Struct TrainingHistory 

pub struct TrainingHistory {
    pub epoch_losses: Vec<f64>,
    pub epoch_times: Vec<f64>,
    pub batch_losses: Vec<f64>,
    pub stopped_early: bool,
}

Training history tracking loss over epochs and batches.

Fields

epoch_losses: Vec<f64>

Loss at the end of each epoch

epoch_times: Vec<f64>

Wall-clock time (seconds) for each epoch

batch_losses: Vec<f64>

Loss for each batch across all epochs

stopped_early: bool

True if training was stopped early due to validation loss plateau.

Trait Implementations

impl IntoPy<Py<PyAny>> for TrainingHistory

fn into_py(self, py: Python<'_>) -> PyObject

👎Deprecated since 0.23.0:

IntoPy is going to be replaced by IntoPyObject. See the migration guide (https://pyo3.rs/v0.23.0/migration) for more information.

Performs the conversion.

impl Clone for TrainingHistory

fn clone(&self) -> TrainingHistory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'py> IntoPyObject<'py> for TrainingHistory

type Target = TrainingHistory

The Python output type

type Output = Bound<'py, <TrainingHistory as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PyClass for TrainingHistory

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for TrainingHistory

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<TrainingHistory>

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForTrainingHistory

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
