Methods

impl Downsample

pub fn new(axis: usize, stride: usize, modulo: usize) -> Self

Constructs a new Downsample.

Trait Implementations

impl InferenceRulesOp for Downsample

fn rules<'r, 'p: 'r, 's: 'r>(
    &'s self,
    s: &mut Solver<'r>,
    inputs: &'p [TensorProxy],
    outputs: &'p [TensorProxy]
) -> InferenceResult

Registers the inference rules of the operator.

fn as_op(&self) -> &dyn Op

fn as_op_mut(&mut self) -> &mut dyn Op

fn to_typed(
    &self,
    _source: &InferenceModel,
    node: &InferenceNode,
    target: &mut TypedModel,
    mapping: &HashMap<OutletId, OutletId>
) -> TractResult<TVec<OutletId>>

fn nboutputs(&self) -> TractResult<usize>

impl StatelessOp for Downsample

fn eval(&self, inputs: TVec<Arc<Tensor>>) -> TractResult<TVec<Arc<Tensor>>>

impl Op for Downsample

fn name(&self) -> Cow<str>

fn info(&self) -> TractResult<Vec<String>>

Short (one-line) strings giving hints on internal implementation or important configuration details to be displayed in dumps.

fn declutter(
    &self,
    model: &TypedModel,
    node: &TypedNode
) -> TractResult<Option<TypedModelPatch>>

Declutter the op to the tract_core operator set as much as possible.

fn same_as(&self, other: &dyn Op) -> bool

Compare two ops.

fn as_typed(&self) -> Option<&dyn TypedOp>

fn incorporate(
    &self,
    _model: &InferenceModel,
    _node: &InferenceNode
) -> TractResult<Option<InferenceModelPatch>>

Early pass on inference model, after analyse, but before translation to typed network. Meant to deal with some framework idiosyncrasies that manifest with temporaries nodes that can run some form of inference but require refactoring the network before it can be evaluated.

fn codegen(
    &self,
    _model: &TypedModel,
    _node: &TypedNode
) -> TractResult<Option<TypedModelPatch>>

Translate the op into the most efficient form possible for execution.

fn fuse(
    &self,
    _model: &TypedModel,
    _node: &TypedNode
) -> TractResult<Option<TypedModelPatch>>

Fuse op after codegen to deal with local optimisations.

fn cost(&self, _inputs: &[&TypedTensorInfo]) -> TractResult<TVec<(Cost, TDim)>>

Computes a cost hint of the operation.

fn nested_models(&self) -> Vec<(Cow<str>, &dyn Model)>

Nested models, with label (for audit).

fn validation(&self) -> Validation

The kind of accuracy check that should be performed on operation when testing them.

fn axes_info(
    &self,
    _model: &TypedModel,
    _node: &TypedNode
) -> TractResult<AxesInfo>

fn is_canonic(&self) -> bool

impl TypedOp for Downsample

fn as_op(&self) -> &dyn Op

Reinterpret the TypedOp as an Op.

fn as_op_mut(&mut self) -> &mut dyn Op

Reinterpret the TypedOp as an Op, mutably.

fn output_facts(
    &self,
    inputs: &[&TypedTensorInfo]
) -> TractResult<TVec<TypedTensorInfo>>

Deduce output facts from input facts.

fn pulsify(
    &self,
    _source: &NormalizedModel,
    node: &NormalizedNode,
    target: &mut PulsedModel,
    mapping: &HashMap<OutletId, OutletId>,
    _pulse: usize
) -> TractResult<TVec<OutletId>>

Translate an op in a normalized network (no constants) to a pulsing form, if possible.

fn dispose_dummy_axis(
    &self,
    model: &TypedModel,
    node: &TypedNode,
    axis: usize
) -> TractResult<Option<Box<dyn TypedOp>>>

Transforms the op in an equivalent one, discarding one dummy axis (of dim assumed to be 1).

fn nested_model_multipliers(
    &self,
    inputs: &[&TypedTensorInfo]
) -> Vec<(Cow<str>, f32)>

Nested model multipliers, with label (for profiling).

impl Default for Downsample

fn default() -> Downsample

Returns the "default value" for a type.

impl Clone for Downsample

fn clone(&self) -> Downsample

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Downsample> for Downsample

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Downsample

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

Formats the value using the given formatter.
