[sage-support] Why does Sage Math crash instantly? / Running .sage files?
Hello. First of all, I need to Mention that I am completely new to Sage Math and I have no idea what causes my problem(s), like seriousely, no idea. When I start SageMath, it instantly crashes, I don't even touch anything. I'm running Windows 10 and I downloaded the binaries, a virtual box and this sage-8.6.tar.gz file. I am sure that I must be missing something but I don't know what. Yesterday, I managed to get Sage to work, so in the terminal i could write simple commands like sage:4+3 and later, I reinstalled python. Now it does not work anymore. My original aim was it to have sagetex in Latex, but for some reason running the .sage file which is created with every document using sagetex doesn't do anything and sage does not compile my document. And yes, I did follow the instructions how to make sagetex known to tex. I have no idea how to continue, so many problems and i'm desperately trying to get things to work. (Feel like I downloaded half the Internet...) Thank you very much for any help. -- You received this message because you are subscribed to the Google Groups "sage-support" group.

[sage-support] Re: duplicate legend
Still some work must be done in the Sage plugin. In the meantime, the
following plugin adaptation to the Python's TeXmacs plugin should work in
Linux. I will try to have the Sage plugin be updated in the coming weeks,
but in the meantime you can try this one. Just extract itand put into your
.TeXmacs file inside your plugins directory.
I still need to look into the graphs shown in the plugin.

[sage-support] introduction and help for math calculation online
Hi, My name is Adrian, I'm new here, and I don't have knowledge about Sage. I need somebody who help me understand How can I call to webservice or something similar to calculate maths. Is something like that?, because I need solution to my final project for second degree. I'm thinking about web service to call to him and asking about solution of calculations. I'm preparing my final project in c#/ web app. I think that the bast way could be via web service, but If not, maybe some dll or RSS channel. I don't have idea about Sage and solutions of Sage. Any idea to help me? Additionally I need way to restrict similar calculations e.g. 3+2 and 2+3 . but It's the simplest. But if a calculations will be bigger and dificult, I don't have Idea to restrict them. Some Idea, languages, dlls, parses from c#. Please, help me! I don't have a lot of time now to prepare ma project, so I need you help. Thanks for each response.

[sage-support] Sage 4.8 notebook/server error on OSX and Linux
Hi, I have just tried to move on to v4.8 and I have encountered an error, on both precompiled binaries for OSX 10.6 64bit (running on OSX 10.6.8) and on OpenSuse Linux 64bit (where Sage was compiled from sources, which went OK). The error is as following: on any worksheet, if a click evaluate under a cell, the web browser sends the request to the server, and it waits for it, but it never receives one. Instead Sage outputs the same error several times (appended in the end). If I save close and then reopen the worksheet I now see the result of evaluate under that cell which tells me the issue is in server's response to requests. Sage error output (identical on pre-build binaries for OSX and on compiled from source sage on Suse Linux), repeated several times for one request: 2012-02-17 00:45:11+0200 [HTTPChannel,13,127.0.0.1] Exception rendering: 2012-02-17 00:45:11+0200 [HTTPChannel,13,127.0.0.1] Unhandled Error Traceback (most recent call last): File /data/sys/bin/sagemath.org/sage-4.8/local/lib/python2.6/site-packages/Twisted-9.0.0-py2.6-linux-x86_64.egg/twisted/internet/defer.py, line 625, in gotResult _deferGenerator(g, deferred) File /data/sys/bin/sagemath.org/sage-4.8/local/lib/python2.6/site-packages/Twisted-9.0.0-py2.6-linux-x86_64.egg/twisted/internet/defer.py, line 602, in _deferGenerator deferred.callback(result) File /data/sys/bin/sagemath.org/sage-4.8/local/lib/python2.6/site-packages/Twisted-9.0.0-py2.6-linux-x86_64.egg/twisted/internet/defer.py, line 238, in callback self._startRunCallbacks(result) File /data/sys/bin/sagemath.org/sage-4.8/local/lib/python2.6/site-packages/Twisted-9.0.0-py2.6-linux-x86_64.egg/twisted/internet/defer.py, line 307, in _startRunCallbacks self._runCallbacks() --- exception caught here --- File /data/sys/bin/sagemath.org/sage-4.8/local/lib/python2.6/site-packages/Twisted-9.0.0-py2.6-linux-x86_64.egg/twisted/internet/defer.py, line 323, in _runCallbacks self.result = callback(self.result, *args, **kw) File /data/sys/bin/sagemath.org/sage-4.8/local/lib/python2.6/site-packages/Twisted-9.0.0-py2.6-linux-x86_64.egg/twisted/web2/resource.py, line 230, in lambda ).addCallback(lambda res: self.render(request)) File /data/sys/bin/sagemath.org/sage-4.8/devel/sagenb/sagenb/notebook/twist.py, line 1244, in render notebook.add_to_user_history(H, self.username) File /data/sys/bin/sagemath.org/sage-4.8/devel/sagenb/sagenb/notebook/notebook.py, line 956, in add_to_user_history history = self.user_history(username) File /data/sys/bin/sagemath.org/sage-4.8/devel/sagenb/sagenb/notebook/notebook.py, line 938, in user_history for hunk in self.__storage.load_user_history(username): File /data/sys/bin/sagemath.org/sage-4.8/devel/sagenb/sagenb/storage/filesystem_storage.py, line 251, in load_user_history return self._load(filename) File /data/sys/bin/sagemath.org/sage-4.8/devel/sagenb/sagenb/storage/filesystem_storage.py, line 134, in _load return cPickle.load(open(self._abspath(filename))) exceptions.EOFError: Thank you. -- 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 URL: http://www.sagemath.org
[sage-support] Re: Sage 4.8 notebook/server error on OSX and Linux
As usually, one tries to find the error source several hours and then, after asking for help, one finds it in minutes. The problem was notebooks files got corrupted after a power outage. I've moved the directory to a backup location, recreated it by running Sage and then copied the old files from admin/ directory. All is OK with an empty notebook folder. I'll search the user history to see if I can eliminate the error source.

[sage-support] Re: sage console in ubuntu 10.10 and jmol
Solved! I did sage -sh and then i tried jmol. It said that it could not find the main class because it could not find a directory related to open jvm. I had installed sun-java6, but I checked for the directory. I guess sage found the directory and assumed that I had openjava. The whole thing got solved once I went to Synaptic (not software center) and completely remove all the open java packages as well as the iced tea ones. This did the trick.

[sage-support] Re: Printing a worksheet with plots does not work
I think the problem is my firefox: I could not even print the google page; same problem happened. I have no idea why; I could print some pages with graphics, but not others. The problem is not sage, for sure. I am sorry about the post. Sage is innocent. Adrian.

I ran the notebook with sage -notebook -directory=/home/soto/Dropbox/sagestuff The problem also happens if I run sage online, so probably the problem is in firefox, not in sage.

[sage-support] Re: maximum recursion depth exceeded in cmp
This is a dirty solution, but it might be interesting:
It is possible to implement tail recursion; this would solve the
problem for certain kinds of recursion; but will fail if the call is
not a tail call, and I think this code won't work, but some variations
would...
I toss it as an idea:
The code is taken from http://code.activestate.com/recipes/474088
import sys
class TailRecurseException:
def __init__(self, args, kwargs):
self.args = args
self.kwargs = kwargs
def tail_call_optimized(g):
This function decorates a function with tail call
optimization. It does this by throwing an exception
if it is it's own grandparent, and catching such
exceptions to fake the tail call optimization.
This function fails if the decorated
function recurses in a non-tail context.
def func(*args, **kwargs):
f = sys._getframe()
if f.f_back and f.f_back.f_back \
and f.f_back.f_back.f_code == f.f_code:
raise TailRecurseException(args, kwargs)
else:
while 1:
try:
return g(*args, **kwargs)
except TailRecurseException, e:
args = e.args
kwargs = e.kwargs
func.__doc__ = g.__doc__
return func
@tail_call_optimized
def factorial(n, acc=1):
calculate a factorial
if n == 0:
return acc
return factorial(n-1, n*acc)
print factorial(1)
prints a big, big number,
but doesn't hit the recursion limit.
@tail_call_optimized
def fib(i, current = 0, next = 1):
if i == 0:
return current
else:
return fib(i - 1, next, current + next)
print fib(1)
also prints a big number,
but doesn't hit the recursion limit.
@tail_call_optimized
def say(something):
print something
say(something)
say('hello')
If I remember correctly, this code breaks and hangs the computer if
the tail is not a tail call; but there seems to be other solutions in
http://code.activestate.com/recipes/474088 that solve this problem
I would love if sage included a similar decorator; but am not sure of
the implications.
Another alternative is rewriting your code... to use iterations
instead of recursion whenever possible.
Peace.
-Adri'an.

[sage-support] Re: attach works in command line but not in notebook
I am sorry, I read it wrong; you are indeed giving the full path.
Something I was thinking is that it could be related to what happens,
in addition to what others have commented is:
1) The error is Syntax error not File not found, so maybe the
quotes arround the path would work.
2) The file is in /media/... Does it work with other files in other
directories? With .sage files?
3) Can you attach a file in ~/.sage?
Well, I hope this is fixed. Or just changing the extension, as
Marshal suggested, should work. This would explain the Syntax Error.

[sage-support] showing the answer of solve in the notebook.
If, in the notebook one writes:
a,b,c,d,n=var('a b c d n')
solve([a*d-b*c==1,a*d/(a*d - b*c) - c*(a*n + b)/(a*d - b*c)==1,c*d/
(a*d - b*c) - c*(c*n + d)/(a*d - b*c)==0, a*(c*n + d)/(a*d - b*c) -b*c/
(a*d - b*c)==1],a,b,c,d)
sage does not return anything.
if one does, instead
a,b,c,d,n=var('a b c d n')
r=solve([a*d-b*c==1,a*d/(a*d - b*c) - c*(a*n + b)/(a*d - b*c)==1,c*d/
(a*d - b*c) - c*(c*n + d)/(a*d - b*c)==0, a*(c*n + d)/(a*d - b*c) -b*c/
(a*d - b*c)==1],a,b,c,d)
print(r) #show(r) also works
Then sage does return
[
[a == 1/r14, b == r13, c == 0, d == r14]
]
(The answer has two degrees of freedom...)
This behavior is different than
solve([a*x+b*n==c,c*x+d*n==e],x,n)
which does display the answer without first assigning and then showing
the answer.
In the console, sage has no problem in giving the answer for both.
Thanks, and I think SAGE is a wonderful program.

[sage-support] attaching files that attach other files in the notebook
I have a folder PROGRAMS where I have two files: substitutions.sage and morphisms.sage The first line in substitutions.sage is attach morphisms.sage This works well if I cd into PROGRAMS and then run sage. This way I can do sage: attach substitution.sage and everything works as expected. This is my prefered way to edit files (I edit in Emacs, and everything works fine), and I can move the directory around. However, If I want to use the notebook, it uses by default the directory ~/.sage, and I don't know of a way to change that. I tried changing the value of DIR with no success. I tried giving the complete path, but it always prepends ~/.sage/ to the file morphism.sage. Giving the full path in morphism.sage does not work either, since it prepends ~/.sage/ to the path. I tried changing it using ../../ but this breaks the behavior I want to edit files using a text editor and the console. I guess I can do a symlink into .sage, but I guess there should be a nicer solution. Any ideas?

Yes, people will do dumb things if they are given a chance, but at

I think the order of the i and j is transposed (assuming row i and column j): sage: M = matrix(5,5,[[1/(i+j%2) for j in range(1,6)] for i in range (1,6)]) sage: M [1/2 1 1/2 1 1/2] [1/3 1/2 1/3 1/2 1/3] [1/4 1/3 1/4 1/3 1/4] [1/5 1/4 1/5 1/4 1/5] [1/6 1/5 1/6 1/5 1/6] s M = matrix(5,5,[[1/(i+j%2) for j in range(1,6)] for i in range(1,6)]) On Dec 10, 4:24 pm, David Joyner [EMAIL PROTECTED] wrote: One way to do it (for a 10x10): sage: n = 10 sage: M = Matrix(n,n,[[1/(i+j) for i in range(1,11)] for j in range(1,11)]) sage: M [ 1/2 1/3 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11] [ 1/3 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11 1/12] [ 1/4 1/5 1/6 1/7 1/8 1/9 1/10 1/11 1/12 1/13] [ 1/5 1/6 1/7 1/8 1/9 1/10 1/11 1/12 1/13 1/14] [ 1/6 1/7 1/8 1/9 1/10 1/11 1/12 1/13 1/14 1/15] [ 1/7 1/8 1/9 1/10 1/11 1/12 1/13 1/14 1/15 1/16] [ 1/8 1/9 1/10 1/11 1/12 1/13 1/14 1/15 1/16 1/17] [ 1/9 1/10 1/11 1/12 1/13 1/14 1/15 1/16 1/17 1/18] [1/10 1/11 1/12 1/13 1/14 1/15 1/16 1/17 1/18 1/19] [1/11 1/12 1/13 1/14 1/15 1/16 1/17 1/18 1/19 1/20] On Wed, Dec 10, 2008 at 5:19 PM, Alasdair [EMAIL PROTECTED] wrote: The title pretty much says it all - for example, how would I create a 4x4 matrix whose (i,j)-th element is 1/(i+j)?

[sage-support] Re: sage and tkinter?
I came accross the same thing a while ago. In the post GUI for sage http://groups.google.com/group/sage-support/browse_thread/thread/6cea70d6be0436fa/582b7f836eee9816?lnk=gstq=tk#582b7f836eee9816 , William Stein suggested the following: (1) Make sure you've installed the tk devel package.it's called tk8.4-dev under Ubuntu.(Make sure the tk version is at least 8.3.) (2) Make sure SAGE's Python has Tk support included. It will if you built Python yourself and already had tk8.0-dev installed. Otherwise, you'll have to rebuild the Python interpreter included in SAGE: sage -i sage -f python-2.5.1.p3 Here I got the version number as the latest Python package listed at SAGE_ROOT/spkg/installed. One could also look at http://sagemath.org/packages/standard/ I think the order of the last command is wrong, though, it should be: sage -f -i python-2.5.2.p8 (at least with the latest version of the packages) Hope this helps. -Adrian On Dec 3, 9:11 am, Jaap Spies [EMAIL PROTECTED] wrote: David Joyner wrote: System wide, it works fine: For me it works: -- | Sage Version 3.2.1, Release Date: 2008-12-01 | | Type notebook() for the GUI, and license() for information.| -- sage: import Tkinter sage: import _tkinter sage: Jaap --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

[sage-support] Re: display 3d graphics in TeXmacs sage plugin
sage: var('x,y')
sage: plot3d(sin(x*y),(x,-1,1),(y,-1,1)).show()
This launches jmol, and one is able to rotate the shape. One can also
save the image and then import the saved image into Texmacs
sage: var('x,y')
sage: plot3d(sin(x*y),(x,-1,1),(y,-1,1)).show(viewer='tachyon')
launches a viewer (eog) of a file in format png. one can also save and
then import.
However, the behaviour for 2d plots is nice in that it immediatly
includes it in the text.

Please anyone who knows how this works give some advise or some other

Thetexmacs/sage interface was written by Mike Hansen before
Sage had any 3D plotting, so I suspect it doesn't at all support
it. That said, two questions:
(1) does 2D plotting work?
(2) What happens if you do
sage: var('x,y')
sage: plot3d(sin(x*y),(x,-1,1),(y,-1,1)).show()
(3) What if you do
sage: var('x,y')
sage: plot3d(sin(x*y),(x,-1,1),(y,-1,1)).show(viewer='tachyon')

[sage-support] Re: Bugs in DiGraph ?
I now get it, when I said {1:{1:'hola'}... it understood {1:
{1:list('hola') and hence treated hola as a list.
I don't recall reading that one should input as a list if one selects
multiedges, at least I don't recall seeing an example with that
notation. This is, I think a little bit of a tricky thing, since the
notation works for regular graphs.
At least I know what to do now. But I don't know if the behavior here
is intended. Probably it works like that to have a short way of
entering several edges with one level. Or the authors did not intend
it to work that way, in which case it could be fixed.
One example with that behavior in the documentation would be great.
Thanks a bunch.
-Adrian.

It looks like it is creating an edge for every character in every other
label, which I think is a bug. I've created a ticket to track the
status of this bug:http://trac.sagemath.org/sage_trac/ticket/3928
Thanks for reporting it.
As Robert Miller noted on the ticket, there is nothing wrong going on
here. The correct way to create the graph that you want is:
sage: G=DiGraph({1:{1:['hola','hi'], 2:['two','dos']},2:{1:['one']}},
loops=True, multiedges=True)
sage: G.edges()
[(1, 1, 'hi'), (1, 1, 'hola'), (1, 2, 'dos'), (1, 2, 'two'), (2, 1, 'one')]
