### Describe the bug more legacy nonsense. The functions geometric_mean_absolute_error and geometric_mean_squared_error contain untested code ``` output_errors = _weighted_geometric_mean( np.abs(errors), sample_weight=horizon_weight, axis=0, ) ``` but the actual signature of _weighted_geometric_mean...

### Describe the bug some legacy code in weighted_metrics allows None arguments for the weights, then tests weights.ndim, so crashes if you dont pass weights. I would KWF but its...
