Thanks! There's something wrong with the wheel build; seems unrelated but if you have time to look into it, hopefully not too bad to fix.

Looks like that did work to fix the diff_shades, but now the mypyc wheel build is failing. I think it might be spurious, or at least not my fualt, since the error is Cannot download, all mirrors were already tried without success from sh -c 'yum install -y clang gcc', and I don't see why updating the upload-artifact version would affect it.

I tried looking at a previous run to see if it reports what url succeeded, but no dice. When I try to go to some of those URLs myself I also get 404s, so no clue what's happening, and extra not sure what to do since I'm on windows and very unfamiliar with anything linux.

@JelleZijlstra can you retry the mypyc build? I manually checked all the links it lists for the mirrors, and two of them work for downloading the file, so I think it might succeed if it re-runs. The two working links:

• http://mirror.facebook.net/almalinux/8.10/AppStream/x86_64/os/repodata/31d0e735277fdcbc5e8cbb57177a827c3e9aa139e97a603980f6317165fdb4c9-modules.yaml.gz

Thanks, retried!

@JelleZijlstra it succeeded, so looks like it was just that one still working endpoint having a networking hiccup. I think this should be good for merge now that that's resolved.
