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 3 new columns ({'ordre', 'compagnie', 'ligne'}) and 5 missing columns ({'lon', 'lat', 'quartier', 'commune', 'confiance'}).
This happened while the csv dataset builder was generating data using

Dakar Bus Network
Bus lines and ordered stops for Dakar, Senegal: 112 lines (40 Dakar Dem Dikk, 72 Tata AFTU) and about 1,150 ordered stops, with stop and place coordinates.
Pre-existing data. This dataset was compiled by Cheikh Niang before the Meta Global AI Developer Hackathon (Oct 26 to Nov 4, 2026), for the GuindiMa AI project. It is published separately so that new projects (such as Koumba) can load it.
