Onnx interop Key features and brief samples.
Nd4j allows execution of models via onnx runtime using nd4j's INDArray as a data structure. Leveraging the nd4j-onnxruntime interop is fairly simple. An onnx model can be loaded and executed as follows:
This outputs a result with a map of output names to the ndarray result from onnx.
In maven, add the following dependency:
Note, this depends on javacpp's onnxruntime bindings. This means onnx runtime's native binaries are managed by javacpp. Javacpp will bundle all native binaries for all platforms by default unless you specify a platform. You can do this by specifying a -Dplatform=your-platform-of-choice. You may find more here in the javacpp docs.
