[Auto] pass kwargs to fixed_cross_entropy (cluster-43240-3): merged 1 of 2 PRs

[evalstate]

Cluster: cluster-43240-3

Merged:

• Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251 - Merged cleanly and implements the kwargs forwarding fix with stronger review signal and approvals.

Skipped:

• Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 - Alternative implementation of the same fix; after merging Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251 it conflicted in the same hunk with only stylistic differences, so it was redundant.

Failed:

• None.

Notes:

• Cluster contains issue kwargs are not passed to loss calculation function. huggingface/transformers#43240 and PRs Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251 and Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254.
• Issue kwargs are not passed to loss calculation function. huggingface/transformers#43240 is closed, but appears stale-closed rather than fixed; base code still did not forward weight and label_smoothing into nn.functional.cross_entropy.
• Both PRs merged cleanly when tested individually against origin/main.
• After merging Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251, attempting Add supported kwargs to fixed_cross_entropy huggingface/transformers#43254 produced a content conflict in src/transformers/loss/loss_utils.py because both PRs modify the same logic.
• Validated the merged file with: python -m py_compile src/transformers/loss/loss_utils.py
• Local merge commit: 00a8bc8

Next steps:

• Review the local merge of Fix(43240): pass kwargs to nn.functional.cross_entropy huggingface/transformers#43251.
• If desired, run targeted tests around loss_utils once a torch-enabled environment is available.
• Ignore or clean up untracked local agent artifacts before further handoff.
