tff.learning.framework.ClientOutput(
    weights_delta,
    weights_delta_weight,
    model_output,
    optimizer_output=attr_dict['optimizer_output'].default
)

weights_delta A dictionary of updates to the model's trainable variables.
weights_delta_weight Weight to use in a weighted mean when aggregating weights_delta.
model_output A structure matching tff.learning.Model.report_local_unfinalized_metrics, reflecting the results of training on the input dataset.
optimizer_output Additional metrics or other outputs defined by the optimizer.
