Cannot download ade_corpus_v2
Hi @him1411, the dataset you are trying to load has been added during the community sprint and has not been released yet. It will be available with the v2 of `datasets`.
For now, you should be able to load the datasets after installing the latest (master) version of `datasets` using pip:
`pip install git+https://github.com/huggingface/datasets.git@master`
I tried this to get the dataset following this url : https://huggingface.co/datasets/ade_corpus_v2

but received this error :
