This tutorial is 5 years old and it seems it doesn't work as expected.

It seems it expects data in folder

/root/.keras/datasets/flower_photos/

but (using !ls -al /root/.keras/datasets/) I found it in

/root/.keras/datasets/flower_photos.tgz/flower_photos/

So it needs

# data_dir = pathlib.Path(archive).with_suffix('')
data_dir = pathlib.Path(archive) / 'flower_photos'

After this change next lines work.

EDIT:

It seems someone reported this problem half year ago. Maybe it will be fixed.
