Issue: [BUG] With Pandas 2.0.0, `load_dataset` raises `TypeError: read_csv() got an unexpected keyword argument 'mangle_dupe_cols'`
State: closed
Author: keyboardAnt

The `load_dataset` function with Pandas `1.5.3` has no issue (just a FutureWarning) but crashes with Pandas `2.0.0`.
For your convenience, I opened a draft Pull Request to fix it quickly: https://github.com/huggingface/datasets/pull/5745

---

* The FutureWarning mentioned above: 
```
FutureWarning: the 'mangle_dupe_cols' keyword is deprecated and will be removed in a future version. Please take steps to stop the use of 'mangle_dupe_cols'
```

Comments:
Thanks for reporting, @keyboardAnt.

We haven't noticed any crash in our CI tests. Could you please indicate specifically the `load_dataset` command that crashes in your side, so that we can reproduce it?

This has been fixed in `datasets` 2.11

I am still getting this bug with the latest pandas and datasets lib installed. Anyone else?
```
from datasets import load_dataset

dataset = load_dataset("csv", data_files={"train":"/kaggle/working/train.csv", "test":"/kaggle/working/test.csv"})
print(dataset)

Feel free to update `datasets` to fix this issue

```
pip install -U datasets
```

I am still having the same issue with the version >= 2.14
