Description

Runs model inference based on the attributes configured by the aclmdlSetExecConfigOpt API until the inference result is returned. This API is enhanced based on aclmdlExecuteAsync. It allows you to control configuration parameters during model inference. This API is asynchronous.

This API must be used together with other APIs to implement model execution. The API call sequence is as follows:

Call aclmdlCreateExecConfigHandle to create a configuration object for model execution.
Call aclmdlSetExecConfigOpt multiple times to set the value of each attribute in the configuration object.
Call aclmdlExecuteAsyncV2 to specify the configuration information required for model execution and execute the model.
After the model is successfully executed, call aclmdlDestroyExecConfigHandle to destroy the configuration object.

Prototype

aclError aclmdlExecuteAsyncV2(uint32_t modelId, const aclmdlDataset *input, aclmdlDataset *output, aclrtStream stream, const aclmdlExecConfigHandle *handle)

Parameters

Parameter	Input/Output	Description
modelId	Input	Model ID for inference. A successful aclmdlLoadFromFile, aclmdlLoadFromMem, aclmdlLoadFromFileWithMem, or aclmdlLoadFromMemWithMem call returns a model ID.
input	Input	Pointer to the input data for model inference.
output	Output	Pointer to the output data for model inference.
stream	Input	Stream.
handle	Input	Pointer to the configuration object executed by the model. The value must be the same as that of handle in aclmdlSetExecConfigOpt.

Returns

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

Restrictions

The restrictions are the same as those of aclmdlExecuteAsync.
