SymPy printing in the ipython notebook

Richard Johns
If I open a new notebook and carry out the steps below the output is mathematically correct but it isn't displayed in latex/mathjax format:
from IPython.display import display

from sympy.interactive import printing
printing.init_printing()

from __future__ import division
import sympy as sym
from sympy import *
x, y, z = symbols("x y z")
k, m, n = symbols("k m n", integer=True)
f, g, h = map(Function, 'fgh')

Rational(3,2)*pi + exp(I*x) / (x**2 + y)

The output is:

3*pi/2 + exp(I*x)/(x**2 + y)
 
SoftwareVersion
Python2.7.3 (default, Feb 27 2014, 20:00:17) [GCC 4.6.3]
IPython2.0.0
OSposix [linux2]
numpy1.6.1
matplotlib 1.1.1rc
scipy0.9.0
Thu Apr 03 00:02:41 2014 MST

If I open a terminal in the same directory and repeat these steps the output is displayed in a pretty printing format:

rj@rjslptp:~$ ipython
Python 2.7.3 (default, Feb 27 2014, 20:00:17)
Type "copyright", "credits" or "license" for more information.

In [8]: k, m, n = symbols("k m n", integer=True)

In [9]: f, g, h = map(Function, 'fgh')

In [10]: Rational(3,2)*pi + exp(I*x) / (x**2 + y)
        ⅈ⋅x
3⋅π    ℯ   
─── + ──────
 2     2   
      x  + y

I imagine I'm missing something simple but I haven't been able to figure out what it is. Any help would be appreciated.

Re: SymPy printing in the ipython notebook

Jason Moore
Hi Richard,

I don't think SymPy has tested with IPython 2.0 yet. It is possible that the printing is no broken... It should display in mathjax/latex by default in the notebook and pretty print in the terminal.

If you don't mind please submit an issue on github to the main sympy repository.

Re: [sympy] Re: SymPy printing in the ipython notebook

Richard Johns
Hi Ondrej:

I assumed that SymPy worked with 2.0 since the example notebook included this at the bottom of the page:

nbviewer version: 4c2edac (Mon, 31 Mar 2014 09:14:05 -0500)

IPython version: 2.0.0-dev ( 65651b5 )

Rendered on: Mon, 31 Mar 2014 18:26:32 UTC


I originally tried to do this, with no success, by installing 2.0.0-dev when it didn't work with my old ipython.



My SymPy version is:

In [14]: sym.__version__
0.7.1.rc1

Richard

The latest version of SymPy is 0.7.5. Maybe you just need to upgrade?

Re: [sympy] Re: SymPy printing in the ipython notebook

Yes, definitely upgrade. The 0.7.1 was released 3 years ago, so I am
not surprised it doesn't work.

Re: [sympy] Re: SymPy printing in the ipython notebook

Richard Johns
Yes that was the problem. I should have thought of that myself, however; it would have been nice if the example web page had used something like:

 %load_ext version_information
%version_information numpy, matplotlib, scipy, sympy

Thanks for the help.

Re: [sympy] Re: SymPy printing in the ipython notebook

Aaron Meurer
Yes, at some point IPython stopped working and we had to fix it (either they changed their API or SymPy was using non-public APIs, I don't remember which). But it should work with the latest version. If you run into any more issues with the latest versions of IPython and SymPy, be sure to let us know.

Re: [sympy] Re: SymPy printing in the ipython notebook

Richard Johns
Thanks Aaron, will do.

When I was upgrading to 7.5 I noticed that the documentation said:

'After the download is complete, you should have a folder called “sympy”. From your favorite command line terminal, change directory into that folder and execute the following:'

The folder should actually be 'sympy-0.7.5'.

Also, clicking on the downloads link leads to a message saying that the downloads have moved to github. Wouldn't it be more efficient to just link the new location directly to

https://github.com/sympy/sympy/releases

Thanks again for the great software.
Richard

Thanks Aaron, will do.

When I was upgrading to 7.5 I noticed that the documentation said:

'After the download is complete, you should have a folder called “sympy”. From your favorite command line terminal, change directory into that folder and execute the following:'

The folder should actually be 'sympy-0.7.5'.

Hmm, this is unintentional. I will take a look at this the next time I do a release.
 

Also, clicking on the downloads link leads to a message saying that the downloads have moved to github. Wouldn't it be more efficient to just link the new location directly to

https://github.com/sympy/sympy/releases

Thanks for pointing that out. I fixed it at https://github.com/sympy/sympy/pull/7367.

Thanks again for the great software.

Yes, at some point IPython stopped working and we had to fix it (either they changed their API or SymPy was using non-public APIs, I don't remember which). But it should work with the latest version. If you run into any more issues with the latest versions of IPython and SymPy, be sure to let us know.

Yes that was the problem. I should have thought of that myself, however; it would have been nice if the example web page had used something like:

 %load_ext version_information
%version_information numpy, matplotlib, scipy, sympy

Thanks for the help.

Yes, definitely upgrade. The 0.7.1 was released 3 years ago, so I am
not surprised it doesn't work.
