In this video, I show you how to accelerate Transformer inference with Optimum, an open source library by Hugging Face, and ONNX.

I start from a DistilBERT model fine-tuned for text classification, export it to ONNX format, then optimize it, and finally quantize it. Running benchmarks on an AWS c6i instance (Intel Ice Lake architecture), we speed up the original model more than 2.5x and divide its size by 50%, with just a few lines of simple Python code and without any accuracy drop!
