@Thunder-29 could you try the same protobuf version with openvino?

Maybe you can try export the protobuf path into LD_LIBRARY_PATH.

@Thunder-29 you can follow this wiki to build openvino: https://github.com/openvinotoolkit/openvino/wiki#how-to-build but I'm not sure whether it still works for 2021.4. If any build issue please ping me.

@ilya-lavrenov CI failure is unrelated to the PR, could you help trigger to rerun ie_tests_stress_ubuntu20_release？Thanks！

You can try the openvino 2022.2 or latest master branch.

@awayzjj thank your PR, we have some comments please help resolve them. Supposed the validate function is only called by `ov::CoreImpl::compile_model`, put it into `core_impl.cpp` is ok.
