ONNX, an LF AI & Data Foundation Graduated Project, has released version 1.9! ONNX is an open format to represent deep learning models. With ONNX, AI developers can more easily move models between state-of-the-art tools and choose the combination that is best for them. 

In version 1.9, ONNX adds a variety of improvements. Highlights include

  • Selective schema loading of specific operator set versions to reduce memory usage in runtimes
  • New and updated operators to support more data types and models including advanced object detection models like MobileNetV3, YOLOv5
  • Improved tools for splitting large, multi-GB models into separate files
  • More details and sample tests added to operator documentation
  • Version converter enhanced to make it easier to upgrade models to newer operator sets
