Pytorch 16 bit quantization
WebMar 8, 2024 · NNCF is a suite of advanced algorithms for optimizing machine learning and deep learning models for inference in the Intel® Distribution of OpenVINO TM toolkit. NNCF works with models from PyTorch and TensorFlow. One of the main features of NNCF is 8-bit uniform quantization, using recent academic research to create accurate and fast models.

WebFeb 21, 2024 · Recently I used pytorch quantization-aware training to quantize my model. The result still has good accuracy, and it uses per channel scales. However, our hardware colleagues told me that because it has FP scales and zero-points in channels, the hardware should still support FP in order to implement it.
