Suboptimal interpolation when training the detail predictor

[MarkTension]

Hello, thank you for sharing your code!
I'd like to bring your attention to how F.interpolate is being used for training the detail predictor, in line:
https://github.com/edward1997104/Wavelet-Generation/blob/main/trainer/trainer.py#L260C33-L260C46

The interpolation mode is not set, and defaults to 'linear'. Setting mode='trilinear' gives better results (because it uses the 3 spatial dimensions instead of 1) and gets rid of some of the artifacts that I see in the results. Cheers!

EDIT: Sorry, it defaults to 'nearest', but still I think 'trilinear' is more desirable.

Oh... It is really nice for you to find out that as we used to consider this a design decision! We might test it out later to provide an updated model!
