something wrong in wx

I wrote program training na Artificial Neural Network. It work well in
console mode, but when I try to add GUI there is an error:
FANN Error 10: Error reading info from train data file "zapis.txt" , line: 2

There is a code:

I doubt it.
I wrote program training na Artificial Neural Network. It work well in
console mode, but when I try to add GUI there is an error:
FANN Error 10: Error reading info from train data file "zapis.txt" , line: 2

How are you launching the GUI version? Are you double-clicking on an icon
somewhere? Are you sure the application is starting in the correct
directory -- the one that contains zapis.txt?

Perhaps you should try hard-code the full path, or at least doing an
os.chdir().

I launch the Gui version with terminal.
# python Training.py

Yes i'm sure.

it still doesn't work.

Thanks.

Don't know if this will help or not because it seems like a strange
error if this is the problem. I've always had to run my wxPython apps
with pythonw, otherwise it will give you an error saying it needs the
GUI interpreter or something like that. However, this could be an
operating system specific codition. If that doesn't fix anything all I
can say is check and recheck your path.

Sorry to be of no help and to raise another question.
How did you manage to get fann going under python?
I can install fann 1.2.0 allright but something doesn't go with the
python setup.
(I run Python 2.4.1 under linux 2.6.13)
When trying to run a small example in python I always get error
messages about missing definitions in _libfann.
I have read about supposed disultils problems and workarounds, but I
didn't manage yet.
Thank you for any suggestion,
malv
