Hi, Jihoon! In the original paper, we did the upsampling after the first multi-scale block, but as far as I remember, this choice was quite arbitrary and the model performed more-or-less the same regardless of the block idx you choose to do the upsampling in.
In the current implementation, the superresolution is not implemented, I will take a look at it next week. I believe the most reasonable place to incorporate it is before the first block, i.e. in the CoordsInput layer. But this would require to change some misc.assert_shape(...)
statements and interpolate static positional embeddings to match the required image size (otherwise, it will fail here).

Thank you so much for the detailed response and the clarification!
