Detailed Documentation

Computes indices and values of the k maximum/minimum values for each slice along specified axis.

Construction

TopK()

Constructs a TopK operation.

TopK(
    const Output<Node>& data,
    const Output<Node>& k,
    const int64_t axis,
    const std::string& mode,
    const std::string& sort,
    const element::Type& index_element_type = element::i32
    )

Constructs a TopK operation with two outputs: values and indices. By default the indices output is described by i32 data type.

Parameters:

data

The input tensor

k

Specifies how many maximum/minimum elements should be computed (note: scalar input tensor)

axis

The axis along which to compute top k indices

mode

Specifies which operation (min or max) is used to select the biggest element of two.

sort

Specifies order of output elements and/or indices Accepted values: none, index, value

index_element_type

Specyfies type of produced indices

Methods

virtual void validate_and_infer_types()

Verifies that attributes and inputs are consistent and computes output shapes and element types. Must be implemented by concrete child classes so that it can be run any number of times.

Throws if the node is invalid.

uint64_t get_axis() const

Returns axis value after normalization.

If input rank required to normalization is dynamic, the exception is thrown

int64_t get_provided_axis() const

Returns axis value before normalization.

size_t get_k() const

Returns the value of K, if available.

If the second input to this op is a constant, the value is retrieved and returned. If the input is not constant(dynamic) this method returns 0

virtual size_t get_default_output_index() const

Returns the output of the default output, or throws if there is none.

virtual OPENVINO_SUPPRESS_DEPRECATED_START bool evaluate(
    const HostTensorVector& output_values,
    const HostTensorVector& input_values
    ) const

Evaluates the op on input_values putting results in output_values.

Deprecated Use evaluate with ov::Tensor instead

Parameters:

output_values

Tensors for the outputs to compute. One for each result

input_values

Tensors for the inputs. One for each inputs.

Returns:

true if successful

virtual OPENVINO_SUPPRESS_DEPRECATED_END bool has_evaluate() const

Allows to get information about availability of evaluate method for the current operation.
