winogrande cannot be dowloaded 
I have same issue for other datasets (`myanmar_news` in my case).

A version of `datasets` runs correctly on my local machine (**without GPU**) which looking for the dataset at 
```
https://raw.githubusercontent.com/huggingface/datasets/master/datasets/myanmar_news/myanmar_news.py
```

Meanwhile, other version runs on Colab (**with GPU**) failed to download the dataset. It try to find the dataset at `1.1.3` instead of `master` . If I disable GPU on my Colab, the code can load the dataset without any problem.

Maybe there is some version missmatch with the GPU and CPU version of code for these datasets?
Hi,
I am getting this error when trying to run the codes on the cloud.  Thank you for any suggestion and help on this @lhoestq
