Input aware dynamic backdoor error

[GorkaAbad]

Hi!,
I wanted to know if when using the --attack input_aware_dynamic I also should provide some mask parameters. I assume that I don't have to since the trigger should be included throughout the image.

I'm running this:
python examples/backdoor_attack.py --color --verbose 1 --dataset cifar100 --model vgg11_bn --attack input_aware_dynamic --save --download --poison_percent 0.001 --epochs 100 --pretrained --output 1 --dataset_normalize --train_mask_epochs 1 --attack_dir res/

But I keep getting this error in /trojanvision/attacks/backdoor/dynamic/input_aware_dynamic.py", line 378, in attack:
UnboundLocalError: local variable 'loss_div' referenced before assignment

Thanks in advance.

Are you using the most up-to-date code?

[GorkaAbad]

Yes, I think so. I just installed the latest version from GitHub today.

Just commit a fix. Could you please try whether it works?

[GorkaAbad]

Thanks for the fast response. Yes, that problem its solved now.

Thanks for your report. The error is raised because of the low poison percent and there might be no poisoning data in a batch. I previously didn't take that into consideration.
