AI Summary: The `mlflow.pyfunc.log_model` function's `artifact_path` argument is deprecated and should be replaced with `name` in the `pymc_marketing/mlflow.py` module. The task involves updating this argument and determining the appropriate strategy for MLflow version compatibility, either by handling both argument names or pinning the MLflow dependency.
