Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/torchaudio) and found it was in an excellent condition.

Hi friend!

We really, really, really appreciate that you have taken the time to make a PR on conda-forge/staged-recipes! conda-forge only exists because people like you donate their time to build and maintain conda recipes for use by the community.

In an effort to maintain this repository and increase the signal-to-noise for open PRs, the maintainers of staged-recipes close excessively old PRs after six months. This PR will remain open for another month, and then will be closed.

If you'd like to keep it open, please comment/push and we will be happy to oblige! Note that very old PRs will likely need to be rebased on main so that they can be rebuilt with the most recent CI scripts. If you have any trouble, or we missed reviewing this PR in the first place (sorry!), feel free to ping the team using a special command in a comment on the PR to get the attention of the staged-recipes team.

Cheers and thank you for contributing to this community effort!

Not stale

@h-vetinari hey another package I'm maintaining is requiring torchaudio now for dependency... You seem to know a lot more about what's going on with this package, do you feel optimistic about this PR?

Hey @thewchan, very sorry for the delay, I had to look for a flat and then move, could not respond to everything in time. I want to revive this PR, especially not that the unix-y parts of kaldi should be solved, we should be able to progress. :)

@h-vetinari thanks very exciting to hear!

I'm probably just not seeing the forest for the trees, but I'm baffled why zlib isn't being found here.

FYI: We cleaned up the third party dependencies on torchaudio nightly.

• No longer statically bind libsox. So sox from conda-forge works as-is.
• libsox integration is built by compiling stub library. This means torchaudio with libsox built can be built without libsox installed in the environment.
• FFmpeg integration is built using pre-compiled FFmpeg binaries as scaffolding.
• C++ bindings to flashlight-text and Kaldi were removed. The build process has been simplified a lot.

Hey @mthrok, thanks a lot, that's amazing news! 🤩

I'll try again as soon as there's a new release!

@h-vetinari looks like the dependency changes are released in 2.1: https://github.com/pytorch/audio/releases/tag/v2.1.0
