Datasetbuilder Local Download FileNotFoundError

[purefall]

Describe the bug

So I was trying to download a dataset and save it as parquet and I follow the tutorial of Huggingface. However, during the excution I face a FileNotFoundError.

I debug the code and it seems there is a bug there:
So first it creates a .incomplete folder and before moving its contents the following code deletes the directory
Code
hence as a result I face with:

FileNotFoundError: [Errno 2] No such file or directory: '~/data/Parquet/.incomplete '

Steps to reproduce the bug

from datasets import load_dataset_builder
from pathlib import Path

parquet_dir = "~/data/Parquet/" 
Path(parquet_dir).mkdir(parents=True, exist_ok=True)
builder = load_dataset_builder(
    "rotten_tomatoes",
)
builder.download_and_prepare(parquet_dir, file_format="parquet")

Expected behavior

Downloads the files and saves as parquet

Environment info

Ubuntu,
Python 3.10

datasets 2.19.1

Ok it seems the solution is to use the directory string without the trailing "/" which in my case as:

parquet_dir = "~/data/Parquet"

Still i think this is a weird behavior...
