Enum TrainError 

pub enum TrainError {
    Config(ConfigError),
    Dataset(DatasetError),
    Mae(MaeError),
    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.

Mae(MaeError)

A MAE pretraining patchify / masking error (ADR-152 §2.3).

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

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

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.
