A deep matching model library for recommendations & advertising. It's easy to train models and to export representation vectors which can be used for ANN search.

当我用vocabulary_path的方式做hash，如下： VarLenSparseFeat(SparseFeat('short_item', vocabulary_size=100, embedding_dim=8,use_hash=True,vocabulary_path=index,dtype='int32',embeddings_initializer='uniform', embedding_name='item'), 4,'mean', length_name="short_sess_length")
