WebJun 8, 2024 · The Pytorch QAT operations matches with that of TIDL. TIDL will quantize the onnx model and use it for inference. So the TIDL output will be similar to that of PyTorch (but note that this is not an exact bitmatch, but sufficient to achieve good accuracy). So if you run that QAT onnx model in onnxruntime, it will not generate the expected output. WebApr 8, 2024 · The QAT API provides a simple and highly flexible way to quantize your TensorFlow Keras model.

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. WebJun 16, 2024 · The main idea behind QAT is to simulate lower precision behavior by minimizing quantization errors during training. To do that, you modify the DNN graph by adding quantize and de-quantize (QDQ) nodes around desired layers.
