FAILED tests/test_datasets.py::TestSen1Floods11NonGeo::test_dataset_sample - KeyError: 'location'

[romeokienzler]

Describe the issue
when running tests on main we get
FAILED tests/test_datasets.py::TestSen1Floods11NonGeo::test_dataset_sample - KeyError: 'location'

[Joao-L-S-Almeida]

I updated the branch to the most recent commit (ea44763), defined PYTHONPATH and ran pytest -s tests/test_datasets.py, but I couldn't replicate the issue.

still getting it (Python 3.12.7):

FAILED tests/test_datasets.py::TestSen1Floods11NonGeo::test_dataset_sample - KeyError: 'location'

this is what I did:

git clone [email protected]:IBM/terratorch.git
cd terratorch
git checkout 9a00845
python -m venv .venv
source ./.venv/bin/activate
pip install -U .
pytest
