fn clone(&self) -> Shape

Returns a copy of the value.

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

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

Compare two ops.

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

impl StatelessOp for Shape

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

Evaluates the operation given the input tensors.

impl TypedOp for Shape

fn fuse(
    &self,
    _model: &TypedModel,

Fuse op after codegen to deal with local optimisations.

fn declutter(
    &self,
    model: &TypedModel,
    node: &TypedNode
