Hi,

Really depends on what you want to do with your images.

From the docs (https://docs.fast.ai/vision.augment.html#Resize)

The default for Resize() is to use
method ='crop' , pad_mode ='reflection' , resamples =(2, 0)

Use Resize(128) unless you want to do something else with the image. :slight_smile:
