Citations missing #605
Description
Hello! I noticed that the citations are missing on this page: https://github.com/deepmodeling/deepmd-kit/blob/master/doc/use-deepmd-kit.md#train-a-model . The page has "[2]" and "[3]", but not the actual papers to which it refers. Upon searching, I believe these refer to https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.120.143001 and https://papers.nips.cc/paper/2018/hash/e2ad76f2326fbc6b56a45a56c59fafdb-Abstract.html (or https://arxiv.org/abs/1805.09003 ), is this correct? Thank you!
