trainning和track_running_stats,track_running_stats=True表示跟踪整个训练过程中的batch的统计特性,得到方差和均值,而不只是仅仅依赖与当前输入的batch的统计特性。相反的,如果track_running_stats=False那么就只是计算当前输入的batch的统计特性中的均值和方差了。当在推理阶段的时候,如果track_running_stats=False,此时如...
在旧版本的 PyTorch 中,BatchNorm2d类在训练过程中通过设置track_running_stats=True来跟踪统计信息,例如均值和方差。但是在较新的版本中,BatchNorm2d类的track_running_stats参数默认为True,因此无需手动设置。 因此,当我们在较新版本的 PyTorch 中的代码中手动设置track_running_stats参数时,就会出现'BatchNorm2d' ...

接近，但bn不只是有mean和inv_var，你这么做把w和b也冻住了。看代码最清楚了：torch.nn.modules.bat...
Altered test_batchnorm2d to only assign and test the running stats when track_running_stats=True The track_running_stats of Pytorch's BatchNorm is properly set. Also possible combinations of parameters for test_batchnorm2d are tried (though probs not needed). To mimic pytorch, test_fold_conv...
🐛 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...
num_features:为输入的数据的通道数, eps:使分母不为零,保持数据的稳定 momentum:用于在训练时对均值和方差的估计 affine:为True时表示γ和β是可学习的参数,为False表示γ和β是不可学习的参数,此时γ=1,β=0; track_running_stats=True;整个batch的方差和均值...
