LinfinityBrendelBethgeAttack Goes Into Infinite Loop

[mehussein]

Hi,

I am only giving it a batch of 64 images with starting points that I test first and make sure they are all adversarial. But, sometimes, it gets stuck for too long, which I assume due to an infinite loop. If you are already aware of this, is there a way to configure the attack object to avoid it?

Best,

Thanks for the report. I am not aware of an infinite loop. If you starting point is not adversarial, you'll get an error right away. Do you also have problems if you set the number of iterations to 20?

Sorry that I missed your response. I set the number of steps to 10. I provide starting points by running PGD with eps 1 and only use the samples with successful attacks from PGD.
