When I ran the train.py file, I encountered a problem, I hope you can answer it. Thank you.

It seems a problem with scipy or data.
We use scipy==1.4.1. You can try to load the data with the minimal code:

import scipy.io as sio
data = sio.io.loadmat('data.mat', squeeze_me=True, struct_as_record=False)['data']
print(len(data)) # a data list

If it fails, please check if the data are correctly extracted.
For the Network/data/data_train.mat, it has a size of 93,586,704 bytes.
