GitHub issue #6917: WinError 32 The process cannot access the file during load_dataset
State: open | Created: 2024-05-24T07:54:51Z

### Describe the bug

When I try to load the opus_book from hugging face (following the [guide on the website](https://huggingface.co/docs/transformers/main/en/tasks/translation))

```python
from datasets import load_dataset, Dataset

dataset = load_dataset("Helsinki-NLP/opus_books", "en-fr", features=["id", "translation"])
```

I get an error:
`PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:/Users/Me/.cache/huggingface/datasets/Helsinki-NLP___parquet/ca-de-a39f1ef185b9b73b/0.0.0/2a3b91fbd88a2c90d1dbbb32b460cf621d31bd5b05b934492fdef7d8d6f236ec.incomplete\\parquet-train-00000-00000-of-NNNNN.arrow'

### Steps to reproduce the bug

Steps to reproduce:

Just execute these lines

```python
from datasets import load_dataset, Dataset

dataset = load_dataset("Helsinki-NLP/opus_books", "en-fr", features=["id", "translation"])
```


### Expected behavior

I expect the dataset to be loaded without any errors.
