OV plugin does not load on Linux

[jcarrano]

I managed to get the OpenVino plugin to compile under Arch Linux after a few tweaks but VapourSynth is not loading it. The shared object is loaded according to strace, but vs reports:

AttributeError: No attribute with the name ov exists. Did you mistype a plugin namespace?

What is the procedure to debug this? I'm not familiar with VS development but I can try to debug it I'm given me some pointers.

Probably the dependency libtbb.so is not loaded?

First, ldd libvsov.so to see if all dependencies can be found.

Then, set LD_DEBUG=all and then run vspipe with a trivial vpy that load the plugin. The output on stderr might contain some pointers as to why the plugin fails to load.

Thanks for the support.

The so was not being linked against onnx (which for some reason is a static lib in my system). So I added -lonnx. Also, it was linking against protobuf-lite only, but it needed the protobuf with typeinfo, so I added -lprotobuf, and I messed around with the linking order and got it to work.

The GPU backend does not work. It says cldnn program build failed! Could not find entry point. CPU works but the performance is not worth it.

Did you fetch all submodules of openvino? Is OV_CPU faster than ORT_CPU?

[jcarrano]

Thanks, I did not have time to try OV vs ORT. I gave up when I realized that I wouldn't get far anyways with the intel GPU, so now I'm trying to compile the ONNXRuntime based one to use with cuda.

@jcarrano have you built the ONNXRuntime based one to use with cuda succefully?

@lu0se Is there any issue? I use ort_cuda+ov on linux, but I haven't upgraded to the latest version yet.

I tried to compile it on Arch Linux,but it failed when I compile protobuf,could you provide your compilation scripts?

[WolframRhodium]

What's the error? I do not have a fixed script and compile it manually, based on the workflow file.

when i compile openvivo,

/home/l/Code/openvino/thirdparty/ade/sources/ade/include/ade/typed_graph.hpp:101:10: 错误：‘uintptr_t’不是命名空间‘std’中的一个类型名
  101 |     std::uintptr_t m_srcGraph;
      |          ^~~~~~~~~

While this is indeed a strange issue, we do not compile openvino with opencv support.
