The dataset is sadly not really compatible to be loaded with `load_dataset`. So far it is better to git clone it and to use the files directly.

A data loading script would be needed to be added to this dataset. But this was too much overhead / not really intuitive how to create it.

Since the dataset is a bunch of TSVs we should not need a dataset script I think.

By default it tries to load all the TSVs at once, which fails here because they don't all have the same columns (pd.read_csv uses the first line as header by default). But those files have no header ! So, to properly load any TSV file in this repo, one has to pass `names=[...]` for pd.read_csv to know which column names to use.

To fix this situation, we can either do
1. replace the TSVs by TSV with column names
2. OR specify the pd.read_csv kwargs as YAML in the dataset card - and `datasets` would use that by default

WDTY ?

There are more issues in the dataset.
To load OpenSubtitles I have to provide this (see `skiprows`):

```python
df_os = pd.read_csv(
    "./parallel-sentences/OpenSubtitles/OpenSubtitles-en-de-train.tsv.gz", 
    sep="\t", 
    quoting=csv.QUOTE_NONE,
    header=None,
    names=["en", "de"],
    skiprows=[540344, 9151700, 10040173, 10040199, 11314673, 11338258, 11869223, 12159297, 12251078, 12303334],
)
```

What's wrong with those lines exactly ?
Maybe passing `error_bad_lines=False` (and maybe `warn_bad_lines=True`) can be helpful

> What's wrong with those lines exactly ? 

Stuff like this: `ParserError: Error tokenizing data. C error: Expected 2 fields in line 540345, saw 3`



>  Maybe passing error_bad_lines=False (and maybe warn_bad_lines=True) can be helpful

Yes. That would hide the issue but not solve it.

@nreimers WDYT about the two options mentioned above ?
