	### Dataset Summary

	<div class="course-tip course-tip-orange bg-gradient-to-br dark:bg-gradient-to-r before:border-orange-500 dark:before:border-orange-800 from-orange-50 dark:from-gray-900 to-white dark:to-gray-950 border border-orange-50 text-orange-700 dark:text-gray-400">
	<p><b>Warning:</b> There are issues with the Common Crawl corpus data (<a href="https://www.statmt.org/wmt13/training-parallel-commoncrawl.tgz">training-parallel-commoncrawl.tgz</a>):</p>
	<ul>
	<li>Non-English files contain many English sentences.</li>
	<li>Their "parallel" sentences in English are not aligned: they are uncorrelated with their counterpart.</li>
	</ul>
	<p>We have contacted the WMT organizers, and in response, they have indicated that they do not have plans to update the Common Crawl corpus data. Their rationale pertains to the expectation that such data has been superseded, primarily by CCMatrix, and to some extent, by ParaCrawl datasets.</p>
	</div>

	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("wmt19", "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

	#### cs-en

	- Size of downloaded dataset files: 2.02 GB
	- Size of the generated dataset: 1.32 GB
	- Total amount of disk used: 3.33 GB

	An example of 'validation' looks as follows.
	```

	```

	### Data Fields

	The data fields are the same among all splits.

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