[evalstate]

Cluster: cluster-43240-3
Base: origin/main

Merged PRs:

• Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251: Canonical cluster PR; clean local merge; forwards weight and label_smoothing through fixed_cross_entropy and had maintainer approvals.

Skipped PRs:

• Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254: Duplicative of merged PR Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251; conflicted on the same fixed_cross_entropy hunk after Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251 and provided no additional behavior.

Failed PRs:

• None

Notes:

• Issue kwargs are not passed to loss calculation function. huggingface/transformers#43240 is closed as stale/by bot, not by an already-merged fix, so the change still had merit.
• PR Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 applied cleanly by itself in a no-commit trial, but conflicted after merging PR Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251.
• Repository was left coherent on the requested branch with no unresolved merge.
• Untracked runtime/session artifacts were left untouched.

Validation:

• python -m py_compile src/transformers/loss/loss_utils.py passed.
• git diff --check origin/main...HEAD passed.
• Runtime smoke test could not run because torch is not installed in this environment.

Next steps:

• Run full style and relevant tests in an environment with project dependencies, especially torch.
• Consider closing or superseding PR Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 as duplicate of PR Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251.
