Thanks! What are the licenses of these datasets? Could you add them to the classes?
If the dataset licenses are friendly, we can consider redistributing them.

OK, I can add the license for LCQMC and XNLI.
LCQMC is licensed under a Creative Commons Attribution 4.0 International License. License details: http://creativecommons.org/licenses/by/4.0/. XNLI has Attribution-NonCommercial 4.0 International
license : https://github.com/facebookresearch/XNLI/blob/master/LICENSE, (https://creativecommons.org/licenses/by-nc/4.0/). But I can't find ChnSentiCorp's license. All these dataset are redistributed by baidu. Seems we can at least redistribute XNLI and LCQMC.

We probably can't redistribute XNLI due to the non-commercial license.

It only means that we cannot host the dataset, right? Using external links is fine?

[eric-haibin-lin]

could you fix the lint failure ?
