Documentation
- start here: http://www.scipy.org/Documentation
- for matlab users: http://www.scipy.org/NumPy_for_Matlab_Users
- very useful are also the cookbook: http://www.scipy.org/Cookbook
- and the example list: http://www.scipy.org/Numpy_Example_List_With_Doc
- the ultimate reference is the guide to NumPy/SciPy by Travis Oliphant http://www.tramy.us/guidetoscipy.html
Installation (Win)
i heard that the easiest way to install all of these packages is from here: http://code.enthought.com/enthon/
Installation (OSX)
see below
Numpy
Python 2.5
you need a more recent version of python than what ships with OSX. install python 2.5 from here: http://macpython.org/packages/py25-fat/ afterwards, you have to make sure that this is the python version that is actually used when you type 'python' in your terminal window. in order to chech that, type 'which python':
% which python /Library/Frameworks/Python.framework/Versions/Current/bin/python
in order to add /usr/local/bin to your path, put the following line into your ~/.cshrc file:
setenv PATH /usr/local/bin:${PATH}
(this is the syntax for the cshell. if you are using the bash, you have to put something like 'export PATH=/usr/local/bin:${PATH}' into your ~/.profile file)
it is useful to add the directory with your python files, say ~/python to your python path: create the following file and add the line '/Users/your_username/python'
vi /Library/Frameworks/Python.framework/Versions/Current/lib/python2.5/site-packages/your_username.pth
Numpy
install numpy from the same web page http://macpython.org/packages/py25-fat/ give it a try by running 'python' and within python run the commands
import numpy numpy.test()
IPython
get ipython from here: http://ipython.scipy.org/dist/ipython-0.8.1.tar.gz
tar xvzf ipython-0.8.1.tar.gz python setup.py install
i recommend to link ipython into your /usr/local/bin directory:
sudo ln -s /Library/Frameworks/Python.framework/Versions/Current/bin/ipython /usr/local/bin
now you should be able to start ipython in a terminal window:
ipython
you can customize ipython (for example the colors) by modifying the file
~/.ipython/ipythonrc
Matplotlib
install matplotlib from http://macpython.org/packages/py25-fat/
you can give it a try by running
ipython -pylab
and within ipython, run a simple plotting command like:
plot(rand(100))
you can customize matplotlib by modifying the file
~/.matplotlib/matplotlibrc
if this file does not exist, you can get a copy here:
mkdir ~/.matplotlib cp /Library/Frameworks/Python.framework/Versions/Current/lib/python2.5/site-packages/matplotlib/mpl-data/matplotlibrc ~/.matplotlib
i recommend to change the following setting:
text.usetex : True
(of course, for it to work, you need to have latex installed)
Qt 3
install Qt 3 using fink:
fink install qt3mac
in order for Qt applications to find the library, you have to set the following environment variable in your startup script (~/.cshrc):
setenv DYLD_FALLBACK_LIBRARY_PATH /sw/lib/qt3mac/lib
sip
get sip here: http://www.riverbankcomputing.com/Downloads/sip4/sip-4.7.1.tar.gz
tar xvzf sip-4.7.1.tar.gz cd sip-4.7.1 python configure.py -n make sudo make install
PyQt 3
get PyQt 3 here: http://www.riverbankcomputing.com/Downloads/PyQt3/GPL/PyQt-mac-gpl-3.17.3.tar.gz
tar xvzf PyQt-mac-gpl-3.17.3 cd PyQt-mac-gpl-3.17.3 python configure.py -w -y qt-mt -q /sw/share/qt3mac
make sure that the qtext module is mentioned as one of the modules that will be built!
make sudo make install
now you have the qt library with python bindings installed. you can change the matplotlib settings to use qt. this way, you won't need x11 any more. just edit ~/.matplotlib/matplotlibrc:
backend : QtAgg
Scipy
the installation of scipy requires that you compile some of the programs yourself.
Developer Tools
you need to install the apple developer tools that ship with OSX. all the following programs have to be compiled with gcc version 4.0
sudo gcc_select 4.0
Fortran
you need the gnu fortran compiler. you can download a binary for the gfortran 4.2.1 from r.research.att.com here: http://r.research.att.com/gfortran-4.2.1.dmg
FFTW Libraries
FFTW are optimized libraries for fast fourier transform. download version 3.1.2 here: http://fftw.org/fftw-3.1.2.tar.gz
tar -xvzf fftw-3.1.2.tar.gz cd fftw-3.1.2 ./configure make sudo make install
Scipy
now you are all set to compile and install scipy. download scipy 0.6.0 here: http://prdownloads.sourceforge.net/scipy/scipy-0.6.0.tar.gz
tar xvzf scipy-0.6.0.tar.gz cd scipy-0.6.0 python setup.py install
afterwards, you should run (within ipython)
import scipy scipy.test()
at the moment, all but 2 tests should run fine. the two remaining tests will be hopefully fixed soon.
