ParaView now has an ONNX plugin to compute inference from an ONNX model, thanks to the ONNX Predict filter.

ONNX is a community project supported by the Linux Foundation, working toward interoperability of AI tools https://onnx.ai/about.html

Developer notes

To use ONNX with a local build of Paraview, you will have to install an ONNX runtime for C++ API https://onnxruntime.ai/

Note that due to some issue in the ONNX CMake integration with ONNX runtime 1.22.0 on linux you will need to:

• create a "lib64" link to the "lib" directory next to it. https://github.com/microsoft/onnxruntime/issues/25242
• move the lib/*.h files under an "onnxruntime" subdirectory (to create) https://github.com/microsoft/onnxruntime/issues/25279
