ONNX, Runtime, Backends
=======================

*mlprodict* implements two runtimes.
The first uses :epkg:`numpy` and implements
mathematical functions defined by :epkg:`ONNX`.
The second one leverages :epkg:`onnxruntime` to
compute the output of every node using
:epkg:`onnxruntime` but :epkg:`python` stills handles the graph
logic. A last one just wraps :epkg:`onnxruntime` to compute
predictions, it handles the graph and operators runtimes.
