COCO 🥥 on the 🤗 Hub?
@mariosasko I fixed couple of bugs TO-DO: 
- [x] Add unlabeled 2017 splits, train and validation splits of 2015
- [x] Add Class Labels as list instead @mariosasko added fine & coarse grained labels, will fix the bugs (currently getting set up with VM, my internet is too slow to run the tests and download the data 🥲) migrated to here https://github.com/huggingface/datasets/tree/coco
This is a draft PR since I ran into few small problems. 
I referred to this TFDS code: https://github.com/tensorflow/datasets/blob/2538a08c184d53b37bfcf52cc21dd382572a88f4/tensorflow_datasets/object_detection/coco.py
