ONNX-GO Neural Networks made easy dotGO - March 25th 2019 Olivier Wulveryck Octo Technology @owulveryck

Software has changed the world! We, as developers, are actors of this evolution.

- I want to give my code super power! - I want to use it to predict Y, given X! - Use machine learning Luke! iota

SHOW ME SOME CODE! ONNX-GO (MNIST) example backend := gorgonia.NewGraph() model := onnx.NewModel(backend) Create the execution backend (Gorgonia) and the onnx model receiver b, err := ioutil.ReadFile("model.onnx") err = model.Unmarshal(b) Read the onnx file and Deserialize it into the model receiver gorgonia.NewTapeMachine(backend).RunAll() output := getData(model.Output[0]) // []float32 Run the backend to compute the result var picture *image.NRGBA setData(model.Input[0],picture) Set the input

DEMO of the POC # Get the model: curl https://www.cntk.ai/OnnxModels/mnist/opset_7/mnist.tar.gz | tar -C /tmp -xzvf - # Get the demo binary from https://github.com/owulveryck/onnx-go/releases/tag/v0.1-mnist-cli # Run it: ../mnist-reader.darwin -model /tmp/mnist/model.onnx

Imagine what you, as a Gopher, can do with Machine Learning. Get involve, nobody is a nobody! github.com/onnx/models github.com/owulveryck/onnx-go gorgonia.org/gorgonia

Let's make programming (with) Neural networks fun (again) Welcome to software 2.0 with GO! Thank you! @owulveryck
