Description

Executes a specified operator. This API is asynchronous.

The inputs, outputs, and attributes of operators are different from each other. This API searches for the corresponding task based on the optype, input tensor description, output tensor description, and attributes, and delivers the task for execution. Organize operators in strict accordance with their inputs, outputs, and attributes when calling this API.

Prototype

aclError aclopExecute(const char *opType,
int numInputs,
const aclTensorDesc *const inputDesc[],
const aclDataBuffer *const inputs[],
int numOutputs,
const aclTensorDesc *const outputDesc[],
aclDataBuffer *const outputs[],
const aclopAttr *attr,
aclrtStream stream)

Parameters

Parameter	Input/Output	Description
opType	Input	Pointer to the operator type name.
numInputs	Input	Number of input tensors.
inputDesc	Input	Pointer array of the input tensor description. Call aclCreateTensorDesc to create data of the aclTensorDesc type in advance. The array length is consistent with numInputs. The elements in the inputs array match those in the inputDesc array.
inputs	Input	Pointer array of the input tensors. Call aclCreateDataBuffer to create data of the aclDataBuffer type in advance. The array length is consistent with numInputs. The elements in the inputs array match those in the inputDesc array.
numOutputs	Input	Number of output tensors. The array length is consistent with numOutputs.
outputDesc	Input	Pointer array of the output tensor description. Call aclCreateTensorDesc to create data of the aclTensorDesc type in advance. The array length is consistent with numOutputs. The elements in the outputs array match those in the outputDesc array.
outputs	Output	Pointer array of the output tensors. Call aclCreateDataBuffer to create data of the aclDataBuffer type in advance. The array length is consistent with numOutputs. The elements in the outputs array match those in the outputDesc array with ordering preserved.
attr	Input	Pointer to the operator attributes. Call aclopCreateAttr to create data of the aclopAttr type in advance.
stream	Input	Target stream of the operator.

Returns

0 on success; else, failure. For details, see aclError.

Restrictions

In multi-thread scenarios, you cannot specify the same stream or use the default stream when calling this API. Otherwise, the task execution may be abnormal.
