# COCO8-Pose Dataset
|
|
|
|
## Introduction
|
|
|
|
[Ultralytics](https://ultralytics.com) COCO8-Pose is a small, but versatile pose detection dataset composed of the first
|
|
8 images of the COCO train 2017 set, 4 for training and 4 for validation. This dataset is ideal for testing and
|
|
debugging object detection models, or for experimenting with new detection approaches. With 8 images, it is small enough
|
|
to be easily manageable, yet diverse enough to test training pipelines for errors and act as a sanity check before
|
|
training larger datasets.
|
|
|
|
This dataset is intended for use with Ultralytics [HUB](https://hub.ultralytics.com)
|
|
and [YOLOv8](https://github.com/ultralytics/ultralytics).
|
|
|
|
## Dataset YAML
|
|
|
|
A YAML (Yet Another Markup Language) file is used to define the dataset configuration. It contains information about the dataset's paths, classes, and other relevant information. In the case of the COCO8-Pose dataset, the `coco8-pose.yaml` file is maintained at [https://github.com/ultralytics/ultralytics/blob/main/ultralytics/datasets/coco8-pose.yaml](https://github.com/ultralytics/ultralytics/blob/main/ultralytics/datasets/coco8-pose.yaml).

```

## Usage
|
|
|
|
To train a YOLOv8n model on the COCO8-Pose dataset for 100 epochs with an image size of 640, 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('yolov8n.pt') # load a pretrained model (recommended for training)
|
|
|
|
# Train the model
|
|
model.train(data='coco8-pose.yaml', epochs=100, imgsz=640)
|
|
```
|
|
|
|
=== "CLI"
|
|
|
|
```bash
|
|
# Start training from a pretrained *.pt model
|
|
yolo detect train data=coco8-pose.yaml model=yolov8n.pt epochs=100 imgsz=640
|
|
```

## Sample Images and Annotations
|
|
|
|
Here are some examples of images from the COCO8-Pose dataset, along with their corresponding annotations:

|

|
|
- **Mosaiced Image**: This image demonstrates a training batch composed of mosaiced dataset images. Mosaicing is a technique used during training that combines multiple images into a single image to increase the variety of objects and scenes within each training batch. This helps improve the model's ability to generalize to different object sizes, aspect ratios, and contexts.
|
|
|
|
The example showcases the variety and complexity of the images in the COCO8-Pose dataset and the benefits of using mosaicing during the training process.
