The link in the line "You will need an API key. RF100 can be accessed with any key from Roboflow, head over our doc to learn how to get one." is incorrectly quoted and does not work.
When downloading the data, a request to read the terms of service pops up. The terms of service explicitly disallow downloading https://roboflow.com/terms (section 3).
The download script at https://github.com/roboflow/roboflow-100-benchmark/blob/main... got stuck at "Generating version still in progress. Progress: 98.75%". When restarting the script, it got stuck at "Generating version still in progress. Progress: 148.15%".
The websites for the individual classes (e.g. https://universe.roboflow.com/roboflow-100/solar-panels-taxv... ) state that the data is licensed under "CC BY 4.0", but what are the exact attribution instructions? There is some BibTeX which should be cited if the data is used in a research paper, but what about other cases?
