How do we use this in Elixir with Axon?

ONNX

Open Neural Network Exchange

  • Export yolov8n to ONNX
  • Import using axon_onnx
  • Run on an image
  • Visualize results

Steps:

You still need to understand the model

axon_onnx makes it easy to import and run ML models!

Nx is really useful for manupulating data!
