This is an extremely thin convenience wrapper (just 40 lines of code) to load Foolbox-native attacks in Cleverhans 4 (currently both in beta as of 10.01.2020).
Even without this wrapper, it should generally be possible to switch between the two frameworks with minimal changes to your code.
pip install cleverfool
import foolbox.ext.native as fbn
from cleverfool import convert_foolbox_attack
attack = convert_foolbox_attack(fbn.attacks.LinfinityBasicIterativeAttack)
# ... use attack just like any other CleverHans attack
