`Dataset`/`DatasetDict` has no attribute 'save_to_disk'

`pip install git+https://github.com/huggingface/nlp.git` should have done the job.

Did you uninstall `nlp` before installing from github ?

I did not. I created a new environment and installed `nlp` directly from `github` and it worked!

Thanks.

Hi,

As the title indicates, both `Dataset` and `DatasetDict` classes don't seem to have the `save_to_disk` method.  While the file [`arrow_dataset.py`](https://github.com/huggingface/nlp/blob/34bf0b03bfe03e7f77b8fec1cd48f5452c4fc7c1/src/nlp/arrow_dataset.py) in the repo here has the method, the file `arrow_dataset.py` which is saved after `pip install nlp -U` in my `conda` environment DOES NOT contain the `save_to_disk` method. I even tried `pip install git+https://github.com/huggingface/nlp.git ` and still no luck. Do I need to install the library in another way?
