I get this segmentation fault too - but when I run the example in this one I don't, so not sure what could be causing it. https://github.com/bigohstudios/tictactoe

Did you ever get it working? Or with another project?

[Kevin Watt]

Aah, all your inputs and outputs need to be normalized to 0..1 FYI, which may be part of your problem. I'm doing that though and still getting a segfault...

[Большов Андрей]

I think solutions for this kind of bugs is put results in array

results = raw_input[1..-1].map{ |r| r[1] } # error
results = raw_input[1..-1].map{ |r| [r[1]] } # no error

I dont test this for logic proof but segfault dont apeared.

[Kevin Watt]

Right, thanks. However I still don't get any meaningful results, have you had any luck with that? It always returns the same result to fann.run([1,2,3,4]) no matter the input.
