Re: [sage-support] 6.9rc3 : Ipython notebook seems seriously out of whack.

2015-10-12 Thread Emmanuel Charpentier 
I went back o the "develop" branch", fetched the last release (6.9) and 
re-made. $SAGE_ROOT/local/lib/libtinfo* is still out of the way.

The resulting system can open a sample sheet created with 6.9rc3, correctly 
solves x^2+1==0 and typesets the output if necessary.

Two bizarreries :


   - Example of typeset output (cut from Jupyter to Google groups) :

In [5]:

solve(x^2+1==0, x)

Out[5]:
[x=(−i),x=i]

 (i. e. \newcommand{\Bold}[1]{\mathbf{#1}}\left[x = \left(-i\right), x = 
i\right]). The "simple" output doesn't have the superfetatory parentheses 
around the -I solution...


   - The mathjax menu seems difficult to reach


ISTR that something analogous has been discussed recently, but can't 
retrieve it at the moment...

HTH,

This has nothing to do with the LaTeX rendering in the jupyter notebook: it 
results from sage command latex and is already here in the console:

sage: latex([x == -I, x == I])
\left[x = \left(-i\right), x = i\right]

Have you tried to right-click on the displayed formula ? (it works for me)

Works for me in a new sheet. Doesn't in a sheet initially created by

And #19374 still doesn't work for me neither in the "old" or the "new"

Works fine for me with the just released sage 6.9 (which includes #19374). 

- System: Ubuntu 14.04 LTS 64bits with libssl-dev package installed
- Installation of sage 6.9 and launch of Jupyter notebook:
git clone git://github.com/sagemath/sage.git
cd sage
make
./sage -n jupyter

Re: [sage-support] 6.9rc3 : Ipython notebook seems seriously out of whack.

2015-10-11 Thread HG 
I did the same with sage 6.9 and sagemanifold, some command are working 
other not.
I got this message if I try a worksheet done :

Failed to retrieve MathJax from '../nbextensions/mathjax/MathJax.js'

Math/LaTeX rendering will be disabled.

If you have administrative access to the notebook server and a working 
internet connection, you can install a local copy of MathJax for offline 
use with the following command on the server at a Python or Jupyter prompt:

>>> from Jupyter.external import mathjax; mathjax.install_mathjax()

This will try to install MathJax into the Jupyter source directory.

If Jupyter is installed to a location that requires administrative 
privileges to write, you will need to make this call as an administrator, 
via 'sudo'.

When you start the notebook server, you can instruct it to disable MathJax 
support altogether:

$ ipython notebook --no-mathjax

which will prevent this dialog from appearing.


Used from git with a new worksheet some commands works

But not very stable at the moment

ubuntu 14.04 fresh install with git sage and sagemanifold


regards

Henri

Probably there is something wrong with your installation. Did you run 
"make"?

[sage-support] 6.9rc3 : Ipython notebook seems seriously out of whack.

2015-10-10 Thread Emmanuel Charpentier 
I just found another nice one with 6.9rc3.

Not only it has problems with $SAGE_ROOT/local/lib/libtinfo* (see here 
), but it 
also spews nonsense :
In [2]:
%display simple

solve(x^2+1==0,x,to_poly_solve="force")
Out[2]:

[]


Huh ?

Command-line sage :
sage: solve(x^2+1==0, x)
[x == -I, x == I]

Sage via emacs :
sage: solve(x^2+1==0,x)
[x == -I, x == I]

This is nicely typeset in the emacs window, BTW...).

I also checked that the sage notebook is indemn of this folly...

And, BTW, I also tried Trac#19374  
with the same result (and no typeset output, by the way !).

I think this should be a blocker...

For the record : this is on a tree resulting from a fresh tarball, where I 
moved $SAGE_ROOT/local/lib/libtinfo* out of the way, which passes 
ptestlong, and where I did git trac chechout 19374.
 
Any idea/opinion on how to write the ticket ?

HTH,

Huh ?

Works for me...

In any case, it would be very unlikely that a Sage command actually
gives different output in the command line and in the Jupyter notebook.



>jupyter notebook

This works for me too.
