Daniele Nerini focused on improving dependency management and error handling in the ecmwf/anemoi-utils repository during July 2025. He refactored the integration of MLflow, making it an optional dependency through conditional imports in Python, which allows the core functionality to operate even when MLflow is not installed. To enhance user experience, he implemented explicit error messaging that informs users when MLflow is missing. Additionally, Daniele updated the packaging to include the requests library as part of the MLflow optional dependencies, ensuring compatibility with new submodules. His work maintained backward compatibility and minimized the impact on the existing codebase.
