Inconsistent size between output and target about hrnet-semantic-segmentation

I have the same confusion !
Before the Bottleneck, 2 convolution layers with stride 2 make the input down sample 4x. Should I up sample 4x after the final layer to recover the input size or change the stride of the first two convolution layer into 1 ?

I guess you might wanna check out other issues, the similar questions have been asked for a few times. But, my question is, put the bilinear upsampling layer before the final layer or after? cuz I believe if the final output comes from a bilinear upsampling layer, the output has to be a bit coarse.

Based on the author's reply here, it seems to be bilinear interpolation upsampling after the output

Thanks for your reply. I've seen the issue. But it seems to be a little coarse to bilinear 4x to predict directly. I want to know whether you have some solutions to address it?
