Reverted https://github.com/pytorch/pytorch/pull/89777 on behalf of https://github.com/clee2000 due to breaking test_ao_sparcity due to import https://hud.pytorch.org/pytorch/pytorch/commit/3531e44307fa58460e2488bcaace948678d6cf9f https://github.com/pytorch/pytorch/actions/runs/3641476330/jobs/6147830487, probably a landrace with 824641b083860df4d7ffef06a798ea2702bc4bde?
