🐛 Bug We find the result of the InstanceNorm and batchnorm will get the same result when set track_running_stats=True and use model.eval(). Since instancenorm 2d is doing normalization to each images whereas batchnorm is doing it to whol...

# coding;utf8 import torch from torch import nn # track_running_stats=False,求当前 batch 真实平均值和标准差, # 而不是更新全局平均值和标准差 # affine=False, 只做归一化,不乘以 gamma 加 beta(通过训练才能确定) # num_features 为 feature map 的 channel 数目 # eps 设为 0,让官方代码和我们...

by setting track_running_stats=True. Background to why I am bumping this: I am exporting a PyTorch model to ONNX and I am given a warning about instance normalization layer being in training mode despite putting the model in evaluation mode. Result is that inference results differ from ...
