Description
The ML service has some coupling with ONNX Runtime: much of the logic in the base inference class is only relevant to this backend, while handling for other backends is treated as a special case. This PR abstracts ONNX Runtime into a
ModelSession
wrapper similar to how ARM NN is handled.The catalyst for this change is that facial recognition recently broke for ARM NN due to a change that only applied to ONNX Runtime. As part of this, it also adds relevant tests for facial recognition, as well as
AnnSession
in general as its test coverage was quite low.How Has This Been Tested?
Tested that the endpoint still works for each model task using ONNX Runtime. I'm unable to test ARM NN.
