CodaLab

Dear Codalab users,

As you know, we recently migrated to a new server codalab.lisn.fr. The old server competitions.codalab.org

From August 31, 2022: no more submission accepted (exceptions may be granted with specific motives until December 2022).

From January 1, 2023: old server is only read-only for good.

Please migrate your competitions to the new server accordingly (see dump feature here in the wiki). Note: submissions on old competitions cannot be migrated.

Thanks for using Codalab!
