# 👋 Introduction

Anomalib is a deep learning library that aims to collect state-of-the-art anomaly detection algorithms for benchmarking on both public and private datasets. Anomalib provides several ready-to-use implementations of anomaly detection algorithms described in the recent literature, as well as a set of tools that facilitate the development and implementation of custom models. The library has a strong focus on visual anomaly detection, where the goal of the algorithm is to detect and/or localize anomalies within images or videos in a dataset. Anomalib is constantly updated with new algorithms and training/inference extensions, so keep checking!

</p>

## Key features

- Simple and modular API and CLI for training, inference, benchmarking, and hyperparameter optimization.
- The largest public collection of ready-to-use deep learning anomaly detection algorithms and benchmark datasets.
- [**Lightning**](https://www.lightning.ai/) based model implementations to reduce boilerplate code and limit the implementation efforts to the bare essentials.
- The majority of models can be exported to [**OpenVINO**](https://www.intel.com/content/www/us/en/developer/tools/openvino-toolkit/overview.html) Intermediate Representation (IR) for accelerated inference on Intel hardware.
- A set of [inference tools](tools) for quick and easy deployment of the standard or custom anomaly detection models.

# 📦 Installation

Anomalib provides multiple installation options to suit your needs. Choose the one that best fits your requirements:

## 🚀 Install from PyPI

```bash
# Basic installation from PyPI
pip install anomalib

# Full installation with all dependencies
pip install anomalib[full]
```

## 🔧 Install from Source

For contributing or customizing the library:

```bash
git clone https://github.com/open-edge-platform/anomalib.git
cd anomalib
pip install -e .

# Full development installation with all dependencies
pip install -e .[full]
```

# 🧠 Training

Anomalib supports both API and CLI-based training approaches:

## 🔌 Python API

```python
from anomalib.data import MVTecAD
from anomalib.models import Patchcore
from anomalib.engine import Engine

# Initialize components
datamodule = MVTecAD()
model = Patchcore()
engine = Engine()

# Train the model
engine.fit(datamodule=datamodule, model=model)
```

## ⌨️ Command Line

```bash
# Train with default settings
anomalib train --model Patchcore --data anomalib.data.MVTecAD

# Train with custom category
anomalib train --model Patchcore --data anomalib.data.MVTecAD --data.category transistor

# Train with config file
anomalib train --config path/to/config.yaml
```

# 🤖 Inference

Anomalib provides multiple inference options including Torch, Lightning, Gradio, and OpenVINO. Here's how to get started:

## 🔌 Python API

```python
# Load model and make predictions
predictions = engine.predict(
    datamodule=datamodule,
    model=model,
    ckpt_path="path/to/checkpoint.ckpt",
)
```

## ⌨️ Command Line

```bash
# Basic prediction
anomalib predict --model anomalib.models.Patchcore \
                 --data anomalib.data.MVTecAD \
                 --ckpt_path path/to/model.ckpt

# Prediction with results
anomalib predict --model anomalib.models.Patchcore \
                 --data anomalib.data.MVTecAD \
                 --ckpt_path path/to/model.ckpt \
                 --return_predictions
```

> 📘 **Note:** For advanced inference options including Gradio and OpenVINO, check our [Inference Documentation](https://anomalib.readthedocs.io).

# Training on Intel GPUs

> [!Note]
> Currently, only single GPU training is supported on Intel GPUs.
> These commands were tested on Arc 750 and Arc 770.

Ensure that you have PyTorch with XPU support installed. For more information, please refer to the [PyTorch XPU documentation](https://pytorch.org/docs/stable/notes/get_start_xpu.html)

## 🔌 API

```python
from anomalib.data import MVTecAD
from anomalib.engine import Engine, SingleXPUStrategy, XPUAccelerator
from anomalib.models import Stfpm

engine = Engine(
    strategy=SingleXPUStrategy(),
    accelerator=XPUAccelerator(),
)
engine.train(Stfpm(), datamodule=MVTecAD())
```

## ⌨️ CLI

```bash
anomalib train --model Padim --data MVTecAD --trainer.accelerator xpu --trainer.strategy xpu_single
```

# ⚙️ Hyperparameter Optimization

Anomalib supports hyperparameter optimization (HPO) using [Weights & Biases](https://wandb.ai/) and [Comet.ml](https://www.comet.com/).

```bash
# Run HPO with Weights & Biases
anomalib hpo --backend WANDB --sweep_config tools/hpo/configs/wandb.yaml
```

> 📘 **Note:** For detailed HPO configuration, check our [HPO Documentation](https://openvinotoolkit.github.io/anomalib/tutorials/hyperparameter_optimization.html).

# 🧪 Experiment Management

Track your experiments with popular logging platforms through [PyTorch Lightning loggers](https://pytorch-lightning.readthedocs.io/en/stable/extensions/logging.html):

- 📊 Weights & Biases
- 📈 Comet.ml
- 📉 TensorBoard

Enable logging in your config file to track:

- Hyperparameters
- Metrics
- Model graphs
- Test predictions

> 📘 **Note:** For logging setup, see our [Logging Documentation](https://openvinotoolkit.github.io/anomalib/tutorials/logging.html).

# 📊 Benchmarking

Evaluate and compare model performance across different datasets:

```bash
# Run benchmarking with default configuration
anomalib benchmark --config tools/benchmarking/benchmark_params.yaml
```

> 💡 **Tip:** Check individual model performance in their respective README files:
>
> - [Patchcore Results](src/anomalib/models/image/patchcore/README.md#mvtec-ad-dataset)
> - [Other Models](src/anomalib/models/)
