Which file and class is the L2 norm attack?

[machanic]

How to support L2 norm attack? I can only find Sign_OPT_lf.py as the Linf norm attack?

Is Sign_OPT.py and class OPT_attack_sign_SGD the L2 norm attack??

[cmhcbb]

Yes, Sign_OPT.py is the l2 version. You could check test_attack.py for the example to run the attack.

@cmhcbb What is Sign_OPT_v2.py used for? It is not the file of L2 norm and L-inf norm attack? Then what is it?

[cmhcbb]

It's a file for debugging purposes.
