@AlexKoff88
#156 just got merged regarding ONNX exporting. It may allow this PR to be simplified due to the large overlap in changes. Furthermore, there was discussion regarding moving all code for exporting into a new exporters submodule: #156 (comment). This PR should follow suit, i.e. rebase/merge main and move the functionality and tests to the exporters folders, respectively.

Hi Tom,

I've revised the code according to the recent changes and your suggestions. Please check again.

Hello @AlexKoff88,

I think we're moving in the right direction with these recent changes, but there are some issues still. openvino>=2022.3 cannot be installed. This is likely because 2022.3.0 only has pre-releases at the moment, as can be seen on its PyPI. Perhaps we can make this a bit more lenient with >=2022.2?` I'm unsure whether the latest pre-release version introduces must-have functionality for our purposes.

Beyond that, the CI is complaining about code quality. That can be resolved by running ./make style, which runs black and isort on most of the files in the project.

Hi,

I cleaned up the style.

OpenVINO 2022.3 is essential. I am ok to postpone the merge 1-2 weeks before it is available on PyPI.

[AlexKoff88]

@tomaarsen, OpenVINO 2022.3 is available and OpenVINO export should work now. Please merge.

@AlexKoff88 I still have some tiny nits on the notebook that you've provided. Thanks a lot for it, by the way, it helps users out a lot.
As for the actual code, it looks good. I'll merge this when the notebook is updated!
