find out, which one is used in notebook. The local/notebook/javascript one should be the only one used.

[sage-support] Images in TinyMCE
Dear Support, (Well, probably dear Jason... :) but posted here for others who might ask it in the future) I have tried unsuccessfully on more than one occasion to insert images in the notebook using TinyMCE. I've tried ~/filename, file:///filepath/filename, and I don't know what else. Do I have to upload to the Data directory first, or just the worksheet directory? That seems counterintuitive, given the interface to the icon for it. I got some error messages which suggested that it was looking in the worksheet or cell's individual folder, though, which I am unfortunately not able to copy here now. Specific step-by-step instructions that worked for someone should be sufficient for me to figure it out, I hope.
