Function Usage

Loads the single-operator model data from the memory. The memory is managed by the user. The single-operator model data refers to the data that is loaded to the memory from the single-operator OM file.

Prototype

aclError aclopLoad(const void *model,  size_t modelSize)

Parameters

Parameter	Input/Output	Description
model	Input	Pointer to the memory address of the single-operator model data
modelSize	Input	Size of the model in the memory, in bytes

Returns

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

Restrictions

The operator package version in the model loading environment must match the version used in the model building environment. Otherwise, an error is reported during operator loading. You can check the operator library version by viewing the version field in the ${INSTALL_DIR}/opp/version.info file. Replace ${INSTALL_DIR} with the CANN component directory. For example, if the installation is performed by the root user, the default file storage path is /usr/local/Ascend/cann.

Before loading, check whether the memory space is sufficient based on the size of the single-operator OM file. If the memory space is insufficient, the application will be abnormal. The maximum number of operators being executed in a process varies depending on the product model.

For the Ascend 950PR/Ascend 950DT, Atlas A3 training products/Atlas A3 inference products, and Atlas A2 training products/Atlas A2 inference products, the limit is 2,000,000.
For the Atlas 200I/500 A2 inference products and Atlas training products, the limit is 40,000,000.
For the Atlas inference products, the limit is 40,000,000 in Ascend EP form and is 2,000,000 in Open Ctrl CPU form.
