Enum tfrecord::protobuf::VariableAggregation

#[repr(i32)]
pub enum VariableAggregation {
    None,
    Sum,
    Mean,
    OnlyFirstReplica,
}

Indicates how a distributed variable will be aggregated.

Variants

None

NONE: This is the default, giving an error if you use a variable-update operation with multiple replicas.

Sum

SUM: Add the updates across replicas.

Mean

MEAN: Take the arithmetic mean (“average”) of the updates across replicas.

OnlyFirstReplica

ONLY_FIRST_REPLICA: This is for when every replica is performing the same update, but we only want to perform the update once. Used, e.g., for the global step counter.

Implementations

impl VariableAggregation

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of VariableAggregation.

pub fn from_i32(value: i32) -> Option<VariableAggregation>

Converts an i32 to a VariableAggregation, or None if value is not a valid variant.

Trait Implementations

impl Clone for VariableAggregation

impl Default for VariableAggregation

fn default() -> VariableAggregation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VariableAggregation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
