WebQuantization is a technique that converts 32-bit floating numbers in the model parameters to 8-bit integers. With quantization, the model size and memory footprint can be reduced to 1/4 of its original size, and the inference can be made about 2-4 times faster, while the accuracy stays about the same.

WebQuantization Aware Training (QAT) improves accuracy of quantized networks by emulating quantization errors in the forward and backward passes during training. TensorRT 8.0 brings improved support for QAT with PyTorch, in conjunction with NVIDIA's open-source pytorch-quantization toolkit. WebSep 13, 2024 · Since PyTorch stores quantized tensors in a custom format that only PT understands, to extract 8 bit weight we have to first “unpack” the custom quantized tensor into float32, convert it to numpy and then back to int8 using a relay op. The conversion of weights back to int8 happens during relay.build (...). To see this, you can replace
