R"DOC(
Sequence Erase Operator.
Sequence erase operator erases tokens specified by Attr(tokens) in the input
sequences Input(X), and outputs the remaining data and modifies the LoD
information at the same time. For example, given a 2-D LoDTensor
X = [[2, 2, 6, 1, 3, 9, 6, 1, 0, 1]]^T
with lod = [[0, 3, 6, 10]], there are three sequences in the input:
X1 = [[2, 2, 6]]^T, X2 = [[1, 3, 9]]^T and X3 = [[6, 1, 0, 1]]^T.
If the tokens to be erased are Attr(tokens) = [2, 3, 5], after the erasing
operation, the three sequences become
X1' = [[6]]^T, X2' = [[1, 9]]^T and X3' = [[6, 1, 0, 1]]^T.
Hence the LoDTensor Output(Out) should be
Out = [[6, 1, 9, 6, 1, 0, 1]]^T,
with lod = [[0, 1, 3, 7]].
An example usage for this operator is to remove the special tokens when
computing the edit distance between two strings, such as blank, start token,
and end token.
