class AbstractTensor : public mindspore::abstract::AbstractUndetermined

Class AbstractTensor describes a tensor’s type, shape and value.

Subclassed by mindspore::abstract::AbstractRef

Public Functions

inline explicit AbstractTensor(const AbstractBasePtr &element, const BaseShapePtr &shape = std::make_shared<Shape>())

Constructor of AbstractTensor.

Parameters

  • element – [in] The abstract to be wrapper as a abstract tensor.

  • shape – [in] The dimension of abstract tensor.

inline AbstractTensor(const TypePtr &element_type, const ShapeVector &shape)

Constructor of AbstractScalar.

Parameters

  • element_type – [in] The type of abstract tensor.

  • shape – [in] A vector of the tensor’s shape.

inline explicit AbstractTensor(const tensor::TensorPtr &tensor)

Constructor of AbstractScalar.

Parameters

tensor – [in] The tensor to be abstracted.

inline explicit AbstractTensor(const TypePtr &element_type, const BaseShapePtr &shape = std::make_shared<Shape>())

Constructor of AbstractScalar.

Parameters

  • element_type – [in] The type of a tensor.

  • shape – [in] The dimension of a tensor.

~AbstractTensor() override = default

Destructor of AbstractTensor.

MS_DECLARE_PARENT (AbstractTensor, AbstractUndetermined) void set_value_range(const ValuePtr &min_value

Set min value and max value.

Parameters

  • min_value – [in] The min value of tensor.

  • max_value – [in] The max value of tensor.

inline const ValuePtr &get_min_value() const

Get the min value.

Returns

A pointer to a value.

inline const ValuePtr &get_max_value() const

Get the max value.

Returns

A pointer to a value.

virtual TypePtr BuildType() const override

Build the type of the abstract.

Note

Use this function to get the actual type, while track type is not enough accurate.

Returns

A pointer to the Type.

virtual BaseShapePtr BuildShape() const override

Build the shape of the abstract.

Note

Use this function to get the actual shape, while track shape is not enough accurate.

Returns

A pointer to the BaseShape.

virtual AbstractBasePtr Clone() const override

Clone an abstract from the abstract.

Returns

A pointer to the cloned abstract.

virtual AbstractBasePtr Broaden() const override

Broaden the abstract. It will upgrade the abstract to a higher level.

Returns

A pointer to the broadened abstract.

AbstractBasePtr BroadenWithShape() const

Broaden the abstract. It will upgrade the abstract to a higher level.

Note

The shape will be remained.

Returns

A pointer to the broadened abstract.

virtual AbstractBasePtr Join(const AbstractBasePtr &other) override

Combine two abstracts. If two abstracts are different, it will broaden the abstract value.

Parameters

other – [in] The other abstract to be joined.

Returns

A pointer to the combined abstract.

virtual std::string ToString() const override

Get the string representation of this object.

Returns

The string representation.

inline virtual std::size_t hash() const override

Get the hash value of this object.

Returns

The hash value.

virtual AbstractBasePtr PartialBroaden() const override

Broaden abstract with constraints.

Returns

A pointer to the broadened abstract.
