OH_NN_Tensor

Overview

Defies the the tensor structure.

It is usually used to construct data nodes and operator parameters in a model diagram. When constructing a tensor, you need to specify the data type, number of dimensions, dimension information, and quantization information.

Since: 9

Deprecated: This module is deprecated since API version 11.

Substitute: You are advised to use NN_TensorDesc.

Summary

Member Variables

Name	Description
OH_NN_DataType dataType	Data type of the specified tensor. The value must be of the OH_NN_DataType type.
uint32_t dimensionCount	Number of dimensions of the specified tensor.
const int32_t * dimensions	Dimension information (shape) of the specified tensor.
const OH_NN_QuantParam * quantParam	Quantization information of the specified tensor. The data type must be OH_NN_QuantParam.
OH_NN_TensorType type	Type of the specified tensor. The value is related to the tensor usage. If the tensor is used as the input or output of the model, set type to OH_NN_TENSOR. If the tensor is used as an operator parameter, select an enum value other than OH_NN_TENSOR from OH_NN_TensorType.

type

OH_NN_TensorType OH_NN_Tensor::type

Description

Type of the specified tensor. The value is related to the tensor usage. If the tensor is used as the input or output of the model, set type to OH_NN_TENSOR. If the tensor is used as an operator parameter, select an enum value other than OH_NN_TENSOR from OH_NN_TensorType.
