Hi guys,
After I downloaded data I found out there is a test set.
Could bring some light what is it and am I supposed to see it and use it?
Regards,
Roman

The `crunch-cli` needs it to be able to validate your scores locally. The `moon` or `dataset_id` (depending on the competition) given in the `y_test` will not be included in the scoring.
