Loading partial dataset when debugging
Hi @reachtarunhere.

Besides the above insights provided by @lhoestq and @thomwolf, there is also a Dataset feature in progress (I plan to finish it this week): #2249, which will allow you, when calling `load_dataset`, to pass the option to download/preprocess/cache only some specific split(s), which will definitely speed up your workflow.

If this feature is interesting for you, I can ping you once it will be merged into the master branch.
I am using PyTorch Lightning along with datasets (thanks for so many datasets already prepared and the great splits). 

Every time I execute load_dataset  for the imdb dataset it takes some time even if I specify a split involving very few samples. I guess this due to hashing as per the other issues.

Is there a way to only load part of the dataset on load_dataset? This would really speed up my workflow.
Something like a debug mode would really help. Thanks!
