Torchaudio Installation Jetson Aarch System

🐛 Bug

For the Jetson Series there is already Torch available but Torchaudio isnt.

To Reproduce

Try install from source to an Jetson Device. Steps to reproduce the behavior:

1. Clone repository
2. sudo packaging/build_from_source.sh => Crash of the sh script.

Workaround

This crash is a result of the libraries config.guess that doesnt know the aarch architecture. This can be bypassed by replacing midinstall the config.guess with a more current one like this https://raw.githubusercontent.com/ropensci/git2r/master/tools/config.guess

Replace the ones in those folders => /tmp/torchaudio-deps/lame-3.99.5/config.guess /tmp/torchaudio-deps/libmad-0.15.1b/config.guess

Also Edit the Script sudo packaging/build_from_source.sh to not override those changes again.

Now it should install.

Expected behavior

Normal installation of the required dependencies.

Note that the libsox installed from apt at the moment is 14.4.2+git20190427-2, which is something we do not support as it has an issue with in-memory decoding and causes un-deterministic behavior if you use file-like object for loading data.

Hi @ark626

Thanks for opening the issue and sharing the workaround. I am open to update the dependency installation script to support aarch64, however, CI system we use (CircleCI) does not seem to provide aarch64 environment so we cannot guarantee the successful build all the time. (Although if the issue happens only in dependency it should work) Therefore I will keep this issue open as reference point for future audience who seek instruction for building torchaudio in aarch64.
