How can I speed up the training of a network using my GPU?
Unless PyBrain is designed for that, you probably can't.
You might want to try running your trainer under PyPy if you aren't already -- it's significantly faster than CPython for some workloads. Perhaps this is one of those workloads. :)
I was wondering if there is a way to use my GPU to speed up the training of a network in PyBrain.
