"Illegal hardware instruction" on Apple M1 Mac

Archives 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.

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.

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 …
