[sage-support] Tracking memory usage and time

[J]

Hi,

to do a overview of a rather different set of `SAGE` methods, I would
like to not only track the time used to run a command, but also the
memory usage of the commands.

Is there a recommended way to do this?

Context:
I want to run the `nearestneighbordecoder`, the `syndromedecoder` and
the `informationsetdecoder` for errors from 1 to `X` (where X is
probably

Thanks get_memory_usage sounds good; I want to run several decoders from
the coding theory module to see better show there ups and downs;

it is expected for the syndrome decoder to be quicker but more memory
hungry while the nearest neighbor is more time expensive.

Well, one of the algorithms stores

sum {l^e} {\binom{n}{e}}

with l being the number of elements of the field
which gets big quite fast

More or less this yes;

But it seem I will stick to putting it in a sage ipyhton session wrapped
in a screen session

In detail I found the syndrome_decoders crashes while initiating with
big codes as the system runs out of memory

and that prompted me to plot RAM vs max_error for the syndrome decoder

[sage-support] Issue with Solve

[j wade]

I am having an odd issue with solve in Sage.  I am using Sage 6.3 in Ubuntu 
14.04.

Entering the following commands:

forget()
var('m k c x t')
m=3
assume(4*k*m-c^2==0) 
x=function('x',t)
de = m*diff(x,t,2)+c*diff(x,t)+k*x==0
x=desolve(de,x,ivar=t)
x=x.subs(_K1=0)
x=x.subs(_K2=15)
solve(x(t=(6/c))==1.5,c)

returns [ ].  Now the last equation clearly has an easy solution; the 
equation is 

90*e^(-1)/c == 1.50

If I just enter

solve(90*e^(-1)/c == 1.50, c)

I again get [].

But, if I enter

b=var('b')
solve(90*e^(-1)/b == 1.50, b)

I get the solution:

[b == 60*e^(-1)]

Any idea what is going on here?

Re: [sage-support] Re: OS X 10.12

[J. Friedman]

I downloaded the dmg file, moved the sagemath directory to Applications, then 
double clicked on sage. 
I also tried it through home-brew and also got an error (below). Has anyone 
done a fresh install with an apple running the latest version of OS X?

The easiest thing for me to do was download linux in a virtual box and run it 
sage off Linux, however I can’t connect to the sage server (even though I can 
successfully SSH to the virtual machine). Any suggestions.

This is not supported, and Sage will not work. To install Sage from a
binary package:

1. Open the .tar.bz2 archive (or .dmg on OSX)

2. Move the SageMath folder/app to where you want it to be. You can
   also rename the directory now.

3. Start sage for the first time. This will then automatically patch
   paths in binaries.

After starting Sage for the first time you cannot change the
installation any more. To install Sage elsewhere, start over from the
binary package. Or recompile Sage from scratch in the new location
("make distclean && make")

Re: [sage-support] OS X 10.12

[J. Friedman]

I got it to work.
So I think the problem is python 3, with Anaconda. I logged in under another 
user name that uses Apple’s Python 2. And installed Sage. Then, I can run it 
from my python 3 account. Perhaps your scripts should search out Python 2 when 
there are multiple versions installed.

If anyone else comes across this problem and installing gs and

[sage-support] Simple Combinatorics and Probability

[Matthew J]

Sage is great software that I rave about in pretty much all of my
classes except for probability theory. I’d like to get some info on a
few topics to clear some things up so that I can use these for classes
and to post to an examples worksheet. Thanks in advance to anyone that
replies.

I am wondering how to do a few things.
Is there a better (built-in) way to do simple combinations/
permutations than writing a function like

def choose(n,k): return factorial(n)/(factorial(k)*factorial((n-k)))

or equivalent for permutations?
-

Is there a way to get the Standard Normal CDF other than writing the
function explicitly like below?

def normalCDF(z):
t = var('t')
return N(integrate((1/sqrt(2*pi))*e^((-t^2)/2), t,  -infinity, z))
-

Also, are there any distributions built into sage? I don’t quite know
what working with a distribution symbolically would be like, but as an
example, perhaps being able to do something like
X ~ BIN(n, p) and then get the expected value, variance, or PDF of X?
Assume that n and p are given.

Thanks,

Also for completeness, for permutations I was referring to
permutations without repetitions. Generally calculated as nPr = n!/(n-
r)!

But I suppose this can easily be calculated with binomial(n,r)
*factorial(r)

[sage-support] How to get notebook() help?

[J Elaych]

It takes quite a while to learn how to use the notebook just by
googling around (search google for 'sage %hide' for instance) so I
hope someone can point me in a better direction.

One simple thing I would like to be able to do is to enter a bunch of
forumula's, say integrals or ODEs, at the very beginning of my session
and display them each in nicely formatted latex, as they are entered.
Sort of like a typical maple session, where each equation is typeset
as its entered.  However, the closest I get to such output is to 1)
assign the formula to a variable, 2) assign the latex(forumula) to a
variable, 3) jsmath(this latex variable) and 4) click 'evaluate' under
the cell.

Thats a bit of work and I've found that if I have several jsmath()
displays in a row and hit evaluate, only one of them shows up
typeset.  I know there has to be an easier way and it probably
requires various settings in the dropdown boxes above the worksheet
and some % declares and so on, and I would like to find a good
resource to read about these options.

For instance, the otherwise excellent 'an-invitation-to-sage.pdf'
whitepaper has a nice screenshot of a notebook that seems to do what I
want, with the helpful comment:

---
Here are the commands used to create the output in the Notebook
session
in the above screenshot:
 Sage Notebook
 a,b,c,d,x,y=var(’a,b,c,d,x,y’)
 show(solve(a*xˆ2+b*x+c==0,x))
 show(solve(a*xˆ3+b*x+c==0,x))
 solve(a*x+b*y==0,c*x+d*y==0,x,y)
---

but when I type them in to my notebook cell nothing happens, and when
I click 'evaluate' under the cell I just get an error message.  Also,
I can't tell if the whitepaper's screenshot was generated after each
of these 'show' commands, or if all of the commands are executed at
once via the 'evaluate' button.   Is there, for instance, a mode where
'evaluate' is implicit after each carriage return?

Likewise, searching google for 'sage latex' turns up some interesting
messages, but nothing that helps me set the notebook up to display
formulae.   Another forinstance:  I would like to know how the author
of http://sagenb.com/home/pub/365/  managed to have the nicely latex'd
comments above each of the cells.

I am still playing around and experimenting with the notebook but
there have to be some shortcuts to learning all this, and I'd
appreciate any pointers to websites, archives, and so on.

Thanks,

J

[sage-support] Re: How to get notebook() help?

[J Elaych]

Hi Jose!

Thanks much for that update.  I did read the help on the notebook()
page
and it answered my evaluate-immediately query (Shift-Enter) and I
think
your new worksheet has answered the pretty-text-in-between-cells
question.   From here I think its mostly a matter of trial and error
and experimenting with other people's notebooks.

You're right,  my new first impression of Sage is that it is right on
the cusp of being a real serious competitor to Maple et al, and to
things like Enthought's EPD for a generic math-ready python
distro.   My first first impression on v1 of Sage was that it needed
another commercial package along side it, but now it looks like
Sage will have all of the other capabilities natively.

Thanks again,

J

[sage-support] %latex notebook errors

[J Elaych]

Hi,

I try the following in my first cell in a new notebook with sage-3.4
and the latest Ubuntu 64bit os.


%latex
Try this: $$x^2=-1$$.

evaluate

An error occured.
Error latexing slide.

-
(new cell)
-

Thats all I get.  I don't get any other latex log output, and it
doesn't write any sage*.dvi files.  I've noticed in the sage-support
archives that lots of people have had issues with %latex with output
that began "An error occured" and ended with "Error latexing slide"
but they had lots of other log output to work with.  Also, their
problems were evidently related to some problems with dvipng or other
latex path errors, but my latex and dvi* enviornment seems to be ok,
with all of the programs found in /usr/bin and the like.

Also, if I forget about %latex and the $$ stuff and just select the
'typeset' button and enter 'a+b==0' I get nice formatted output after
evaluate.  (Actually, the nice formatted output reads 'b + a = 0' but
what the heck.)

I've read as much of the docs and help and googled for 'an error
occured' and 'error latexing slide' but I still don't see a
resolution.

Thanks for any suggestions.

Awesome, thanks.   Latex wasn't finding 'fullpage.sty' so I installed
'dblatex' via
Ubuntu, which in turn installed tons of latex packages, including ../
preprint/fullpage.sty.
I see that you have helped other people find fullpage.sty before, but
the real
help for me was the pointer to the sage.misc.latex.Latex().eval()
command.

Thanks again,

[sage-support] Jmol causing Firefox crash

[J Elaych]

I'm using Ubuntu 64 bit on amd2 and running sage-3.4.  I download a
file, "3D graph with points", from sagenb.com and run the cell.  The
interact widgets load and a Jmol splash screen starts and then the
entire browser bails.  Fortunately, I can restart previous session and
recapture my tabs, but of course I have to quickly delete the tab with
the offending worksheet.

Here are the messages from the terminal where I started 'sage -
notebook'.

2009-04-08 21:21:48-0700 [HTTPChannel,60,127.0.0.1]

The money-lines are the "Request error: ..." which is what prints when
the browser dies.  I searched sage-support for that error message but
didn't find it, so here it is for the next person who searches.

Of course, thanks in advance and all.

[sage-support] Re: Jmol causing Firefox crash

[J Elaych]

Thanks for that link.  In fact, the jmol website crashes my Firefox
3.0.8 with all tabs
just like sage did (or jmol did in a sage notebook).

I suspect it may have to do with which/what/how java(s) are installed
on my Ubuntu.

[sage-support] Re: Jmol causing Firefox crash

[J Elaych]

Hi,

Yes that is very useful.  It does in fact appear that the problem
is related to the never-ending problems of 64bit firefox with
64bit plugins.  I won't use 32bit firefox and Sun only has 64bit
java applet plugins for Windows, not for linux.

On Ubuntu, there are two IcedTea plugins for 64bit java
applets --- one works with cacao-oj6-plugin and the other
is standalone --- and the cacao plugin causes firefox to
crash after a few seconds.

The standalone icedtea plugin shows the Jmol splash
screen with the message "Loading Jmol applet" and
an incrementing seconds counter at the bottom.  Mine
is up to 366 seconds, but no applet.

So the issue probably is one for the Jmol people, since
cacao/icedtea has worked for me in the past for
everything except Jmol.

[sage-support] Re: Jmol causing Firefox crash

[J Elaych]

Yes, I went ahead and upgraded to the current Jaunty beta.  Then
I went into synaptic and 1) removed the ia32-sun stuff, 2) did a
"complete removal" of both iced-teas, and 3) installed the
sun-java6-plugin.   Now everything works:  the jmol/atoms demo
and all the jmol sage notebooks.

Now we just need Adobe to get Acroread into 64bits and I can
remove ia32-libs completely, and good riddance it will be.

[sage-support] @parallel() globals problem

[J Elaych]

I don't see many posts about the @parallel decorator, but I'm having
a problem that I would think would be pretty common.  I want to
decorate a function that performs some action with an instantiated
class and returns the results of that class method, but when I try
to execute the generator returned from the decorated function, I get
an
error that the 'global' class cannot be found.

Here's an example:

class foo():
 def do_something(self, myargs):
  return myargs

@parallel()
def f(N):
 a = foo()
 return a.do_something(N)

g=f([1,2,3,4])
list(g)

---
NameError Traceback (most recent call
last)

/home/jlh/ in ()

/usr/local/sage-3.4.1/local/lib/python2.5/site-packages/sage/parallel/
multiprocessing.pyc in parallel_iter(processes, f, inputs)

/usr/local/sage-3.4.1/local/lib/python2.5/site-packages/processing/
pool.pyc in next(self, timeout)

NameError: global name 'foo' is not defined
sage:


So anyway, the only examples I've found of sage + @parallel use
functions that
don't instantiate a user class.  They just use like def f(N):  return
N^2 and so on.
Thanks for any pointers to docs or examples that might help me use
this decorator.

Thanks,

J

[sage-support] Trouble getting sage to find a bit of code I've written.

[J. Cooley]

Firstly, sorry if my questions are stupid; I only started using sage 3
weeks ago.

Okay, I have written a bit of code in my clone in the module
ell_curve_isogeny.py, then I saved and rebuilt my clone to try and
test it in sage. Sage didn't find my function. I went back and saw
that in ell_field.py there had been two other things imported from
ell_curve_isogeny.py, so I added my function on the end, resaved,
rebuilt and tried again, and it still didn't find it. What have I
missed/am doing wrong?

Thanks,
Jenny

[sage-support] Using PyWavelets in Sage

[j wade]

I would like to use PyWavelets (http://www.pybytes.com/pywavelets/) in
Sage.

I am running Sage 4.3.4 on Ubuntu 9.10.

I have installed python-pywt using Synaptic File Manager, but I am not
sure what to do beyond this.  I have refreshed the libraries, and
tried

import scipy
from scipy import pywt

and

import scipy
import pywt

but neither command recognizes pywt.

If someone out there is using pywavelets with Sage, I'd appreciate it
if you could let me know how you were able to get it to work.

[sage-support] Using wavfile.write() in sage generates error message

[j wade]

Hello,

I am attempting to create a .wav file from an array in sage using the
package wavfile.  I am importing a .wav file using the package
wavfile, and then using the python wavelets package 'pywt' to create
the array.  Here are the commands:

import pywt, scipy, numpy
from scipy.io import wavfile
x=wavfile.read('/directory/file.wav')
(cA, cD)=pywt.dwt(x[1],'db1')
xnew=pywt.idwt(cA,cD,'db1')
wavfile.write("noisyholanew.wav",44100, xnew)

The last command generates the following error message:

xnew is the array.  type(xnew) returns .

When I run this series of commands in a python shell, I receive no
error, and a .wav file is generated.

I would like to be able to run this series of commands in sage as
well.

I am using Sage 4.5.3 (compiled from source) and Python 2.6.4 on
Ubuntu 9.10.

Thanks!

[sage-support] Error building Sage: lrcalc-2.1 and python3-3.11.1 failed to build successfully

[Ani J]

### Environment

```markdown
- **OS**:Ubuntu 22.04.4 LTS
- **Sage Version**: sage-10.3
```


### Steps To Reproduce

1. I'm trying to install sage in an anaconda environment in Ubuntu 22.04 
2. I have run the commands './bootstrap', './configure'
3. Then I installed some packages
4. Then I ran 'make reconfigure' followed by 'make'
5. I get the following Error message:

`
***
Error building Sage.

The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):

* package: lrcalc-2.1
  last build time: May 28 13:03
  log file:~/some_path/sage-10.3/logs/pkgs/lrcalc-2.1.log

* package: python3-3.11.1
  last build time: Jun 12 08:30
  log file:~/some_path/sage-10.3/logs/pkgs/python3-3.11.1.log

It is safe to delete any log files and build directories, but they
contain information that is helpful for debugging build problems.
WARNING: If you now run 'make' again, the build directory of the
same version of the package will, by default, be deleted. Set the
environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.

make[1]: *** [Makefile:40: all-start] Error 1
make[1]: Leaving directory '~/some_path/sage-10.3'
make: *** [Makefile:13: all] Error 2
`

### Config log

### Additional Information

No specific references. I wasn't able to find any references for Sage-10.3 
with the same issue.

[sage-support] SageMath 10.3 Qepcad crashed -- automatically restarting

[Ani J]

### Steps To Reproduce

1. I installed Sage-Math 10.3 for my Mac M2 from 
[https://github.com/3-manifolds/Sage_macOS/releases/](link)
2. I tried running a program containing QEPCAD
3. Sage outputs `Qepcad crashed -- automatically restarting`
4. Previously asked about this, but the response was that this is resolved 
in 10.3 [previous 
issue](https://github.com/sagemath/sage/issues/38050#issue-2308818637)
5. The input program is the following: Note that even without 
`memcells='1000 +L5000'` it crashes.

constr21)
print(qepcad(qf.exists(x_0_0,F) ,memcells='1000 +L5000'))
```

### Expected Behavior

It should output the formula the we get after quantifier elimination.

### Actual Behavior

Sage crashes and outputs `Qepcad crashed -- automatically restarting`

[sage-support] More than 4096 characters with Qepcad causes an error

[Ani J]

### Steps To Reproduce

1. I installed Sage-Math 10.3 for my Mac M2 from 
[https://github.com/3-manifolds/Sage_macOS/releases/](https://github.com/sagemath/sage/issues/link)
2. I tried running a program containing QEPCAD. The link for the program: 
[tmp_sage_ani_git_issue.txt](https://github.com/user-attachments/files/16065741/tmp_sage_ani_git_issue.txt)

3. I used the following commands to execute sage: 
```
   mv tmp_sage_ani_git_issue.txt program.sage
   sage program.sage
 ```

### Expected Behavior

It should output the constraints after quantifier elimination.

### Actual Behavior

Gives the following error:
```

[sage-support] QEPCAD Timeout

[Ani J]

 

*Steps To Reproduce*

   1. My machine is Mac M2 with the OS Ventura 13.4 
   2. I already have installed sage with version 10.3 [I believe the same 
   issue exists with 10.4 as well]
   The following program times-out: 

*var('x')*

*var('a')*

*var('y')*

*var('b')*

*var('r')*


*qf = qepcad_formula*

*F0 = (0 > 0 + 1*x*x*a*a + 1*y*y*b*b + -1*a*a*b*b)*

*F1 = (0 > 0 + 1*x*x + 1*y*y + -20*x + -20*y + -1*r*r + 200)*

*F2 = qf.and_(F0,F1)*

*F3 = qf.and_(F2)*

*var("tmp")*

*eliminate_trick = 
qepcad(qf.exists(tmp,qf.and_(tmp==0,F3)),memcells='10 +L5000')*

*print(eliminate_trick)*


Quantification out of the *tmp* variable should be pretty easy since this 
only appears in the constraint *tmp==0*.


*Expected Behavior*

A formula without the tmp variable.


*Actual Behavior*

Just keeps running for a long time.


*Environment*

   - *OS*: Mac M2 with the OS Ventura 13.4 
   - *Sage Version*: 10.3

[sage-support] QEPCAD not working in python package of SageMath

[Ani J]

 

*Also filed this issue on git here: *
https://github.com/sagemath/sage/issues/38779#issue-2568964546

*Steps To Reproduce*

   1. My machine is Mac M2 with the OS Ventura 13.4 
   2. I already have anaconda installed: conda --version prints conda 
   23.10.0 
   3. I used the command conda create -n sage sage python=3.9 to 
   install sage in python as explained in installation guide 
   

 
   4. Then setting the environment using conda activate sage sets the 
   appropriate environment. 
   5. The following program returns an error: 

from sage.all import *

var('a,b,c,d,x,y,z')

qf = qepcad_formula

ellipse = Integer(3)*x**Integer(2) + Integer(2)*x*y + y**Integer(2) - x + y 
- Integer(7)

F = qf.exists(y, ellipse == Integer(0)); F

qepcad(F)


*Expected Behavior:*

*There should be no error and a formula should be returned.*

*Actual Behavior:*

*The error reported is*

[sage-support] how to specify a port when running jupyter notebook

[J E Cremona]

Is it possible to specify which port the jupyter notebook server runs on?
I think the default is , but sometimes a different one is used
(e.g.8889 if  is in use).  I am running on a remote server so that
other users may already be doing something on the default port.  In order
to view the notebooks on my local machine's browser I use ssh-tunnelling
and like to have the port numbers fixed in my ~/.ssh/config file.  This is
awkward if I do not know in advance which port will be used.

[sage-support] Re: recovering the last Sage command while it is still running

[Alex J Best]

At least on my machine opening a new terminal window and starting a new 
sage session then pressing "up" gives me the previous command (still 
running) from the old session.

(I'm on 9.2.beta8 in case that's relevant)

[sage-support] install sage

[Jorge J. Urroz]

I am trying to install Sage 9.2 in Mac book pro, with Catalina. I 
downloaded the sage.app, and when i try to open it, Catalina tells me that 
it can not open it, because it can not verify that it does not have 
malicious code inside.

I am really not good wtih computers, so i would ask for your help with 
this  for really fully beginners.

Thanks in advance.

Jorge

Thanks! Though, what i did is remove the quarantine and give permissions to
sage. Result: it opens the page in a browser and then it says that I do
not have access to the page Jupyter neither SageNB interface.

[sage-support] IPython TextMate Bundle

[Benjamin J. Racine]

I am sending this forward on behalf of Matt Foster...
Be sure to look into pysmell (for completion) as well.
>>

Hi All,

A similar mail has already been on the (ipython) users mailing list, so my 
apologies if you've seen most of this before.

I've started working on a TextMate bundle for IPython, based on the info on the 
Wiki [1], the aim is to produce a BSD licensed bundle which helps to integrate 
TextMate with IPython.

I have set up a project on Github [2] which currently contains:
  * Some help, which doubles as the README
  * commands for running the current file / line / section in IPython (via 
applescript, and Terminal.app)
  * a basic language grammar for ipythonrc config files.

The GitHub page contains the README file which has instructions on how to get 
GetBundles, which will allow you to install the bundle (but not track changes). 
Alternatively, if you have git, you can get the bundle using the following 
commands:

cd "~/Library/Application Support/TextMate/Bundles"
git clone git://github.com/mattfoster/ipython-tmbundle.git IPython.tmbundle 
osascript -e 'tell app "TextMate" to reload bundles'

GitHub users can fork the project and make their own changes.

I'd really love to hear any ideas, suggestions or feature requests people have, 
and I've been told by Fernando that it's ok to use this list for discussions, 
provided we prefix mail subjects with [TextMate].

Thanks,

Matt

[sage-support] Getting sage to see some python libraries that don't appear in the sage library

[Benjamin J. Racine]

Hello all,

I apologize if I am repeating someone, but I figure this question is a big one 
worth bringing up again.  If I want sage to see some publicly available python 
libraries, it seems that I can't just drag and drop them into my 
"site-packages" folder as eggs as I thought I might.  I am on OS X and/or 
Ubuntu and trying to cherry pick from both EPD and Sage.

Thanks,
Ben Racine

[sage-support] Re: How can I make a topographic map with Sage?

[Benjamin J. Racine]

A fellow named Gael Varoquaux uses the topographic map of France as a common 
example for showing off mayavi (a 3D vtk-based viz tool) so this may be more of 
an Enthought Python Distribution question (vs. sage).  Mayavi may be found 
here: http://mayavi.sourceforge.net/ and perhaps elsewhere.  I would just write 
the mayavi list-serve... they are great... and you're likely to get this exact 
example from there.  I might be able to as well, if I remember when I'm on 
other machine.

HTH,
Ben R.

Subject: [sage-support] How can I make a topographic map with Sage?


Is Sage suitable for topography? I have collected the data of a see, discreate 
data points. I need to make regressions on the data. Then, I think the contour 
plot creates the final topographic map. Or am I wrong? How are topographic maps 
dene in Sage? Can I give the data as an input and get the map back as an output?

[sage-support] Multiple plots of a function with different discreet values

[Shawn J. Goff]

I wish to plot I = I0*(exp(q*V/n/k/T)-1) as a function of V for
several different values of n.

I realize I can do something like this:
I1 = I0*(exp(q*V/n[0]/k/T)-1)
I2 = I0*(exp(q*V/n[1]/k/T)-1)
I3 = I0*(exp(q*V/n[2]/k/T)-1)
plot((I1, I2, I3, ...), (V, 0, 1))

But that feels wrong. I'm wondering if there is a better way. For
instance, if it is possible to do something like:
plot(( I(n=n[0]), I(n=n[1]), I(n=n[2]), ...), (V, 0, 1))
I think that would be great. Really, anything better than the example
at the top would be nice.

Thanks for your help.

[sage-support] Limit the range of a plot

[Shawn J. Goff]

I'm trying to plot I = I0*(exp(q*V/n/k/T)-1) as a function of V for
several different values of n. I have:
I = [I0*(exp(q*V/n/k/T)-1) for n in [1, 1.5, 2]]   (thanks, Jason)

If I then say plot(I), it shows one of the lines shooting up to huge
values, and the other two are very small (laying on the abscissa). I
can limit the domain such as plot(I, (V, 0, 1)), but this doesn't help
- it will still accommodate the range for the larger function leaving
the other two looking minuscule. (see output here:
http://shawnjgoff.com/files/sageHelp_largeRange.png )

Looking through the documentation, I found a trick:
show((line(I[0]) + line(I[1]) + line(I[2])), ymin=0, ymax=1, xmin=0,
xmax=2)
This is very close, except for some reason the domain is limited from
0 to 1 even though I have "xmax=2" in there. (see output here:
http://shawnjgoff.com/files/sageHelp_domainLimiting.png )

[sage-support] interrupting execution from the command line

[Charles J. Daniels]

I haven't gotten notebook running just yet, but I prefer command line
anyway so far. The thing is, my computational eyes are larger than my
processing ability's stomach, so I end up finding out it's going to
take longer than I want to complete a command. How do I stop it from
the command line? I tried ctrl-c but no help. I end up having to close
out the command window. In case it matters, I'm running sage via
virtualbox on windows. I've search all over for this info but cannot
find it. Thanks for any help.

You are right, ctrl-c is working. My problem was due to virtualbox
(see, I thought that might matter =) - the right ctrl key is (by
default) used to redirect to your os, so alt-tab will cycle through
your native machice windows rather than the virtual, etc. It was
eating up my ctrl-c, so now I found I can use the left ctrl+c. Thanks
for the help! I wouldn't have thought to try that had you not ensured
me the key combo should work.

If you are running VirtualBox version 3.1.0, which appliance are you
importing? A newer one was exported fairly recently to correct a
problem that occurred during importing. The MD5 checksum of the zip
you downloaded should be b13de836ea5541ba34bca03310a5d265. The name of
the new zip file I downloaded was sage-virtualbox-4.2.1.p1.zip, and
the older one that didn't work for me lacked the p1 towards the end.
To determine the checksum of my downloaded zip I had to download a
freeware app. I winded up with the one at http://www.irnis.net/soft/xcsc/,
if that helps.

To be fair to your efforts William, I'm not sure they have the new
appliance you exported that fixed the "only 2 drives out of 3" error
-- at least fixed it in my case on WinXPPro SP3 in VirtualBox 3.1.0.
Perhaps the only 'bug' is a backward incompatability that breaks
importing certain appliances exported from pervious versions of
VirtualBox.

[sage-support] Get an error message when trying to install sage cell server

I am interested in contributing to the sage cell server and am going through

get the following error message that is detailed below. I am running this on a

another way to achieve this? Can I just download and unzip the archive? If this 
is the case, where do I unzip it to? Any insight as to what the issue might be 
is greatly appreciated, thanks!

Hmmm... I can't figure out how to set up the SSH settings.  Sorry if this 
sound naïve, but what should I put for the host and username?  This is the

So I thought I had ssh installed but apparently not.  The two commands leif 
gave got rid of the ssl.py error but now I am getting a different one:

Can you tell me if this config will work (modified lines below)?  I'm still 
not sure if I have the correct values.

My thinking is that it has to do with what I'm putting for the username in 
the config.py file.  What should I put?  I've tried "aaronej@localhost", 
localhost and simply "" to no success.  Leaving it as None does not work 
either.

[sage-support] View dynamic Sage tutorial from local program

[J. R. L.]

I'm trying to view the "dynamic" (not static) version of the Sage tutorial from 
my locally started instance of Sage. I'm running version 5.13 on Windows 7 
(through VirtualBox), and whenever I click "Help", I can view the static 
version, but the link for the interactive tutorial only returns a dead page. I 
know I can do this online, but is there a way to access this from my copy of 
Sage? Thanks!

[sage-support] building from source: setuptools says "Function not implemented"

[j . d . cranch]

I am attempting to build SAGE 6.2 from source on a cluster running 
Scientific Linux (a Red Hat derivative; kernel 2.6.32-431.1.2.el6.x86_64). 
The CPU was (I'm fairly sure) an AMD Opteron 2218 HE. My build effort 
failed while trying to build setuptools, giving a somewhat taciturn error 
message. I've attached the log file that was generated. The apparently most 
relevant exerpt is:


creating 'dist/setuptools-2.0.1-py2.7.egg' and adding 
'build/bdist.linux-x86_64
/egg' to it
removing 'build/bdist.linux-x86_64/egg' (and everything under it)
Processing setuptools-2.0.1-py2.7.egg
Copying setuptools-2.0.1-py2.7.egg to 
/mnt/fastdata/sm4jdc/sage/sage-6.2/local/
lib/python2.7/site-packages
Adding setuptools 2.0.1 to easy-install.pth file
error: Function not implemented

I have searched the web for this error message and surrounding text, but 
didn't find anything helpful. All advice welcome; I'm only a grunt on the 
machine, but the superuser is friendly and between us we should be able to 
implement any suggestions.

setuptools-2.0.1.p0.log
Description: Binary data

[sage-support] Re: building from source: setuptools says "Function not implemented"

[j . d . cranch]

Thanks for the replies!

I had already had some file system troubles when I tried building on the 
cluster's nfs store. The problem there had to do with "cp -p" not 
preserving permissions. So I was building on the cluster's other network 
file storage, which uses lustre (which I know next to nothing about), and 
had got significantly further by doing so.

As you suggested, I tried building on a node's local disk and then copying 
to NFS. This worked like a charm! I appreciate the help.

This is what I am trying to do.  Using Windows 7 AMD64.

My installation fails because it is unable to "make".

A Grade I introduction for Windows would be very helpful.

Any pointers would be appreciated.

[sage-support] weird inequality bug...

[J. Maurice Rojas]

Dear Sage Gurus,

I was playing with Sage and discovered what appears to be a
really weird bug with Sage's checking of inequalities.

In the attached code, I generate some random 2x2 linear equations
with integer coefficients, and I try to find the minimum and maximum
coordinates of the resulting solutions.  However, somehow, the maxima
are computed but the minima are not.

   In particular, when I run the attached code on my machine, I get (random)
values of x[0] and maxx with x[0]<=maxx (as expected). However,
minx and miny always (incorrectly) remain at +Infinity, even though
x[0] is always less than minx!

   I am a newcomer to Sage so I apologize if I've missed something
dumb. But as of this moment, I'm completely stumped as to why my
simple program is behaving so strangely.

   Hope to hear from you soon.

 Best Wishes,

 Maurice

P.S.:  I get this bug when running my program on my lenovo X201s
laptop, running
 Ubuntu LTS 10.04, and Sage Version 4.6.2, Release Date: 2011-02-25 .

[sage-support] Re: "Inappropriate ioctl for device" when displaying number in Jupyter notebook

Indeed that should fix it, in the meantime you can run something like

sage: from sage.typeset.ascii_art import AsciiArt
