"Illegal hardware instruction" on Apple M1 Mac

DeepSpeech
#1

When I run a basic example on a 2020 M1 MacBook Air:

cd ./DeepSpeech-examples/ffmpeg_vad_streaming
npm install
node ./index.js --audio /tmp/deepspeech/audio/2830-3980-0043.wav --model /tmp/deepspeech/deepspeech-0.9.0-models.pbmm

I get the error

zsh: illegal hardware instruction  node ./index.js --audio /tmp/deepspeech/audio/2830-3980-0043.wav --model

I get the same error

  • if I run the example from a Terminal instance booted with Rosetta
  • if I run a different example, e.g. ./nodejs_mic_vad_streaming

Has anyone had any luck running inference on an arm64 Mac, with or without emulation?

ffmpeg: 4.3.1
node: 14.15.3

I don’t have a Mac, so I might be wrong. But you should be able to run it if you emulate a X86 platform. Maybe try to run inference with Python command line client which is bit more talkative with the error messages.

#3

We don’t have support for ARM64 M1 on Mac, and we don’t have hardware, so it’s hard to help and give support as well as any time this can be done.

#4

I don’t know how you can tell macOS to change its platform at runtime, our loading code will use arch-specific paths, so since the system sees this is ARM64, it loads it: https://github.com/mozilla/DeepSpeech/blob/fcbd92d0d75beee36473aa44669fa330ca522cdc/native_client/javascript/index.ts#L5 it is handled by node-pre-gyp

If you inspect the nodejs package:

We only have macOS amd64 binaries there, so if anything is running on your Mac M1, I doubt it’s ARM64 code, but rather translation from amd64. Who knows what can be broken in this case …
