I have successfully ran the trainer. / when I go to backtest - it fails.
Actually on closer inspection - I can see a bug. saving doesn't recognize tensor shape.
Tensor("output:0", shape=(?, 1), dtype=float32)

which version of tensorflow are you using?

python driver.py -t feedforward

hey @johndpope sorry for a late reply. There were some small issue with the earlier version of the software, but I've just pushed a big update, so it should work correctly now.
