Scifi_TV_Shows: Having trouble getting viewer to find appropriate files
Hi ! I think this is because `iter_archive` doesn't support ZIP files yet. See https://github.com/huggingface/datasets/issues/3272

You can navigate into the archive this way instead:
```python
# in split_generators
data_dir = dl_manager.download_and_extract(url)
train_filepath = os.path.join(data_dir, "all-sci-fi-data-train.txt")
return [
        datasets.SplitGenerator(
            name=datasets.Split.TRAIN,
            gen_kwargs={
                "filepath": train_filepath,
            },
        ),
...
])

# in generate_examples
with open(filepath, encoding="utf-8") as f:
    ...
``` It's working: https://huggingface.co/datasets/lara-martin/Scifi_TV_Shows/viewer/Scifi_TV_Shows/test

## Dataset viewer issue for '*Science Fiction TV Show Plots Corpus  (Scifi_TV_Shows)*'

**Link:** [link](https://huggingface.co/datasets/lara-martin/Scifi_TV_Shows)

I tried adding both a script (https://huggingface.co/datasets/lara-martin/Scifi_TV_Shows/blob/main/Scifi_TV_Shows.py) and some dummy examples (https://huggingface.co/datasets/lara-martin/Scifi_TV_Shows/tree/main/dummy), but the viewer still has a 404 error ("Not found. Maybe the cache is missing, or maybe the ressource does not exist."). I'm not sure what to try next. Thanks in advance!

Am I the one who added this dataset? Yes
