Resized or is it croppted

When you do:
tfms=tfms_from_model(arch, sz)
is the data/images “resize” to the square sz-BY-sz or is the images “center-center cropped”?

Resized.

Barashe, thanks for the response, but actually, the full answer is resize to the specify dimension with keeping the picture original ratio, then square-center-crop to the specify size.
