This violates PEP 8 naming conventions (local variables should be lowercase) and can lead to confusion or potential `UnboundLocalError` if `ModelManager` is referenced elsewhere in the function. It is better to use a lowercase variable name like `model_manager_cls`. ```suggestion model_manager_cls = _try_import_model_manager(throw_error=True) logging.info("Using Model Manager to manage models automatically.") model_manager = multi_process_shared.MultiProcessShared( lambda: model_manager_cls(**self._model_manager_args), ``` <details> <summary>References</summary> 1. PEP 8 states that variable names should be lowercase, with words separated by underscores as necessary. Shadowing global names with local variables of the same name should also be avoided. <sup>([link](https://github.com/apache/beam/blob/master/.gemini/styleguide.md))</sup> </details> -- This is an automated message from the Apache Git Service.
