How to save and recover PyBrain training?

Question

Is there a way to save and recover a trained Neural Network in PyBrain, so that I don\'t have to retrain it each time I run the script?

Answer 1

NetworkWriter is the way to go. Using Pickle you can't retrain network as Jorg tells.

You need something like this:

from pybrain.tools.shortcuts import buildNetwork
from pybrain.tools.customxml import NetworkWriter
from pybrain.tools.customxml import NetworkReader

net = buildNetwork(4,6,1)

NetworkWriter.writeToFile(net, 'filename.xml')
net = NetworkReader.readFrom('filename.xml')
