Spletpytorch常用normalization函数. 将输入的图像shape记为，这几个方法主要的区别就是在， batchNorm是在batch上，对NHW做归一化，对小batchsize效果不好； layerNorm在通道方向上，对CHW归一化，主要对RNN作用明显； instanceNorm在图像像素上，对HW做归一化，用在风格化迁移； SpletBy default, this layer uses instance statistics computed from input data in both training and evaluation modes. If track_running_stats is set to True, during training this layer keeps …
