ONNX
ONNX (The Open Neural Network Exchange) is an AI ecosystem that created standards for representing machine learning algorithms. These standards allow ONNX machine learning algorithms to be run on a wide variety of machines (unfortunately excluding Apple).
ONNX supports a wide variety of frameworks, including Matlab, Keras, TensorFlow, and PyTorch. For a full list and detailed instructions on converting to and from ONNX models, see this page: https://onnx.ai/supported-tools.html
Instructions for converting a TensorFlow model to ONNX:
ONNX Runtime
ONNX does not itself perform inference. To do that, you need to install a runtime that can run ONNX. Use the following website for installation and operation instructions: https://onnxruntime.ai/index.html#getStartedTable
Using this, you can perform inference up to 17x faster. ONNX Runtime also allows you to accelerate PyTorch training (only PyTorch so far) up to 40% faster.
