I am trying to run audio classification model on Android device, but I am getting error:
RuntimeError: fft: ATen not compiled with MKL support, it’s caused by MelSpectrogram transformation.
I found few related issues on GitHub:

torchaudio mobile? · Issue #408 · pytorch/audio · GitHub 13
Add SpectralOps CPU implementation for ARM/PowerPC processors (where MKL is not available) · Issue #41592 · pytorch/pytorch · GitHub 10

But neither of them had clear solution. What is proper way to fix this problem, preferably with minimal changes to model.
