post() function for class analysis

[braveheartwithlove]

@jefflai108 Hi Jeff, Is that right that the post() function in main.py only targets for Multi-class analysis. I trained a binary classifier and use this to do the post analysis, by changing "binary_class=true" in the following code. The results seem skewed (only recognizing for one category) and not right.
Thanks!

Data loading code (class analysis for multi-class classification only)

train_data = SpoofDatsetSystemID(data_files['train_scp'], data_files['train_utt2index'], binary_class=False)
