Enums

enum QnnSystemTensor_Error_t

QNN System Tensor API result / error codes.

Values:

enumerator QNN_SYSTEM_TENSOR_MIN_ERROR = 30000
enumerator QNN_SYSTEM_TENSOR_NO_ERROR = QNN_SYSTEM_COMMON_NO_ERROR

Qnn System Tensor success.

enumerator QNN_SYSTEM_TENSOR_ERROR_UNSUPPORTED_FEATURE = QNN_COMMON_ERROR_NOT_SUPPORTED

Qnn System Tensor API is not supported yet.

enumerator QNN_SYSTEM_TENSOR_ERROR_INVALID_ARGUMENT = QNN_SYSTEM_COMMON_ERROR_INVALID_ARGUMENT

One or more arguments to a System Tensor API is/are NULL/invalid.

enumerator QNN_SYSTEM_TENSOR_ERROR_INVALID_TENSOR = QNN_SYSTEM_TENSOR_MIN_ERROR + 2

A Qnn_Tensor_t data structure in invalid.

enumerator QNN_SYSTEM_TENSOR_MAX_ERROR = 49999

Functions

Qnn_ErrorHandle_t QnnSystemTensor_getMemoryFootprint(Qnn_Tensor_t tensor, uint64_t *footprint)

A function to compute the maximum amount of memory in bytes required to contain tensor data. Currently supported data formats are:

  • QNN_DATA_FORMAT_DENSE

Parameters

  • tensor – [in] A Qnn_Tensor_t data structure.

  • footprint – [out] The maximum amount of memory required to fully contain tensor data.

Returns

Error code

  • QNN_SUCCESS: Successfully compute the tensor memory extent

  • QNN_SYSTEM_TENSOR_ERROR_INVALID_ARGUMENT: extent is NULL

  • QNN_SYSTEM_TENSOR_ERROR_INVALID_TENSOR: tensor is ill-configured

  • QNN_SYSTEM_TENSOR_ERROR_UNSUPPORTED_FEATURE: this API is not supported yet
