This repository contains the code and data for the paper "An Image Is Worth 1000 Lies: Transferability of Adversarial Images across Prompts on Vision-Language Models" accepted by ICLR 2024.

Overview

Overview of CroPA

Requirements

The environment.yml file contains the necessary packages to run the code. You can create the environment using the following command:

conda env create -f environment.yml

We provided a customized version of the Huggingface's transformers library. The code is based on the transformers library version 4.33.2.

Train

To obtain the perturbation, you can use the following command:

python main.py --model_name {VLM_NAME} --prompt_num {NUM_OF_PROMPTS} 

Inference

We provide the pretrained perturbation in the model/ directory. To run the inference, you can use the following command:

python inference.py  --noise_dir /path/to/perturbation

Pretrained perturbation can be found here: https://1drv.ms/u/c/4f881fa19ba8dfee/ERYe-4sAhPVEqbujubnuWxUByYtM676mnW8FQzaBkxtF-w?e=bIeOCh
