Convert Transformers to ONNX with Hugging Face Optimum

This post details how to convert Hugging Face Transformers models to the ONNX format using the Hugging Face Optimum library. It explains the benefits of ONNX for deployment and provides three methods for conversion: low-level `torch.onnx.export`, mid-level `transformers.onnx.export`, and high-level `optimum.onnxruntime.ORTModelForXxx.from_pretrained`. It also lists supported architectures and suggests next steps like accelerated inference, quantization, and training with ONNX.
