Enum TrainError 

pub enum TrainError {
    Config(ConfigError),
    Dataset(DatasetError),
    Json(Error),
    EmptyDataset,
    IndexOutOfBounds {
        index: usize,
        len: usize,
    },
    ShapeMismatch {
        expected: Vec<usize>,
        actual: Vec<usize>,
    },
    TrainingStep(String),
    Checkpoint {
        message: String,
        path: PathBuf,
    },
    NotImplemented(String),
}

Top-level error type for the WiFi-DensePose training pipeline.

Orchestration-level functions (e.g. [crate::trainer::Trainer] methods) return TrainResult<T>. Lower-level functions in crate::config and crate::dataset return their own module-specific error types which are automatically coerced into TrainError via From.

Variants

Config(ConfigError)

A configuration validation or loading error.

Dataset(DatasetError)

A dataset loading or access error.

Json(Error)

JSON (de)serialization error.

EmptyDataset

The dataset is empty and no training can be performed.

IndexOutOfBounds

Index out of bounds when accessing dataset items.

Fields

index: usize

The out-of-range index.

len: usize

The total number of items in the dataset.

ShapeMismatch

A shape mismatch was detected between two tensors.

Fields

expected: Vec<usize>

Expected shape.

actual: Vec<usize>

Actual shape.

TrainingStep(String)

A training step failed.

Checkpoint

A checkpoint could not be saved or loaded.

Fields

message: String

Human-readable description.

path: PathBuf

Path that was being accessed.

NotImplemented(String)

Feature not yet implemented.

Implementations

impl TrainError

pub fn training_step<S: Into<String>>(msg: S) -> Self

Construct a TrainError::TrainingStep.

pub fn checkpoint<S: Into<String>>(msg: S, path: impl Into<PathBuf>) -> Self

Construct a TrainError::Checkpoint.

pub fn not_implemented<S: Into<String>>(msg: S) -> Self

Construct a TrainError::NotImplemented.

pub fn shape_mismatch(expected: Vec<usize>, actual: Vec<usize>) -> Self

Construct a TrainError::ShapeMismatch.

Trait Implementations

impl Debug for TrainError

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

Formats the value using the given formatter.

impl Display for TrainError

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

Formats the value using the given formatter.

impl Error for TrainError

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 From<ConfigError> for TrainError

fn from(source: ConfigError) -> Self

Converts to this type from the input type.

impl From<DatasetError> for TrainError

fn from(source: DatasetError) -> Self

Converts to this type from the input type.

impl From<Error> for TrainError

fn from(source: Error) -> Self

Converts to this type from the input type.
