Misunderstanding for HarDBlock

[TommyHuang821]

Hi

I generated the HarDNet68ds.onnx, and visualized the network structure in Netron.
I make a similar figure, which is referenced by result of Netron, with your paper, and try to figure out the same structure.
Please see the belowing figure, it's almost similar.
Layer 8 connected with $8-2^n$ ($8/2^n$), so n=0,1,2,3
Hence, layer 8 connected with layers 7,6,4,0 (Blue line)
But I can't find the connection between "input layer" and "Next Block" (please see the orange lines).
I also trace the code, and can't find any evidence about the connection between input layer and Next block.
Can you help me figure out this problem?

Many thanks,
Tommy

Hello Tommy,
Thank you very much for your feedback. Yes, you are totally right. We actually have two different versions of HarDNet. The old one has this block-level shortcut link for a fair comparison purpose to align with DenseNet. The architecture in this repo is actually a new version without this shortcut. Sorry for the confusion. Please let me know if any. Thanks!
