### Dataset Summary

The WMT EnDe Translate dataset used by the Tensor2Tensor library.

Translation dataset based on the data from statmt.org.

Versions exist for different years using a combination of data
sources. The base `wmt` allows you to create a custom dataset by choosing
your own data/language pair. This can be done as follows:

```python
from datasets import inspect_dataset, load_dataset_builder

inspect_dataset("wmt_t2t", "path/to/scripts")
builder = load_dataset_builder(
    "path/to/scripts/wmt_utils.py",
    language_pair=("fr", "de"),
    subsets={
        datasets.Split.TRAIN: ["commoncrawl_frde"],
        datasets.Split.VALIDATION: ["euelections_dev2019"],
    },
)

# Standard version
builder.download_and_prepare()
ds = builder.as_dataset()

# Streamable version
ds = builder.as_streaming_dataset()
```

## Dataset Structure

### Data Instances

#### de-en

- **Size of downloaded dataset files:** 1.73 GB
- **Size of the generated dataset:** 1.39 GB
- **Total amount of disk used:** 3.11 GB

An example of 'validation' looks as follows.
```
{
    "translation": {
        "de": "Just a test sentence.",
        "en": "Just a test sentence."
    }
}
```

### Data Fields

The data fields are the same among all splits.

#### de-en
- `translation`: a multilingual `string` variable, with possible languages including `de`, `en`.

### Data Splits

|name | train |validation|test|
|-----|------:|---------:|---:|
|de-en|4592289|      3000|3003|
