with different kernel sizes ,feature maps also have different size ,like (1,1,62,62）and (1,1,67,67), in such condition, torch.cat doesn’t work as their dimensions don’t match. is there any way can make them together? Thanks a lot
I don’t think so 
You can always flatten them to (1,-1) where -1=62x62 or 67x67.
Otherwise you’re stuck with padding or cropping the feature maps
it works. great appreciated
