Retrieves a Keras metric as a function
/Metric
class instance.
tf.keras.metrics.get(
identifier
)
The identifier
may be the string name of a metric function or class.
metric = metrics.get("categorical_crossentropy")
type(metric)
<class x27;function'>
metric = metrics.get("CategoricalCrossentropy")
type(metric)
<class x27;...metrics.CategoricalCrossentropy'>
You can also specify config
of the metric to this function by passing dict
containing class_name
and config
as an identifier. Also note that the
class_name
must map to a Metric
class
identifier = {"class_name": "CategoricalCrossentropy",
"config": {"from_logits": True} }
metric = metrics.get(identifier)
type(metric)
<class x27;...metrics.CategoricalCrossentropy'>
