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]

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

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