# Dataset Card for "COCO Captions"

## Quick Start
### Usage
```python
>>> from datasets.load import load_dataset

>>> dataset = load_dataset('whyen-wang/coco_captions')
>>> example = dataset['train'][500]
>>> print(example)
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=640x426>,
 'captions': ['A plate that has food on top of it with powdered sugar.',
  'A breakfast item on a plate is sitting on a table.',
  'different kinds of food on a glass plate',
  'a bowl with some pancakes and toppings on it',
  'Pancakes on a plate with banana, sauce and whipped cream toppings']}
```

### Visualization
```python
>>> import cv2
>>> import numpy as np
>>> from PIL import Image

>>> def visualize(example):
    for caption in example['captions']:
        print(caption)
    image = np.array(example['image'])
    return image

>>> Image.fromarray(example)
```
