Description

Can we just change

https://github.com/kohya-ss/sd-scripts/blob/cd19df49cd512e13ac90db115c424d19c0e8868a/library/train_util.py#L2209

To
_cv2.INTER_LANCZOS4_
on this line in this file so that the lanczos4 algorithm is used to downscale the size of the training images?

Research direction

Start at the referenced line 2209 in library/train_util.py and inspect how cv2 resamples training images during downscaling. Check whether the proposed interpolation constant is appropriate for this path; done means the requested Lanczos4 behavior is either implemented there or the question is answered with evidence from the existing code.
