The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError
Exception: DatasetGenerationCastError
Message: An error occurred while generating the dataset
All the data files must have the same columns, but at some point there are 4 new columns ({'num_samples', 'attributes', 'split', 'Dataset'}) and 3 missing columns ({'chunks', 'config', 'updated_at'}).
This happened while the json dataset builder was generating data using
hf://datasets/earthflow/EarthNets_GAMUS/EarthNets_GAMUS/gamus_dataset_train/metadata.json (at revision 8beb82f04fc41cc24215979f9aad56fb2e4c2355)
Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

How to use it
Install Dataset4EO
git clone --branch streaming https://github.com/EarthNets/Dataset4EO.git
pip install -e .
Then download the dataset from this Huggingface repo.
import dataset4eo as eodata
import time
train_dataset = eodata.StreamingDataset(input_dir="EarthNets_GAMUS/EarthNets_GAMUS/optimized_gamus_train", num_channels=3, shuffle=True, drop_last=True)
sample = dataset[101]
print(sample.keys())
print(sample["image"])
print(sample["simage"].shape)
print(sample["label"])
