I/O error on Google Colab in streaming mode

## Describe the bug
When trying to load a streaming dataset in Google Colab the loading fails with an I/O error

## Steps to reproduce the bug
```python
import datasets
from datasets import load_dataset
hf_ds = load_dataset(path='wmt19', name='cs-en', streaming=True, split=datasets.Split.VALIDATION)
list(hf_ds.take(5))
```

## Expected results
It should load five data points

## Actual results
```
