machine learning - Encog - Error saving network weights, Not a valid EG file -

i've got network trained , want save , able load later don't have re-train it... duh.

end of training code:

 //save network  serializeobject.save(new file("encognet"),network);  encog.getinstance().shutdown(); 

loading file

basicnetwork network = (basicnetwork) encogdirectorypersistence.loadobject(new file("encognet")); 

i error

exception in thread "main" org.encog.persist.persisterror: not valid eg file.

can tell me how fix this?

i think problem not saving file .eg extension. if not problem, i'm not sure serializeobject.save, know encogdirectorypersistence works me.

so, test out code saving

    public static final string filename = "test_load_net.eg";     encogdirectorypersistence.saveobject(new file(filename), network); 

and load this

    public static final string filename = "test_load_net.eg";      basicnetwork network = (basicnetwork)encogdirectorypersistence.loadobject(new file(filename));
