Application of EPro-PnP？

[BoBoINVICTUS]

I wonder if EPro-PnP can only be applied to one-stage networks, and if it can be applied to some two-stage pose estimation networks, such as PVNet.

Applying EPro-PnP on two-stage networks could be tricky, unless you could make it end-to-end differentiable (e.g., differentiable pixel voting in PVNet).
