import mlflow # Search for all runs in the experiment with the specified experiment_id, # sorted by RMSE in ascending order runs_df = mlflow.search_runs( experiment_ids=[experiment_id], order_by=["metrics.rmse ASC"], max_results=1 ) # Get the run_id of the run with the best (lowest) RMSE best_run_id = runs_df.iloc[0]['run_id'] print(f"The run_id with the best RMSE is: {best_run_id}")

Selected Answer: C

I think it should be C, since ordering by RMSE descending would give the run with *highest* RMSE, i.e. the worst run first.
