(All downloads)

Download

SymPy is packaged for the following systems below, so if you use one of them, simply follow the instructions. Otherwise (or if you prefer), you can install the sources directly.

Sources

The only prerequisite is python 2.4 or newer. SymPy optionally uses some other modules or packages, but they are optional. If you have problems using it on a pure Python installation, please report the problems into the Issues and we'll fix that.

latest release

Download the latest tar.gz (something like sympy-0.4.0.tar.gz) from the Featured Downloads on the front page.

On unix systems (linux, BSD, Mac OS X, cygwin, etc.): extract it with the command "tar xzf sympy-0.4.0.tar.gz" and follow the README located in the sympy directory.

You can also download it from the Python Package Index: http://pypi.python.org/pypi/sympy/

previous releases

You can access all the previous (and other) downloads from Downloads.

This is useful if the latest release doesn't work for you for some reason.

git version

To get the git repository, use:

git clone git://git.sympy.org/sympy.git

And you can also access it on the web:

http://git.sympy.org/?p=sympy.git

where (besides other things) you can download any revision you want as a gz, bz2 or zip file. For example, you can download the latest SymPy snapshot here:

http://git.sympy.org/?p=sympy.git;a=snapshot;h=HEAD;sf=tgz

Packages

Debian

SymPy is in Debian Lenny and later. The exact SymPy versions in Debian can be seen here: http://packages.debian.org/python-sympy

So just add the unstable (or testing) among your sources and

apt-get install python-sympy

Ubuntu

SymPy is in all version starting from Gutsy. The exact SymPy versions in Ubuntu can be seen here: https://launchpad.net/ubuntu/+source/sympy

Gentoo

SymPy is available in the portage tree. To install SymPy issue:

emerge -av dev-python/sympy

You can also install SymPy from sunrise overlay.

To setup this overlay, issue:

emerge -va layman
echo "source /usr/portage/local/layman/make.conf" >> /etc/make.conf
layman -f -a sunrise

You can then regularly update to the latest reviewed revision:

layman -s sunrise

All packages in the sunrise overlay are considered unstable, so:

echo "sci-libs/sympy ~x86" >> /etc/portage/package.keywords

Then you can install SymPy as any other package:

emerge -av sci-libs/sympy

openSUSE

You can get it using the Build Service: http://software.opensuse.org/search?q=sympy or using zypper:

zypper ar http://download.opensuse.org/repositories/science/openSUSE_11.0/science.repo
zypper in python-sympy

SAGE

SymPy is in SAGE 2.7 and later. The exact version of SymPy in SAGE can be seen here: http://www.sagemath.org/packages/standard

Windows

Download the windows installer from the frontpage (Featured Downloads) and execute it. There is one known issue with missing MSVCR71.dll, but SymPy works fine.

Installation

Either use the usual:

python setup.py install

or just go to the unpacked directory and use it directly (without installation):

$ python
Python 2.4.4 (#2, Aug 16 2007, 02:03:40) 
[GCC 4.1.3 20070812 (prerelease) (Debian 4.1.2-15)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sympy
>>> 

If it is possible for you, we suggest you use isympy:

$ bin/isympy 
Python 2.4.4 console for SymPy 0.5.8-hg. These commands were executed:
>>> from __future__ import division
>>> from sympy import *
>>> x, y, z = symbols('xyz')
>>> k, m, n = symbols('kmn', integer=True)
>>> f = Function("f")
>>> Basic.set_repr_level(2)     # pretty print output; Use "1" for python output
>>> pprint_try_use_unicode()    # use unicode pretty print when available


In [1]: integrate(x*sin(x), x)
Out[1]: -x*cos(x) + sin(x)

In [2]: Integral(x**2 * sin(x), x)
Out[2]: 
⌠             
⎮  2          
⎮ x *sin(x) dx
⌡             

Test it

Test that SymPy works:

>>> from sympy import Symbol, cos
>>> x = Symbol('x')
>>> e = 1/cos(x)
>>> print e.series(x, 0, 10)
1 + (1/2)*x**2 + (5/24)*x**4 + (61/720)*x**6 + (277/8064)*x**8 + O(x**10)

To test the whole SymPy package, run ./setup.py test in the sympy directory. Note: you only need the standard Python 2.4 (or newer) to run all tests. If it doesn't work, please report the problem into the Issues.
