Trouble loading wiki_movies
Hi ! `wiki_movies` was added in `datasets==1.2.0`. However it looks like you have `datasets==1.1.2`.

To use `wiki_movies`, please update `datasets` with
```
pip install --upgrade datasets
``` Thanks a lot! That solved it and I was able to upload a model trained on it as well :)
Hello,
I am trying to load_dataset("wiki_movies") and it gives me this error - 

`FileNotFoundError: Couldn't find file locally at wiki_movies/wiki_movies.py, or remotely at https://raw.githubusercontent.com/huggingface/datasets/1.1.2/datasets/wiki_movies/wiki_movies.py or https://s3.amazonaws.com/datasets.huggingface.co/datasets/datasets/wiki_movies/wiki_movies.py`

Trying to do `python run_mlm.py \
    --model_name_or_path roberta-base \
    --dataset_name wiki_movies \` also gives the same error. 

Is this something on my end? From what I can tell, this dataset was re-added by @lhoestq a few months ago. 
Thank you!
