Thank you for your valuable information, this is very helpful.  It seems that the bicubic interpolation plays an important role. I also tested the ResNet pretrained models, they are perfectly matched with the paper’s results.  And according to what you shown, even with bicuib interpolation, the current version of DenseNet is still under 77. Does it mean that there isn’t any place to find a better base that fits the original 77.2 result on Pytorch as of now?
