@hippocookie Thanks for taking this on, it seems like there might still be a couple more ufmt failures https://hud.pytorch.org/pr/pytorch/pytorch/126663#25386453576, could you fix these please?

[hippocookie]

Due to inconsistent of my black version, there's some wrong format not found on my machine, I think this time it might be work, thanks for you help! :D @mikaylagawarecki
