Face Recognition Example is failing with WebNN built

[maheshpalkar]

Hi,

1. Built chromium for Webnn support.
2. Installed openvino 2020.2.120.

System configuration : Operating system: Linux (Ubuntu 18.04) Processor Generation: 8 Openvino Version: 2020.2.120

Issue : I have executed built with out/Default/chrome --no-sandbox --use-inference-engine Tried Face Recognition Example shows Prediction Failed with an error create execution fails. I have attached a screenshot of the issue.

Expected Result : Face Recognition Example having FaceNet and Face Reidentification mode should work with openvino as an inference engine WebNN support.

Hi, @maheshpalkar , SUSTAINED_SPEED backend on inference engine requires Intel Graphics, if not Intel Graphics, the examples will fail with the error createExecution fails:5 and you can see the logs like:

Terminal log: [IE] exception failed to create engine: clGetPlatformIDs error

Besides, Face Recognition isn't supported on inference engine backends currently because broadcasting isn't supported, please see the wiki WebML-Examples-Results-on-Different-Backends-and-Platforms.

Hi @Christywl, I am having intel graphics installed in my ubuntu machine. I am using a NUC machine. I have attached the system configuration screenshot. Still I am getting the same error "createExecution fails:5" for SUSTAINED_SPEED backend.

But when I select FAST_SINGLE_ANSWER then it shows "finishfails" and in terminal it shows broadcasting isn't supported.

Could you please post the logs in your terminal for SUSTAINED_SPEED backend?

Hi @Christywl,

Please find the attached screenshot of the terminal logs.

The build contains an old inference engine which doesn't support this device. We're upgrading inference engine now, please try it again after https://github.com/otcshare/chromium-src/pull/27 is merged. Thanks for trying WebNN.

Hi @Christywl, Thank you for providing the link of updated chromium source code. Is there a solution for the broadcasting issue?

According to IE doc, Add and Multiply support broadcasting. We may need to revisit #751 and #725.
