ONNX stands for Open Neural Network Exchange.
It is an open-source artificial intelligence ecosystem that establishes open standards for representing machine learning algorithms and software tools to promote innovation and collaboration in the AI sector. It defines a common set of operators and a common file format for machine learning models.
What is ONNX Runtime?
ONNX Runtime (ORT) is a cross-platform, high performance ML inferencing and training accelerator that can optimize and accelerate machine learning process. It supports a variety of frameworks, operating systems, hardware platforms and accelerators. It can also run ONNX models, which are an open standard format for representing machine learning models.
