silero usage of `torch.stft`

[vmoens]

It seems that silero uses the torch.stft function in a way that will be deprecated in the next pytorch release.

Previously, the following usage was permitted

torch.stft(tensor, num, num, num, num, bool, bool, *other)

but now a string representing the padding mode must be included

torch.stft(tensor, num, num, num, num, bool, str, bool, *other)

PR presumably responsible of the BC breaking change

Perhaps @peterbell10 can comment on this?

@snakers4 do you think it's something that can be fixed? Because the source code is not shared it's hard for us to debug this properly.

Hi,

Link to the broken CI log

Looks like this is based off a nightly PyTorch build.

Here is how we use torch.stft before converting to TorchScript

class STFT(nn.Module):
    def __init__(self):

....

    def forward(self, x):
        return torch.stft(x,
                          n_fft=self.n_fft,
                          hop_length=self.hop_length,
                          win_length=self.n_fft,
                          return_complex=True,
                          window=torch.hann_window(window_length=self.n_fft,
                                                   dtype=x.dtype, device=x.device)).abs()

but now a string representing the padding mode must be included
pad_mode (string, optional) – controls the padding method used when center is True. Default: "reflect"

Is it already set in stone that this breaking change will be merged as is?
Usually PyTorch does not make such changes.

The following files fail:

• file_path = 'python_code/snakers4_silero-vad_language.py'
• file_path = 'python_code/snakers4_silero-vad_number.py
• file_path = 'python_code/snakers4_silero-models_stt.py

In any case: snakers4_silero-vad_language.py and python_code/snakers4_silero-vad_number.py can be deprecated, because no one uses them and we decided to deprecate them.

As for python_code/snakers4_silero-models_stt.py I can just rebuild and reupload the latest models if the change gets added to a release.

it seems this PR will be reverted so let's wait for a couple of days before acting on anything.

Thanks for your responsiveness!

ok

Our CI seems to be green now: #225 (https://app.circleci.com/pipelines/github/pytorch/hub/1725/workflows/ec0914a3-1510-4dcd-b3b3-42f1eca174cd/jobs/2166)

Thanks a lot @vmoens for investigating, and @snakers4 for your timely replies!

Hope that this minor contribution made PyTorch a bit better)
