This comes from the qs JavaScript library. I'm not really sure how this impacts PyTorch, but it must be present in one of our build inputs or outputs?

Comment 2 Alexander Lent 2026-04-13 01:14:33 UTC
I'm closing with the view that while this may be present in build inputs, as far as I am aware this JavaScript Library does not appear in the Python code or compiled objects output by our build process.
