set reduction=0.5 to fix the ValueError issue when loading weights

@Rabia-Metis which densenet did you run. I am doing fine with densenet121 on tensorflow 1.3 and keras 2.0.9

@Rabia-Metis It is seems that you have changed the output shape `classes=1000` to `classes=2`. In this case, you cannot load weights directly because the weights have the output shape `classes=1000`....
