I can't find train.sh

[IvanEvan]

As I said, this project looks like lose the file "train.sh", can anyone help me?
BTW, I wonder how spectrogram worked. I think as follew:
#1. create all wave data's spectrogram image
#2. use CNN classify spectrogram images
It's all right?And which file I need run for achieve #1、#2.
Many thanks in advance~
