model.fuse() vs re-parameterization ?

[mhcho0110]

What's the difference model.fuse() and reparameterization of below link?

I have the same question.

As far as I can see, fuse methods are present, but they are not used anywhere, except here

For yolov7 model in provided notebook only Detect head is fused, but 'Conv' with BatchNormalization are don't.

It seems, model.fuse() is not implemented alternative to manual reparameterization

Any conclusion on this? From what I understand the reparameterisation given in the repameterization.ipynb is like copying the weights of ema. And its different from the one mentioned in the paper.
