[2019R1] OpenVINO calibration tool: custom adapter

[Ermak__Aleksei]

Hi,

is it possible to create and use custom adapter for conversion network output to calibrate a model?

Thanks

[Edward_S_Intel1]

Yes, it's possible. Please explore:

• Readme file in package: intel/openvino/python/python3.5/openvino/tools/accuracy_checker/accuracy_checker/postprocessor/README.md
• Usage model here: https://docs.openvinotoolkit.org/latest/_inference_engine_tools_accuracy_checker_tool_README.html

Let me know if you still have any questions, please.

Hi Edward,

thanks you for reply, currently I have written own custom adapter, but I can't find how to make calibrator use it programatically. Calibration works if I add my detection adapter code at the end of /opt/intel/openvino/python/python3.5/openvino/tools/accuracy_checker/accuracy_checker/adapters/detection.py file, but I need to use it without such "tricks".

Maybe I missed any options by which I can link my adapter with calibrator?

Regards,

Aleksei

Can you please answer how can I use my custom adapter with calibration tool? Can't find any info in suggested sources.

Hi Aleksei,

Firstly, Calibration Tool uses Accuracy Checker to measure accuracy. Can you, please, explore existing adapters implementation and make in the same way: https://github.com/opencv/dldt/tree/2019/tools/accuracy_checker/accuracy_checker/adapters.

Note, please, the simplest way is: if your dataset structure is different then you can reorganize your dataset to well known and reuse existing adapters.

Best regards,

Edward
