While computing multiclass `precision()`, some levels had no predicted events
(i.e. `true_positive + false_positive = 0`).
Precision is undefined in this case, and those levels will be removed from the
averaged result.
Note that the following number of true events actually occurred for each
problematic event level:
'2': 4, While computing multiclass `precision()`, some levels had no predicted events
