Exporting the operator stft to ONNX opset version 9 is not supported.

See original GitHub issue

Hi, I try exporting the process of feature extraction to onnx:

import torch
import torchaudio

model = torchaudio.transforms.MelSpectrogram()
x = torch.randn(1, 16000)
torch.onnx.export(model, x, 'tmp.onnx', input_names=['input'], output_names=['output'])

and get:

RuntimeError: Exporting the operator stft to ONNX opset version 9 is not supported. Please open a bug to request ONNX export support for the missing operator.

So will torchaudio add supports operators used in torchaudio.transforms module in the future? You see that exporting the process of feature extraction and the neural network together will be very convenient.

Thanks!

@chenjiasheng There is actually some good news around : pytorch/pytorch#65666 and onnx/onnx#3741
