How to get embedding per node or edge

Hi,

I was trying TransE embedding of Grape, and I am curious how to get embedding of each node or relation as a vector. For example, 
Protein 1 enables Protein 2. In this triple Protein 1 is subject, Protein 2 is object, and enable is a relation. Now how to get the embedding  separately for Protein 1, enables, and Protein 2 using Grape?

Thanks for your time and help.
