UpdateGraphRefreshableFeatureMemoryBase

Applicability

Header File/Library File

• Header file: #include <ge/ge_api_v2.h>
• Library file: libge_runner_v2.so

Function Usage

Updates the base address of the feature memory that can be updated except fixed memory.

Before calling this API, call CompileGraph to build the graph. The memory size is obtained from GetCompiledGraphSummary > GetRefreshableFeatureMemorySize.

If the graph has fixed memory and SetGraphFixedFeatureMemoryBaseWithType is not called to set the base address of the fixed feature memory for the default memory type, the fixed memory is automatically allocated by default.

Feature memory refers to the intermediate memory required during model execution (for example, the input and output memories of intermediate nodes).

Parameters

Returns

Constraints

• After compiling a graph by calling CompileGraph, you can call GetCompiledGraphSummary to check whether the feature address can be updated. Only graphs whose feature addresses can be updated can call this API again to update the feature addresses.
• This API applies only to statically compiled graphs. You can call the IsStatic API of GetCompiledGraphSummary to check whether a graph is statically compiled.
• If this API is used and RegisterExternalAllocator is configured, RegisterExternalAllocator does not take effect.
• If the address of the fixed memory with the memory type MEMORY_TYPE_DEFAULT is set to a nullptr and size is set to 0 through SetGraphConstMemoryBase or SetGraphFixedFeatureMemoryBaseWithType, the fixed memory function is disabled. In this case, this API cannot be called.
• This API cannot be called along with UpdateGraphFeatureMemoryBase.
