Enum TrainingError 

pub enum TrainingError {
    EventProcessor(EventProcessorError),
    Dataset(DatasetError),
    Workers(Vec<WorkerFailure>),
    Checkpoint(CheckpointerError),
}

An error that stopped training or evaluation.

Variants

EventProcessor(EventProcessorError)

Error while processing events.

Dataset(DatasetError)

Error while loading data.

Workers(Vec<WorkerFailure>)

The training step panicked on one or more workers of a multi-device strategy.

Checkpoint(CheckpointerError)

Error while saving, restoring or deleting a checkpoint.

Implementations

impl TrainingError

pub fn is_device_poisoned(&self) -> bool

Whether the error comes from a poisoned device. In this case, every later operation will fail until the process is restarted.

Trait Implementations

impl Debug for TrainingError

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

Formats the value using the given formatter.

impl Display for TrainingError

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

Formats the value using the given formatter.

impl Error for TrainingError

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.
