Hello All,

I am a undergrad at the University of British Columbia and I am
working on Neural Networks. I am trying to get FANN 2.1.0 working on
my Ubuntu Linux OS. I installed the basic FANN component, but I am
having trouble installing the 'Python part.' I am attempting to
install from terminal but I get an error when trying the various
install methods (I was hoping someone might be able to offer some tips
on how to get around this issue):

***@mattmarq-laptop:~/FANN/python$ sudo make

and the output is:

Running SWIG before: swig -c++ -python pyfann/pyfann.i
sh: swig: not found

Matthew,

Looks like you do not have swig or its not in your path.

sh: swig: not found

This should be a simple fix. http://www.swig.org/

You need it to generate the wrappers for fann... pyfann_wrap.cxx

On ubuntu just

# sudo apt-get install swig

also make sure you have the latest beta or cvs version of fann.
