-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("wmt16", "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()
-```
