About the model FLOPs and Parameters

[OCEANOUXIN]

Hi Fabian, thanks for your excellent works! But I get few confusion. I worte a UNet.py code following your code(the same configurtion), i think i did not write wrong, but i get the following:


I don't why your model FLOPs and Parameters more than mine.

Hi @OCEANOUXIN ,

this could have many reasons, but generally the U-Net topology in nnunet is also adapted to the dataset at hand. This means that depending on the dataset you will get different U-Nets with different amounts of parameters etc.

Thanks for your earily reply,@seziegler. But I used the same input for both of tow models,as following:


There is a problem with profile module. I don't know whether the nnunet has the other not used modules and profile module also calculate the parts.Or maybe we should only calculate the input stream.

You can check the exact architecture of the two models to see where they differ by using print(model)

Yes, I accturally did it. Then I find this in nnunet:

I don't know why the tow parts are the same. How do they work? Whether both of they is useful? Thanks for your reply.
