tff.learning.federated_aggregate_keras_metric

Aggregates variables a keras metric placed at CLIENTS to SERVER.

tff.learning.federated_aggregate_keras_metric(
    metrics: Union[tf.keras.metrics.Metric, Sequence[tf.keras.metrics.Metric], Callable[
        [], tf.keras.metrics.Metric], Sequence[Callable[[], tf.keras.metrics.
        Metric]]],
    federated_values
)

Args
`metrics`	A single or a `Sequence` of `tf.keras.metrics.Metric` objects, or a single or a `Sequence` of no-arg callables that each constructs a `tf.keras.metrics.Metric`. The order must match the order of variables in `federated_values`.
`federated_values`	A single federated value, or a `Sequence` of federated values. The values must all have `tff.CLIENTS` placement. If value is a `Sequence` type, it must match the order of the sequence in `metrics.

Returns
The result of performing a federated sum on federated_values, then assigning the aggregated values into the variables of the corresponding `tf.keras.metrics.Metric` and calling `tf.keras.metrics.Metric.result`. The resulting structure has `tff.SERVER` placement.
