Hi, I was examining the class GigaPoseTrainSet that implements the data loader. When loading the datasets for training, what it downloads is key_to_shard.json and the various shards. What do the values in key_to_shard.json represent? Thank you in adavanced !

nv-nguyen commented 8 months ago

All the datasets used in GigaPose are taken from BOP challenge 2023.

key_to_shard.json represents the mapping from image_key to shard_id which is mentioned here.
