[3rd party license header] reuse sklearn example?

Hi guys,

I wonder what license header should I use if I want to modify a sklearn example? This is an example code with a BSD 3-Clause header.



I would suggest using Apache License which is compatible with DGL, and including the author information in the header to comply with BSD 3 license.

Thanks. FYI, here is the pull request: [Example] add latent dirichlet allocation by yifeim · Pull Request #2883 · dmlc/dgl · GitHub
