Function Usage

Obtains the model description from the memory if variables need to be dynamically updated during model execution.

Prototype

      
           aclError aclmdlBundleQueryInfoFromMem(const void *model, size_t modelSize, aclmdlBundleQueryInfo *queryInfo)

Parameters

Parameter	Input/Output	Description
model	Input	Pointer to the memory address for storing model data. The model file is built using the graph build API. Call aclgrphBundleBuildModel to compile the model, call aclgrphBundleSaveModel to save the model, and then load the saved .om model file into the memory. For details about the graph APIs, see aclgrphBundleBuildModel in Graph Development. In Ascend EP form, allocate memory on the host. In Ascend RC form, allocate memory on the device. In Ctrl CPU open form, allocate memory on the device.
modelSize	Input	Size of the model data in the memory, in bytes.
queryInfo	Output	Data of the aclmdlBundleQueryInfo type created by calling aclmdlBundleCreateQueryInfo.
