[Torchattacks](https://adversarial-attacks-pytorch.readthedocs.io/en/latest/index.html) is a PyTorch library that provides *adversarial attacks* to generate *adversarial examples*. It contains *PyTorch-like* interface and functions that make it easier for PyTorch users to implement adversarial attacks ([README [KOR]](https://github.com/Harry24k/adversairal-attacks-pytorch/blob/master/README_KOR.md)).


```python
import torchattacks
atk = torchattacks.PGD(model, eps=8/255, alpha=2/255, steps=4)
# If, images are normalized:
# atk.set_normalization_used(mean=[...], std=[...])
adv_images = atk(images, labels)
```

## Requirements and Installation

### :clipboard: Requirements

- PyTorch version >=1.4.0
- Python version >=3.6



### :hammer: Installation

```
pip install torchattacks
```


## Getting Started

###  :warning: Precautions
* **All models should return ONLY ONE vector of `(N, C)` where `C = number of classes`.** Considering most models in _torchvision.models_ return one vector of `(N,C)`, where `N` is the number of inputs and `C` is thenumber of classes, _torchattacks_ also only supports limited forms of output.  Please check the shape of the model’s output carefully. 
* **`torch.backends.cudnn.deterministic = True` to get same adversarial examples with fixed random seed**. Some operations are non-deterministic with float tensors on GPU [[discuss]](https://discuss.pytorch.org/t/inconsistent-gradient-values-for-the-same-input/26179). If you want to get same results with same inputs, please run `torch.backends.cudnn.deterministic = True`[[ref]](https://stackoverflow.com/questions/56354461/reproducibility-and-performance-in-pytorch).



### :rocket: Demos

#### Torchattacks supports following functions:

<details><summary>Targeted mode</summary><p>

* Random target label:
```python
# random labels as target labels.
atk.set_mode_targeted_random(n_classses)
```

* Least likely label:
```python
# label with the k-th smallest probability used as target labels.
atk.set_mode_targeted_least_likely(kth_min)
```

* By custom function:
```python
# label from mapping function
atk.set_mode_targeted_by_function(target_map_function=lambda images, labels:(labels+1)%10)
```

* Return to default:
```python
atk.set_mode_default()
```

</p></details>

<details><summary>Return type</summary><p>

* Return adversarial images with integer value (0-255).
```python
atk.set_return_type(type='int')
```

* Return adversarial images with float value (0-1).
```python
atk.set_return_type(type='float')
```

</p></details>

<details><summary>Save adversarial images</summary><p>

```python
# Save
atk.save(data_loader, save_path="./data.pt", verbose=True)

# Load
adv_loader = atk.load(load_path="./data.pt")
```

</p></details>

<details><summary>Training/Eval during attack</summary><p>

```python
# For RNN-based models, we cannot calculate gradients with eval mode.
# Thus, it should be changed to the training mode during the attack.
atk.set_training_mode(model_training=False, batchnorm_training=False, dropout_training=False)
```

</p></details>


<details><summary>Make a set of attacks</summary><p>

* Strong attacks
```python
atk1 = torchattacks.FGSM(model, eps=8/255)
atk2 = torchattacks.PGD(model, eps=8/255, alpha=2/255, iters=40, random_start=True)
atk = torchattacks.MultiAttack([atk1, atk2])
```

* Binary search for CW
```python
atk1 = torchattacks.CW(model, c=0.1, steps=1000, lr=0.01)
atk2 = torchattacks.CW(model, c=1, steps=1000, lr=0.01)
atk = torchattacks.MultiAttack([atk1, atk2])
```

* Random restarts
```python
atk1 = torchattacks.PGD(model, eps=8/255, alpha=2/255, iters=40, random_start=True)
atk2 = torchattacks.PGD(model, eps=8/255, alpha=2/255, iters=40, random_start=True)
atk = torchattacks.MultiAttack([atk1, atk2])
```

</p></details>



#### Torchattacks also supports collaboration with other attack packages.

## Performance Comparison

For a fair comparison, [Robustbench](https://github.com/RobustBench/robustbench) is used. As for the comparison packages, currently updated and the most cited methods were selected:

* **Foolbox**: [505](https://scholar.google.com/scholar?q=Foolbox%3A%20A%20Python%20toolbox%20to%20benchmark%20the%20robustness%20of%20machine%20learning%20models.%20arXiv%202018) citations and last update 2022.10.
* **ART**: [262](https://scholar.google.com/scholar?cluster=5391305326811305758&hl=ko&as_sdt=0,5&sciodt=0,5) citations and last update 2022.10.

Robust accuracy against each attack and elapsed time on the first 50 images of CIFAR10. For L2 attacks, the average L2 distances between adversarial images and the original images are recorded. All experiments were done on GeForce RTX 2080.

<sup>*</sup> Note that Foolbox returns accuracy and adversarial images simultaneously, thus the *actual* time for generating adversarial images  might be shorter than the records.

<sup>**†**</sup>Considering that the binary search algorithm for const `c` can be time-consuming, torchattacks supports MutliAttack for grid searching `c`.
