Edge AI Certification--NOOB Question

[Benjamin_Thompson]

So, I'm taking the tests for each Edge AI Certification section and I've hit one that I can't decipher. It's in the test for lesson 5: Model Optimizer. 

Here are screenshots of the question and the response I get regardless of which items I select for an answer. 

Removed unused layers doesn't work.

Permutations with it don't work.

FP 16 and GPU don't work (as the incorrect response sort of suggests (if ONNX runs on the same hardware, it therefore supports FP16 and infers on GPUs, right?)

So--what's the right answer?

Thanks!

It's a combination of three: "remove unused layers", plus "FP16 version" plus "non-default input and output".

Thanks! But not to run on a GPU (which requires FP16)?

No, converting an ONNX model to IR format is not required to perform inference on the GPU - the ONNX runtime supports the same hardware as OpenVINO; the ONNX model can directly be used without a prior conversion to IR format.
