class Tensor : public mindspore::api::Value

Tensor represents a multi-dimensional array of elements.

Public Functions

Tensor(TypeId data_type, const ShapeVector &shape)

Create a lazy allocated tensor.

Parameters

  • data_type – [in] [TypeId] Data type of the tensor.

  • shape – [in] The shape represented by ShapeVector of the tensor.

Tensor(TypeId data_type, const ShapeVector &shape, void *data, size_t data_len)

Create a tensor with input data buffer.

Parameters

  • data_type – [in] [TypeId] Data type of the tensor.

  • shape – [in] The shape represented by ShapeVector of the tensor.

  • data – [in] The input data to be copied into tensor.

  • data_len – [in] The length of data in bytes.

const ShapeVector &shape() const

Get the shape of the tensor. The shape of a tensor is stored in a vector<int64_t>. Each element of the vector represents the size of a dimension of the tensor. The order of each element in the vector is the same as the the dimension’s order it represents.

Returns

A vector<int64_t> which represents the shape of the tensor.

void set_shape(const ShapeVector &shape)

Set the shape of tensor.

Parameters

shape – [in] The shape to be set.

TypeId data_type() const

Get the data type of the tensor.

Returns

The data type of the tensor.

void set_data_type(const TypeId data_type)

Set the data type of the tensor.

Parameters

data_type – [in] The data type to be set.

const void *data() const

Get The pointer to the underlying memory block for data storage.

Returns

The pointer to the underlying data.

void *data()

Get The pointer to the underlying memory block for data storage.

Returns

The pointer to the underlying data.

size_t DataSize() const

Get tensor data size.

Returns

The total number of elements in the tensor.

std::size_t Size() const

Get tensor data size in bytes.

Returns

The total number of bytes for the tensor data.
