Hello, did anyone here get already solution? I have a model is trained on Pytorch 0.3 and I couldn’t afford to retrain on 0.4. I have the same problem that it is complained that the BatchNorm2d doesn’t have the attribute: “tracking_running_state”. Is this a way that I could filter out the module is BatchNorm and add this attribute myself? Or any better ideas? Thanks in advance. My model is saved the whole model.
