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]],
    federated_values
)

Args
`metrics`	a single `tf.keras.metrics.Metric` or a `Sequence` of metrics . 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.
