How to use Dynamic-dimension Embedding Variable?

[fuhailin]

Refer to the document of Dynamic-dim Embedding Variable, I got that 当使用dynamic dimension embedding variable的时候，在embedding_lookup的时候需要传入blocknum上参数，用来指示每一个特征对应的blocknum.

But I am confused about how to assign blocknum for every feature when embedding lookup. Could you please provide a minimal example to show how to initialize and look_up Dynamic-dimension Embedding Variable?
