     Args:
 
         input (Variable): a 2-D LodTensor with shape [N x D], where N is the batch size, D is 2 + the embedding dim. lod level = 1.
         cvm (Variable):   a 2-D Tensor with shape [N x 2], where N is the batch size, 2 is show and click.
         use_cvm  (bool):  use cvm or not. if use cvm, the output dim is the same as input
-                          if don't use cvm, the output dim is input dim - 2(remove show and click).
-                          (cvm op is a customized op, which input is a sequence had embedd_with_cvm default, so we need a op named cvm to decided whever use it or not.)
