@ArthurZucker Hi, I have rebased our branch and solved all the conflicts. I think the codes are ready to be merged now.

> Hi @bozheng-hit, recommend using [eval.ai](https://eval.ai/web/challenges/challenge-page/1697/leaderboard) for official test results. We will be opening submissions to the MMNLU-22 phases soon. Is it possible to return results for all languages separately?
