pub fn output_shape<D: DimLike>(
    &self,
    ishape: &[D],
    kshape: &[usize]
) -> TVec<D>

pub fn to_unary(
    &self,
    inputs: &[impl Borrow<TypedFact>]
) -> TractResult<Option<ConvUnary>>

    &self,

) -> TractResult<()>

Trait Implementations

impl InferenceRulesOp for Conv

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 Conv

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

impl Op for Conv

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

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

fn as_pulsed(&self) -> Option<&dyn PulsedOp>

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

Fuse op after codegen to deal with local optimisations.

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

Compare two ops.

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 is_canonic(&self) -> bool

impl TypedOp for Conv

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

Deduce output facts from input facts.

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

Computes a cost hint of the operation.

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

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

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

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

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

    &self,
    inputs: &[&TypedFact]

Nested model multipliers, with label (for profiling).
