aclopLoad

Applicability

Description

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

Returns

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

Restrictions

• In the dynamic-shape operator scenario and Ascend virtual instance scenario, the operator library version in the model file loading environment must be the same as that in the model build environment. Otherwise, an error is reported when the operator is loaded.

  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 app will be abnormal.
