* fix(config): support policy.path in YAML config files policy.path was only handled via CLI args (filtered from sys.argv before draccus, then retrieved in validate()). When specified in YAML, draccus would crash because 'path' is not a valid field on PreTrainedConfig. Extract path fields from the YAML/JSON config before draccus processes it, store them in a module-level dict, and fall back to it in get_path_arg() when the CLI doesn't have the path. Fixes #2957 * fix(parser): preserve YAML policy overrides when loading from pretrained When policy.path is set in YAML, validate() was calling from_pretrained with only CLI overrides, discarding any YAML policy fields (e.g. lr, batch_size) that draccus had already parsed. Fix by capturing the remaining YAML fields as CLI-style args in _config_yaml_overrides and merging them into the overrides passed to from_pretrained in train.py, eval.py, and lerobot_record.py (CLI args still take precedence). Also fix the NamedTemporaryFile SIM115 ruff warning and add types-PyYAML to the mypy pre-commit hook. * fix(parser): serialize bool/None values correctly in YAML policy overrides Bool values from YAML configs (e.g. push_to_hub: true) were passed as Python "True"/"False" strings instead of lowercase "true"/"false" that draccus expects. Also skip None values to avoid passing "None" strings. * revert: remove types-PyYAML from .pre-commit-config.yaml * chore: fix quality check caused by untyped YAML import Co-authored-by: masato-ka <jp6uzv@gmail.com> Signed-off-by: Khalil Meftah <khalil.meftah@huggingface.co> --------- Signed-off-by: Khalil Meftah <khalil.meftah@huggingface.co> Co-authored-by: Khalil Meftah <khalil.meftah@huggingface.co> Co-authored-by: masato-ka <jp6uzv@gmail.com>
