Error while following docs to load the `ted_talks_iwslt` dataset
@skyprince999 as you authored the PR for this dataset, any comments? This has been fixed in #2064  by @mariosasko (thanks again !)

The fix is available on the master branch and we'll do a new release very soon :)
I am currently trying to load the `ted_talks_iwslt` dataset into google colab.

The [docs](https://huggingface.co/datasets/ted_talks_iwslt) mention the following way of doing so.

```python
dataset = load_dataset("ted_talks_iwslt", language_pair=("it", "pl"), year="2014")
```

Executing it results in the error attached below.

```

How to resolve this? 

PS: Thanks a lot @huggingface team for creating this great library!
