Walkthrough

The updates include a configuration change in the code coverage settings to mark the project coverage status as informational, a modification in a utility function to restrict specific log messages to the main process only during dataset loading, and an extension of a function to support a new model type "llama4" by returning its corresponding attention class. No changes to public interfaces were made.

Changes

File(s)	Change Summary
codecov.yml	Added informational: true to coverage.status.project.default configuration.
src/axolotl/utils/data/shared.py	Changed two logging calls in load_preprocessed_dataset to use main_process_only=True.
src/axolotl/monkeypatch/lora_kernels.py	Extended get_attention_cls_from_config to handle "llama4" model type by returning Llama4TextAttention.

Poem

In the meadow of logs, where the data flows free,
Only the main bunny now shouts with glee.
Coverage reports whisper, "Just FYI,"
Informational flags wave as numbers fly.
A new llama friend joins the dance,
This rabbit’s updates enhance the chance! 🐇🦙

154-157: Confirmed “llama4” support and import path

The Hugging Face Transformers library (v4.51.0+) includes transformers.models.llama4.modeling_llama4, so the new branch in src/axolotl/monkeypatch/lora_kernels.py (lines 154–157) will import successfully. No further changes needed.

467-470: Align remaining LOG.info calls for consistency

Elsewhere in the same function (save_preprocessed_dataset at lines 431-435) the push-to-hub message is still broadcast to all processes (main_process_only=False).
If that wasn’t intentional, consider toggling it for symmetry:

-        LOG.info(
-            "Pushing merged prepared dataset to Huggingface hub at "
-            f"{cfg.push_dataset_to_hub} (version {dataset_hash})...",
-            main_process_only=False,
-        )
+        LOG.info(
+            "Pushing merged prepared dataset to Huggingface hub at "
+            f"{cfg.push_dataset_to_hub} (version {dataset_hash})...",
+            main_process_only=True,
+        )

25-25: Confirm Codecov “informational” flag path

The new informational: true key is helpful for preventing status-check failures on coverage drops.
Double-check that this nesting (coverage.status.project.default) matches the latest Codecov spec; otherwise the flag will be ignored.

461-465: Good move: suppress log spam on workers

Restricting this message to the main process reduces noise in multi-process runs. ✅
No issues spotted.
