[![Downloads](https://static.pepy.tech/badge/ultralytics)](https://pepy.tech/project/ultralytics)
[![PyPI - Python Version](https://img.shields.io/pypi/pyversions/ultralytics?logo=python&logoColor=gold)](https://pypi.org/project/ultralytics/)
To install the ultralytics package in developer mode, ensure you have Git and Python 3 installed on your system. Then, follow these steps:
1. Clone the ultralytics repository to your local machine using Git:
```bash
git clone https://github.com/ultralytics/ultralytics.git
```
2. Navigate to the cloned repository's root directory:
```bash
cd ultralytics
```
3. Install the package in developer mode using pip (or pip3 for Python 3):
```bash
pip install -e '.[dev]'
```
- This command installs the ultralytics package along with all development dependencies, allowing you to modify the package code and have the changes immediately reflected in your Python environment.
## 🚀 Building and Serving Locally
The `mkdocs serve` command builds and serves a local version of your MkDocs documentation, ideal for development and testing:
```bash
mkdocs serve
```
- #### Command Breakdown:
- `mkdocs` is the main MkDocs command-line interface.
- `serve` is the subcommand to build and locally serve your documentation.
- 🧐 Note:
- Grasp changes to the docs in real-time as `mkdocs serve` supports live reloading.
- To stop the local server, press `CTRL+C`.
## 🌍 Building and Serving Multi-Language
Supporting multi-language documentation? Follow these steps:
1. Stage all new language \*.md files with Git:
```bash
git add docs/**/*.md -f
```
2. Build all languages to the `/site` folder, ensuring relevant root-level files are present:
```bash
# Clear existing /site directory
rm -rf site
# Loop through each language config file and build
mkdocs build -f docs/mkdocs.yml
for file in docs/mkdocs_*.yml; do
echo "Building MkDocs site with $file"
mkdocs build -f "$file"
done
```
3. To preview your site, initiate a simple HTTP server:
```bash
cd site
python -m http.server
# Open in your preferred browser
```
- 🖥️ Access the live site at `http://localhost:8000`.
## 📤 Deploying Your Documentation Site
Choose a hosting provider and deployment method for your MkDocs documentation:
- Configure `mkdocs.yml` with deployment settings.
- Use `mkdocs deploy` to build and deploy your site.
* ### GitHub Pages Deployment Example:
```bash
mkdocs gh-deploy
```
- Update the "Custom domain" in your repository's settings for a personalized URL.
![MkDocs deployment example](https://github.com/ultralytics/docs/releases/download/0/mkdocs-deployment-example.avif)
- For detailed deployment guidance, consult the [MkDocs documentation](https://www.mkdocs.org/user-guide/deploying-your-docs/).

# Ultralytics YOLO 🚀, AGPL-3.0 license
"""
Automates the building and post-processing of MkDocs documentation, particularly for projects with multilingual content.
It streamlines the workflow for generating localized versions of the documentation and updating HTML links to ensure
they are correctly formatted.
Key Features:
- Automated building of MkDocs documentation: The script compiles both the main documentation and
any localized versions specified in separate MkDocs configuration files.
- Post-processing of generated HTML files: After the documentation is built, the script updates all
HTML files to remove the '.md' extension from internal links. This ensures that links in the built
HTML documentation correctly point to other HTML pages rather than Markdown files, which is crucial
for proper navigation within the web-based documentation.
Usage:
- Run the script from the root directory of your MkDocs project.
- Ensure that MkDocs is installed and that all MkDocs configuration files (main and localized versions)
are present in the project directory.
- The script first builds the documentation using MkDocs, then scans the generated HTML files in the 'site'
directory to update the internal links.
- It's ideal for projects where the documentation is written in Markdown and needs to be served as a static website.
Note:
- This script is built to be run in an environment where Python and MkDocs are installed and properly configured.

# ImageWoof Dataset
The [ImageWoof](https://github.com/fastai/imagenette) dataset is a subset of the ImageNet consisting of 10 classes that are challenging to classify, since they're all dog breeds. It was created as a more difficult task for [image classification](https://www.ultralytics.com/glossary/image-classification) algorithms to solve, aiming at encouraging development of more advanced models.
## Key Features
- ImageWoof contains images of 10 different dog breeds: Australian terrier, Border terrier, Samoyed, Beagle, Shih-Tzu, English foxhound, Rhodesian ridgeback, Dingo, Golden retriever, and Old English sheepdog.
- The dataset provides images at various resolutions (full size, 320px, 160px), accommodating for different computational capabilities and research needs.
- It also includes a version with noisy labels, providing a more realistic scenario where labels might not always be reliable.
## Dataset Structure
The ImageWoof dataset structure is based on the dog breed classes, with each breed having its own directory of images.
## Applications
The ImageWoof dataset is widely used for training and evaluating deep learning models in image classification tasks, especially when it comes to more complex and similar classes. The dataset's challenge lies in the subtle differences between the dog breeds, pushing the limits of model's performance and generalization.
## Usage
To train a CNN model on the ImageWoof dataset for 100 [epochs](https://www.ultralytics.com/glossary/epoch) with an image size of 224x224, you can use the following code snippets. For a comprehensive list of available arguments, refer to the model [Training](../../modes/train.md) page.
!!! example "Train Example"
=== "Python"
```python
from ultralytics import YOLO
# Load a model
model = YOLO("yolo11n-cls.pt") # load a pretrained model (recommended for training)
# Train the model
results = model.train(data="imagewoof", epochs=100, imgsz=224)
```
=== "CLI"
```bash
# Start training from a pretrained *.pt model
yolo classify train data=imagewoof model=yolo11n-cls.pt epochs=100 imgsz=224
```
## Dataset Variants
ImageWoof dataset comes in three different sizes to accommodate various research needs and computational capabilities:
1. **Full Size (imagewoof)**: This is the original version of the ImageWoof dataset. It contains full-sized images and is ideal for final training and performance benchmarking.

from ultralytics import YOLO
# Load a model
model = YOLO("yolo11n-cls.pt") # load a pretrained model (recommended for training)
# For medium-sized dataset
model.train(data="imagewoof320", epochs=100, imgsz=224)
# For small-sized dataset
model.train(data="imagewoof160", epochs=100, imgsz=224)
```
=== "CLI"
```bash
# Load a pretrained model and train on the small-sized dataset
yolo classify train model=yolo11n-cls.pt data=imagewoof320 epochs=100 imgsz=224
```
It's important to note that using smaller images will likely yield lower performance in terms of classification accuracy. However, it's an excellent way to iterate quickly in the early stages of model development and prototyping.

# Image Classification Datasets Overview
### Dataset Structure for YOLO Classification Tasks
For [Ultralytics](https://www.ultralytics.com/) YOLO classification tasks, the dataset must be organized in a specific split-directory structure under the `root` directory to facilitate proper training, testing, and optional validation processes. This structure includes separate directories for training (`train`) and testing (`test`) phases, with an optional directory for validation (`val`).
Each of these directories should contain one subdirectory for each class in the dataset. The subdirectories are named after the corresponding class and contain all the images for that class. Ensure that each image file is named uniquely and stored in a common format such as JPEG or PNG.
**Folder Structure Example**
Consider the CIFAR-10 dataset as an example. The folder structure should look like this:
```
cifar-10-/
|
|-- train/
| |-- airplane/
| | |-- 10008_airplane.png
| | |-- 10009_airplane.png
| | |-- ...
| |
| |-- automobile/
| | |-- 1000_automobile.png
| | |-- 1001_automobile.png
| | |-- ...
| |
| |-- bird/
| | |-- 10014_bird.png
| | |-- 10015_bird.png
| | |-- ...
| |
| |-- ...
|
|-- test/
| |-- airplane/
| | |-- 10_airplane.png
| | |-- 11_airplane.png
| | |-- ...
| |
| |-- automobile/
| | |-- 100_automobile.png
| | |-- 101_automobile.png
| | |-- ...
| |
| |-- bird/
| | |-- 1000_bird.png
| | |-- 1001_bird.png
| | |-- ...
| |
| |-- ...
|
|-- val/ (optional)
| |-- airplane/
| | |-- 105_airplane.png
| | |-- 106_airplane.png
| | |-- ...
| |
| |-- automobile/
| | |-- 102_automobile.png
| | |-- 103_automobile.png
| | |-- ...
| |
| |-- bird/
| | |-- 1045_bird.png
| | |-- 1046_bird.png
| | |-- ...
| |
| |-- ...
```
This structured approach ensures that the model can effectively learn from well-organized classes during the training phase and accurately evaluate performance during testing and validation phases.
## Usage

=== "Python"
```python
from ultralytics import YOLO
# Load a model

# MNIST Dataset
The [MNIST](https://en.wikipedia.org/wiki/MNIST_database) (Modified National Institute of Standards and Technology) dataset is a large database of handwritten digits that is commonly used for training various image processing systems and machine learning models. It was created by "re-mixing" the samples from NIST's original datasets and has become a benchmark for evaluating the performance of image classification algorithms.
## Key Features
- MNIST contains 60,000 training images and 10,000 testing images of handwritten digits.
- The dataset comprises grayscale images of size 28x28 pixels.
- The images are normalized to fit into a 28x28 pixel [bounding box](https://www.ultralytics.com/glossary/bounding-box) and anti-aliased, introducing grayscale levels.
- MNIST is widely used for training and testing in the field of machine learning, especially for image classification tasks.
## Dataset Structure
The MNIST dataset is split into two subsets:
1. **Training Set**: This subset contains 60,000 images of handwritten digits used for training machine learning models.
2. **Testing Set**: This subset consists of 10,000 images used for testing and benchmarking the trained models.
## Extended MNIST (EMNIST)
Extended MNIST (EMNIST) is a newer dataset developed and released by NIST to be the successor to MNIST. While MNIST included images only of handwritten digits, EMNIST includes all the images from NIST Special Database 19, which is a large database of handwritten uppercase and lowercase letters as well as digits. The images in EMNIST were converted into the same 28x28 pixel format, by the same process, as were the MNIST images. Accordingly, tools that work with the older, smaller MNIST dataset will likely work unmodified with EMNIST.
## Applications
The MNIST dataset is widely used for training and evaluating [deep learning](https://www.ultralytics.com/glossary/deep-learning-dl) models in image classification tasks, such as [Convolutional Neural Networks](https://www.ultralytics.com/glossary/convolutional-neural-network-cnn) (CNNs), [Support Vector Machines](https://www.ultralytics.com/glossary/support-vector-machine-svm) (SVMs), and various other machine learning algorithms. The dataset's simple and well-structured format makes it an essential resource for researchers and practitioners in the field of machine learning and computer vision.
## Usage
To train a CNN model on the MNIST dataset for 100 [epochs](https://www.ultralytics.com/glossary/epoch) with an image size of 32x32, you can use the following code snippets. For a comprehensive list of available arguments, refer to the model [Training](../../modes/train.md) page.
