OK this is pretty impressive. Overall it looks reasonable, one thing I don't see is how you tested it though. Did you manually trigger the build job to confirm everything works now? |

The worst hack I've written so far in my life. Github Actions is a (useful) abomination.
Goal: Don't run nightly builds on Python 3.13. We depend on HF Datasets, which depends on PyArrow, who haven't released a Python 3.13 wheel. It is expected to come out soon in version v18. Therefore, Python 3.13 builds break.
Simple enough, right?
WRONG
SO WRONG
UNBELIEVABLY WRONG.
Attempt 1: Figure out a way to make the
buildjob conditional on whether the matrix entry way for Python 3.13. Eight hours later, it's pretty clear that this isn't possible (through torchtune) b/c thebuildjob is controlled by dev-infra and we just pass in the entire matrix and it handles the actual execution.Attempt 2: Filter the matrix generated by the
generate-matrixjob to remove all Python 3.13 entries. It was about three hours in that I figured out I could create a Python shell in the filtering job. This sped things up and after another couple hours, here we are. But, Joe, how do you know it works if Python 3.13 jobs are only kicked off for nightly builds and you've done all your testing on this PR? I toggled the filtering function to exclude Python 3.9 jobs (since those are the only ones kicked off on PRs) and confirmed that these jobs were not passed down to thebuildjob. Is that good enough? No probably not, but what are you going to do about it?Final question - Was this a good use of my time?: Probably not. PyArrow will be out soon and we could've just had broken nightlies for Python 3.13 until then b/c no one is really using Python 3.13. But I know that my teammates will express great admiration and gratitude for making the little box green instead of red and that makes it alllllll worth it.
