Hi , I have just met a paroblem with nn.BatchNorm2d layer
due some reasons, I have to copy one BN-layer’s weight to an other . when I do this I just do like
layer1.weight.data = layer2.weight.data
layer1.bais.data = layer2.bias.data


and after doing this , I check these two layer’s weight and bias , they are same.
and also, when print this two layers , they are both shown as

BatchNorm2d(16,eps=1e-05,momentum =0.1,affine = True,track_running_state = True)

However, when I put the same input to these two layers, the outputs of them are different!
I  am not clear about  what’s wrong, what other parts should I check about these two layers?
thank you very much.
