#### model
A string value to indicate which model should be used. Use "short" to
select a short-range model that works best for faces within 2 meters from the
camera, and "full" for a full-range model best for faces within 5 meters. For
the full-range option, a sparse model is used for its improved inference speed.
Please refer to the model cards for details. Default to empty string.
