Add an Open Source License

Have you considered adding an open source license to this Git repository?
I created a set of test datasets using code from this git repository, but am not sure if I can upload them to huggingface.

I have supplemented an open-source license to the Git repository.
Of course, you can upload your code to huggingface.
