The error when run speaker_id.py

[BLack-yzf]

1. hello，Mr.mravanelli
   I have run the speaker_id.py, but i got this error. I have checked the code in line 52. I have found that one of the signal's "snt_len" in the batchsize is “2470” ,therefore the value of "snt_len-wlen-1" is negtive which causes this error. I look forward to your answer and thank you very much!

Traceback (most recent call last):

I found more details. Is there any chance the prepared data is not exactly right? Hope you can reply. Thanks.
