Different data_gen_train in different eporchs

[yianzhongguo]

@FabianIsensee Hi, sir. In the train_network.py when the eporch==100 and epoch==175 the data_gen_train is different generated form create_data_gen_train with different parameters. Why this happend? Thank you!

Please read the paper carefully: "Whenever possible, we initialize these techniques using aggressive parameters that we subsequently attenuate over the course of the training." Data augmentation is made to be less aggressive at some point
