 ### 💡 Do you want to try your own input fusion mechanism with BigEarthNetv2.0? 
 The second version of the BigEarthNetv2.0 dataset is stored in `data/bigearthnet/processed/`. These datasets are stored as 3 H5PY datasets (`.h5`) for each split in the dataset. 
 This version of the processed dataset comes with (i) raw location co-ordinates, and (ii) pre-computed SatCLIP embeddings (L=10, ResNet50 image encoder backbone). 
-You may access these embeddings and location metadata with keys `location` and 'satclip_embedding'.
