Hi, thank you for your great work.

The number of FLOPs and the numbers of parameters are less than Swin Transformer, however the training time of HRFormer is at least 2 times longer than Swin, and 3 times longer than HRNet.
I guess the gradient calculation is very long because of a lot of reshape operations ? Is there a way to optimize that ?

Thank you

@david-az Good question!

Currently, we do not have any plans or solutions to optimize the training time cost of HRFormer.
You can find that our HRFormer already chooses a much smaller network depth compared to the original HRNet.
Any suggestions on optimizing the training time are WELCOME!
