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 = tf.keras.metrics.get("categorical_crossentropy")
type(metric)
<class 'function'>
metric = tf.keras.metrics.get("CategoricalCrossentropy")
type(metric)
<class '...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 = tf.keras.metrics.get(identifier)
type(metric)
<class '...metrics.CategoricalCrossentropy'>
