I have not come across people using Windows or Mac OS X who reported such problems with Sage. So my guess is that you're using a Linux distribution. But which distribution of Linux? If you're using Ubuntu, then, yes, people have reported such problems with Sage binaries for Ubuntu. In that case, some people have had success in using a Debian binary of Sage under Ubuntu, so you might want to try using a Debian binary of Sage under Ubuntu. Another option is to compile Sage from source. Having said that, it's difficult to diagnose the technical issues you're having without knowing the operating system you are using. -- Regards Minh Van Nguyen --~--~-~--~~~---~--~~ 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 -~--~~~~--~~--~--~---

You should be able to get away with rebuilding the two components of Sage that are likely to have these "illegal instructions", namely mpir and atlas. Try the following: - Go to the directory you installed Sage in - Type ./sage -f mpir-1.2.p4 - Wait till MPIR is compiled & installed, then type ./sage -f atlas-3.8.3.p5 If you haven't already remove the file that keeps the flags for the binary you downloaded: rm local/lib/sage-flags.txt Sage should now start without problems.

[sage-support] question about using Sage with Pydev
Hi, I've been trying to get Sage to work with Eclipse/Pydev. From what
I've been able to find online, I've done the following.
-importing "$SAGE_ROOT/devel/sage-main/" to the
project>properties>external source folders
-running either "sage -sh" or "source local/bin/sage-env" from
$SAGE_ROOT
-entering the following code at the start of my python file
import sys
import os
os.environ.__setitem__('SAGE_ROOT', '/home/ggdhines/sage-4.1-linux-
Ubuntu_9.04-i686-Linux')
os.environ.__setitem__('PATH', os.environ.__getitem__('SAGE_ROOT') +
':' + os.environ.__getitem__('PATH'))
os.environ.__setitem__('LD_LIBRARY_PATH', os.environ.__getitem__
('SAGE_ROOT')+'/local/lib')
from sage.all import *
However, when I try running the program from inside Eclipse, I get the
following error:
ImportError: No module named twisted.persisted.styles
If I comment out that import line, I just get an error for the next
import statement (so its not anything specific about twisted).
Any ideas?
thanks, Greg

[sage-support] Sage and medical imaging (i.e. pynifti)
Will it be possible to incorporate access to NIfTI and ANALYZE files
in SAGE through PyNIfTI (http://niftilib.sourceforge.net/pynifti/)?
SAGE (with NumPy and SciPy) could then be a powerful environment for
medical image analysis (much like MATLAB ...).
(i) How should one proceed to get the functionality of - sage:
import nifti
{ without problems with $SAGE_HOME/local/lib/python2.6/site-packages/
nifti/_clib.so, 2): Symbol not found: _Xznzclose }?
(ii) Will pynifti be considered for inclusion in say Sage 4.2 ?

Hi, I can't access the sourceforge website right now, but it is "easy" to install additional python packages in sage. They don't need to be included or packaged. Just go into the "sage environment" with "sage - sh" and install the package there. Background: Sage has it's own python and you have to install it there, not system wide python installation. Your actual problem seems to be that additional C/C++ software is missing, it can be installed in the same way. And, I don't think this will be included in sage, soon. The general process is, to first create an experimental or optional package, that can be downloaded and installed. Once many users need it and after a voting it is included as a standard package.

[sage-support] Singular timeout?
I was asking SAGE to do a calculation that I knew was probably laborious -- I had a plane curve (over Q) and I wanted its genus. I defined it with C=Curve(equation_in_two_variables) and then typed C.genus() after a while (I was in the notebook) I just got the mysterious error message: delaybeforesend: 0 when I expanded it, at the end there was a lot of stuff, but the relevant line was pexpect.TIMEOUT: Timeout exceeded in read_nonblocking(). command: /u/victor/sage/local/bin/Singular So, there are two questions: a) is it possible to give a more informative error message. It seems obvious that singular just took too long in getting back to sage. b) is it possible to give a longer timeout (if I really want the answer)?

The time limit on reading is purposely disabled. Weird. Maybe the subprocess really crashed and the error message is just wrong?Or maybe something is screwy with pexpect. Can you post code?

[sage-support] Re: Singular timeout?
It seems that what I posted about must have been caused by some other error (memory leak?). When I tried to do the same calculation again in the same worksheet, I got a different error about recursion depth being exceeded. So I quit the worksheet and started it over again. This time the calculation completed. Victor On Aug 5, 5:02 pm, VictorMiller wrote: > I had a small typo in the last code.

[sage-support] Re: Sage and medical imaging (i.e. pynifti)
I gave this a shot but it seems its not trivial to install. 1) I installed pymvpa with: pymvpa-0.4.2: sage -python setup.py build_ext 2) I installed the nifti c libraries with: nifticlib-1.1.0: make all 2b) then I copied everything in the bin, lib, and include directories into the corresponding SAGE_LOCAL places. 3) Then I tried to install pynifti but had trouble. Going into a sage shell: pynifti-0.20090303.1: sage -sh building with: pynifti-0.20090303.1: python setup.py build and installing with: pynifti-0.20090303.1: python setup.py install seems to go OK but when I try to test I get an error: pynifti-0.20090303.1: sage -python Python 2.6.2 (r262:71600, Jul 16 2009, 10:01:32) [GCC 4.0.1 (Apple Inc. build 5465)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import nifti Traceback (most recent call last): File "", line 1, in File "nifti/__init__.py", line 21, in from nifti.image import NiftiImage, MemMappedNiftiImage File "nifti/image.py", line 27, in import nifti.clib as ncl ImportError: No module named clib ...I'm not sure how to proceed.

[sage-support] Re: accessing sage notebook with android phone
As Minh, mentioned, you could try a different binary, or just compile from source. Compiling from source isn't too hard, and has the advantage that upgrading to newer versions is faster. It should take roughly 1 hour or so to compile. source for sage-4.1: http://www.sagemath.org/src/sage-4.1.tar (you might want to use a mirror) source installation guide: http://www.sagemath.org/doc/installation/source.html -M.

[sage-support] Re: Sage and medical imaging (i.e. pynifti)
Maybe this was some sort of path issue I don't understand, but when I tried things again it seemed to work, i.e. if I go into my SAGE_ROOT folder and use either sage or the sage python, the "import nifti" works. So what I described above seems to be sufficient, and this could be made into an spkg. I will give that a try tomorrow if I can find the time. -Marshall Hampton On Aug 5, 10:12 pm, William Stein wrote: > On Wed, Aug 5, 2009 at 8:09 PM, Marshall Hampton wrote: > > > > > > > I gave this a shot but it seems its not trivial to install. > > > 1) I installed pymvpa with: > > > pymvpa-0.4.2: sage -python setup.py build_ext > > > 2) I installed the nifti c libraries with: > > > nifticlib-1.1.0: make all > > > 2b) then I copied everything in the bin, lib, and include directories > > into the corresponding SAGE_LOCAL places. > > > 3) Then I tried to install pynifti but had trouble.
