SetData

Function Usage

Sets the data at the specified position for a host tensor obtained through AllocHostTensor.

Prototype

• Sets the value at the specified index for a tensor.

  void SetData(int64_t index, const T value, op::DataType dataType)

• Initializes tensor data with an existing memory.

  void SetData(const T *value, uint64_t size, op::DataType dataType)

Parameters

For details about ge::DataType, see ge::DataType in Basic Data Structures and API Reference.

• API for setting the value at the specified index

  Parameter	Input/Output	Description
  index	Input	Sequence number of an aclTensor element to be modified.
  value	Input	Value to which a specified element of the aclTensor is changed.
  dataType	Input	The data type is op::DataType (that is, ge::DataType). It converts the value to a specified type and then writes the value to the aclTensor.

• API for initializing tensor data with an existing memory

  Parameter	Input/Output	Description
  value	Input	Data memory pointer to be written to the aclTensor.
  size	Input	Number of elements to be written.
  dataType	Input	The data type is op::DataType (that is, ge::DataType). The data is converted into a specified data type and then written to aclTensor.

Returns

None

Constraints

The input parameter pointer must not be null.

// Initialize an int64_t memory and set the first 10 digits of the input to the content of the memory. Set the 11th digit of the input to the first digit of myArray.
void Func(const aclTensor *input) {
    int64_t myArray[10];
    input->SetData(myArray, 10, DT_INT64);
    input->SetData(10, myArray[0], DT_INT64);
