pip install amd_aiter-0.1.12+20260421-cp312-cp312-linux_x86_64.whl

Or one-shot:

pip install --force-reinstall https://rocm.frameworks-nightlies.amd.com/whl-staging/gfx942-gfx950/amd_aiter-0.1.12%2B20260421-cp312-cp312-linux_x86_64.whl

Smoke-test asks

• vLLM ml-ci-internal rebuild against this wheel (validates Building 0.1.12.post1 with PREBUILD_KERNELS fails #2837 fix end-to-end)
• python -c "import aiter" + a quick op_test pass on MI325 / MI355X
• Any blocking issues, please report on this issue or on PR [release/v0.1.12] Cherry-pick #2839: add missing c10/hip/HIPException.h include #2842

Caveats

• Version is 0.1.12+20260421 — date-stamped local segment, no +rocm7.2.2 suffix. PEP 440 ordering: 0.1.12+20260421 < 0.1.12.post1, so it will not accidentally displace post1 in resolvers. The official v0.1.12.post2 build will carry the proper +rocm7.2.2 suffix.
• Trial wheel only — not yet validated through downstream CI on PR [release/v0.1.12] Cherry-pick #2839: add missing c10/hip/HIPException.h include #2842.
