# coco2017
Image-text pairs from [COCO2017](https://cocodataset.org/#download).
## Data origin
* Data originates from [cocodataset.org](http://images.cocodataset.org/annotations/annotations_trainval2017.zip)
* While `coco-karpathy` uses a dense format (with several sentences and sendids per row), `coco-karpathy-long` uses a long format with one `sentence` (aka caption) and `sendid` per row. `coco-karpathy-long` uses the first five sentences and therefore is five times as long as `coco-karpathy`.
* `phiyodr/coco2017`: One row corresponds one image with several sentences.
* `phiyodr/coco2017-long`: One row correspond one sentence (aka caption). There are 5 rows (sometimes more) with the same image details.
## Format
```python
DatasetDict({
train: Dataset({
features: ['license', 'file_name', 'coco_url', 'height', 'width', 'date_captured', 'flickr_url', 'image_id', 'ids', 'captions'],
num_rows: 118287
})
validation: Dataset({
features: ['license', 'file_name', 'coco_url', 'height', 'width', 'date_captured', 'flickr_url', 'image_id', 'ids', 'captions'],
num_rows: 5000
})
})
```
## Usage
* Download image data and unzip
```bash
cd PATH_TO_FOLDER
wget http://images.cocodataset.org/zips/train2017.zip
wget http://images.cocodataset.org/zips/val2017.zip
#wget http://images.cocodataset.org/annotations/annotations_trainval2017.zip # zip not needed: everything you need is in load_dataset("phiyodr/coco2017")
unzip train2017.zip
unzip val2017.zip
```
* Load dataset in Python
```python
import os
from datasets import load_dataset
PATH_TO_IMAGE_FOLDER = "COCO2017"
def create_full_path(example):
"""Create full path to image using `base_path` to COCO2017 folder."""
example["image_path"] = os.path.join(PATH_TO_IMAGE_FOLDER, example["filepath"], example["filename"])
return example
dataset = load_dataset("phiyodr/coco2017")
dataset = dataset.map(create_full_path)
