tf_agents.utils.tensor_normalizer.kahan_summation

Calculate stable acculated sum using compensation for low-bits.

tf_agents.utils.tensor_normalizer.kahan_summation(
    accumulator: tf_agents.typing.types.Float,
    carry: tf_agents.typing.types.Float,
    value: tf_agents.typing.types.Float
) -> Tuple[tf_agents.typing.types.Float, tf_agents.typing.types.Float]

accumulator Accumulator.
carry Carry for lost low-order bits.
value New value to accumlate.

A tuple (accumulator, carry) such that accumulator is the new accumulated value and carry is the new compensation value.
