Nettet6. des. 2024 · PyTorch allows you to simulate quantized inference using fake quantization and dequantization layers, but it does not bring any performance benefits over FP32 inference. As of PyTorch 1.90, I think PyTorch has not supported real quantized inference using CUDA backend. To run quantized inference, specifically INT8 inference, please … NettetCopy to clipboard. torch.nn.init.dirac_(tensor, groups=1) [source] Fills the {3, 4, 5}-dimensional input Tensor with the Dirac delta function.

Nettet传统意义上的量化即为将连续信号转换为离散信号,在神经网络的量化中,即将浮点数float32→int8,int4,int2等,缩小可表示的空间大小。 量化其本质就是低精度low precision,常规精度一般使用FP32存储模型全中,低精度则表示FP16,或INT8等等数值格式,不过目前低精度往往指的就是INT8。 在tensorflow2.0之后的版本中提供了Mixed …
