Is Weights Manager supported? #1052

Closed alvoron closed 1 year ago

alvoron commented 1 year ago

Hello,

I've found Weights Manager feature described in https://arm-software.github.io/ComputeLibrary/v23.02.1/architecture.xhtml#architecture_weights_manager

I've found that Weights Manager is used in several functions (e.g. NEGEMM, NEFullyConnectedLayer) however, IWeightsManager::acquire and IWeightsManager::run methods are never called.

Tests against IWeightsManager class are also missed. Is this feature workable? Is there any example/test how to use it?

Thank you.

Hi @alvoron

The Weights Manager is only used in Fully Connecter Layer and is going to be deprecated soon as it is no longer actively maintained.

IWeightsManager is the interface of an internal ACL component that let us reuse already transformed weights in multiple functions at runtime and in this way avoid having to reshape the weights many times. This improves the performance and reduces the memory usage.

If you are looking way to improve memory consumption in general I would suggest you look into TensorAllocator::import_memory(), see import_memory

You can also see how to import memory in our validation tests for import_memory here

We are going to improve the documentation for importing memory in the release 24.02

Hope this helps.
