Pytorch量化工具 方式一:Post Training Dynamic Quantization(PTDQ), 模型训练完毕后的动态量化 动态量化函数 torch.quantization.quantize_dynamic( model, qconfig_spec=None, dtype=torch.qint8, mapping=None, inplace=False) 可实现对某些层进行量化,量化后的模型只能用于推理验证,不能用作训练。其中参数详解如下...
PyTorch is a framework to implement deep learning, so sometimes we need to compute the different points by using lower bit widths. At that time we can use PyTorch quantization. Basically, quantization is a technique that is used to compute the tensors by using bit width rather than the float...
