@sywangyi Could you try with the latest release of Datasets (v2.19.2) please? It should solve this issue, i.e. no need for verification_mode="no_checks" anymore.

[sywangyi]

yes. works in 2.19.2

Great! Could you remove verification_mode="no_checks" from the examples (dpo.py too) and set the requirements datasets==2.19.2 in requirements.txt please?

[sywangyi]

ok, I will do it
