Enum OptimizerDistError 

pub enum OptimizerDistError {
    WorkerNotFound(String),
    StaleUpdate {
        worker: String,
        step: u64,
        current: u64,
    },
    DimensionMismatch {
        layer: String,
        expected: usize,
        got: usize,
    },
}

Errors that can arise from DistributedOptimizer operations.

Variants

WorkerNotFound(String)

The worker is not registered with this optimizer.

StaleUpdate

The submitted update is too far behind the current global step.

Fields

worker: String

step: u64

current: u64

DimensionMismatch

The gradient dimensions do not match the expected layer width.

Fields

layer: String

expected: usize

got: usize

Trait Implementations

impl Clone for OptimizerDistError

fn clone(&self) -> OptimizerDistError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OptimizerDistError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for OptimizerDistError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for OptimizerDistError

impl Error for OptimizerDistError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for OptimizerDistError

fn eq(&self, other: &OptimizerDistError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
