# Dataset Card for "MNIST"

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

>>> dataset = load_dataset('whyen-wang/mnist')
>>> example = dataset['train'][0]
>>> print(example)
{'image': <PIL.PngImagePlugin.PngImageFile image mode=L size=28x28>,
 'label': 5}
```

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

>>> def visualize(example):
    image = np.array(example['image'])
    image = cv2.resize(image, (280, 280))
    cv2.putText(
        image, str(example['label']), (0, 50), cv2.FONT_HERSHEY_SIMPLEX,
        2, (255), 1, cv2.LINE_AA, False
    )
    return image

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

### Dataset Summary

The MNIST database of handwritten digits, available from this page, has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST. The digits have been size-normalized and centered in a fixed-size image.

### Supported Tasks and Leaderboards

## Dataset Structure

### Data Instances

An example looks as follows.

```
