Fix WHEEL Tag mismatch in transformer-engine-cu12 wheels

[eyupcanakman]

Description

The transformer-engine-cu12 wheels on PyPI have a mismatch. The filename tag is py3-none-manylinux_2_28_x86_64. The internal WHEEL metadata Tag: is cp310-cp310-manylinux_2_28_x86_64, so tools that read the metadata treat the wheel as Python-3.10-only.

bdist_wheel is invoked with --python-tag=py3 which sets the filename, but the WHEEL Tag still reflects the build python (cp310). The fix sets the Tag to py3-none right before wheel pack, next to the existing Name: rewrites for the cu12 suffix.

Verified locally by replaying the sed steps against the published 2.13.0 x86_64 and aarch64 wheels; the repacked artifact's filename and internal Tag both become py3-none-manylinux_2_28_<arch>. No CI exercises build_wheels.sh.

Fixes #2896

Type of change

• Documentation change (change only to the documentation, either a fix or a new content)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Infra/Build change
• Code refactoring

Changes

• Add a sed in build_tools/wheel_utils/build_wheels.sh that rewrites Tag: cp310-cp310 to Tag: py3-none in the WHEEL metadata before wheel pack. The literal cp310-cp310 matches the existing convention in this script (cp310 is hardcoded for the build interpreter in 7+ places).

Greptile Summary

This PR fixes a Tag: field mismatch in the WHEEL metadata for transformer-engine-cu12 wheels, where the filename correctly reflected py3-none (set via --python-tag=py3) but the internal metadata still recorded cp310-cp310 (from the build interpreter). The one-line sed is inserted at the right point in the script — after the dist-info directory is renamed and before wheel pack — so the repacked artifact's internal tag and filename are consistent.

Confidence Score: 5/5

Safe to merge — minimal, targeted fix with no functional regressions and consistent with existing cp310 hardcoding conventions in the script.

The change is a single sed substitution operating on the correct file path (post-rename dist-info), the replacement string py3-none is the right tag for a generic Python 3 platform wheel, the -g flag safely handles any duplicate Tag lines, and the rest of the rename pipeline (whl_name_target construction from dist/ baseline) remains unaffected. No P0 or P1 issues found.

No files require special attention.
