Add the ADE20K dataset in TorchVision

[datumbox]

🚀 The feature

ADE20K is a dataset introduced in 2017 for Object Detection and Segmentation (code here). It has 371 citations and it's become more and more popular as a benchmark.

We should consider adding it to TorchVision using the new Dataset API.

This might be a good onboarding task for the new datasets.

I'll do it

Is there a need for any support on this?

[pmeier]

@23pointsNorth We are currently halting further contributions to the prototype datasets, since there are some details that need to be figured out. If that is resolved, I'm guessing @NicolasHug can assign it to you given that he already did quite a few ports and no longer needs to be on-boarded.

Hi @datumbox, @pmeier! Are you planning to resume the process of adding ADE20K?

[kswain98]

Hi! I was just wondering if I can add ADE20k support here?

[NicolasHug]

Hi @kswain55 , sorry for the slow reply. We're not really prioritizing the addition of more datasets at this time. Do you think getting this dataset from e.g. the HuggingFace hub would suit you?
