description Overview

ONNX

ONNX (Open Neural Network Exchange) isn't a deep learning framework itself, but an open standard for representing machine learning models. It allows models trained in one framework (e.g., PyTorch) to be deployed in another (e.g., TensorFlow or a custom inference engine). This interoperability is crucial for maximizing deployment flexibility and leveraging specialized hardware. ONNX simplifies the...

ONNX Runtime

ONNX Runtime is a high-performance inference engine designed to accelerate deep learning model deployment across various platforms. It supports the ONNX (Open Neural Network Exchange) format, enabling interoperability between different frameworks. ONNX Runtime's optimizations and hardware acceleration capabilities ensure efficient inference on CPUs, GPUs, and other specialized hardware. Its cross-...
