Constant¶
Constant // Literal constant tensor
Description¶
The output is a tensor initialized from the values attribute.
Attributes¶
| Name | Type | Notes |
|---|---|---|
type |
ngraph::element::type |
The element type of the value in the computation |
shape |
ngraph::Shape |
The shape of the constant |
values |
const std::vector<T>& |
Constant elements in row-major order. T must be compatible with the element type |
Outputs¶

C++ Interface¶
-
class
Constant: public ngraph::Node¶ Class for constants.
Subclassed by ngraph::op::ScalarConstantLikeBase
Public Functions
-
template <typename T>
Constant(const element::Type &type, Shape shape, const std::vector<T> &values)¶ Constructs a tensor constant.
- Parameters
type: The element type of the tensor constant.shape: The shape of the tensor constant.values: A vector of literals for initializing the tensor constant. The size of values must match the size of the shape.
-
Constant(const element::Type &type, Shape shape, const std::vector<std::string> &values)¶ Constructs a tensor constant This constructor is mainly to support deserialization of constants.
- Parameters
type: The element type of the tensor constant.shape: The shape of the tensor constant.values: A list of string values to use as the constant data.
-
Constant(const element::Type &type, const Shape &shape, const void *data)¶ Constructs a tensor constant with the same initialization value copied across.
- Parameters
type: The element type of the tensor constant.shape: The shape of the tensor constant.data: A void* to constant data.
-
void
validate_and_infer_types()¶ Throws if the node is invalid.
-
vector<string>
get_value_strings() const¶ - Return
- The initialization literals for the tensor constant.
Public Static Functions
-
template <typename T>
static std::shared_ptr<op::Constant>create(const element::Type &type, Shape shape, const std::vector<T> values)¶ Wrapper around constructing a shared_ptr of a Constant.
- Parameters
type: The element type of the tensor constant.shape: The shape of the tensor constant.values: A vector of values to use as the constant data.
-
template <typename T>
static std::shared_ptr<op::Constant>create(const element::Type &type, Shape shape, std::initializer_list<T> values)¶ Wrapper around constructing a shared_ptr of a Constant.
- Parameters
type: The element type of the tensor constant.shape: The shape of the tensor constant.values: An initializer_list of values to use as the constant data.
