Data augmentation for numpy images

My image data is in numpy format (npz files). These represent 3d images. I would like to apply data augmentation.
Any way to do this? Even a “custum preprocessing python script” would help, as there are enough suitable numpy tools to achieve the neccessary…
Consider this a feature request :wink: if it isn’t already possible.

Yes for now in DLS you can apply data augmentation on 2-d images.
Sure we will keep this in mind for future release.
Thank you
