ZeroDivisionError: float division by zero

[flassTer]

Hello, NVIDIA, I have constructed my own dataset the same way you constructed LibriSpeech. I have tried to start training on this dataset, the reading of the csv file is okay, but then I get this error shown in the picture I uploaded in the link below. Do you know what is causing this? Thanks.

UPDATE: If it makes a difference I am trying to train a model from scratch using DS2, and I have added to the vocabulary the symbols '?', '!' '.', '%'

Can you please upload the full log (preferably as a text)? Do you use the latest master branch? Currently, it looks like there is a division by zero (n_window_stride) in speech_utils.py, line 450. n_window_stride = int(sample_rate * window_stride). So either sample_rate == 0 (something wrong with an audio file?) or window_stride == 0 (have you redefined it in the config file?). Or maybe there is another problem which we can't see from the log's excerpt.

Hey @vsl9 , I have attached the output below:

[vsl9]

Thanks for the log. I don't see anything bad except the message:

File "/mnt/OpenSeq2Seq/open_seq2seq/data/speech2text/speech_utils.py", line 450, in get_speech_features_psf
(1.0 * signal.shape[0] - n_window_size) / n_window_stride

ZeroDivisionError: float division by zero

As I mentioned earlier, n_window_stride = int(sample_rate * window_stride). Can you please use either print or pdb.set_trace to see values of sample_rate (should be 16000) and window_stride (should be 10e-3) variables before the line 450 (for example, at line 447)?

[flassTer]

Okay, I will try to do that and update the issue. thank you.

@vsl9 , it seems that it detects sample_freq: 2 and window_stride: 0.01. What may be the cause of this?

[blisc]

Are you sure that sample_freq is correct? If so, it seems very likely that some files in your dataset is correct.
