Case 1:
::
Input:
Input. Shape = [2, 3]
Input = [[1, 2, 3],
[4, 5, 6]]

Output:
The output. Shape = [2, 3]
Output = [[1, 2, 3],

Case 2:
::
Input:
First input:
Input1. Shape = [2, 3]
Input1 = [[1, 2, 3],
[4, 5, 6]]

The second input:
Input2. Shape = [2, 3]
Input2 = [[7, 8, 9],
[10, 11, 12]]

Output:
The output. Shape = [2, 3]
Output = [[8, 10, 12],

This OP is used to sum one or more Tensor of the input.

For example:

.. code-block:: text

Case 1:

Input:
input.shape = [2, 3]
input = [[1, 2, 3],
[4, 5, 6]]

Output:
output.shape = [2, 3]
output = [[1, 2, 3],
[4, 5, 6]]

Case 2:

Input:
First input:
input1.shape = [2, 3]
Input1 = [[1, 2, 3],
[4, 5, 6]]

The second input:
input2.shape = [2, 3]
input2 = [[7, 8, 9],
[10, 11, 12]]

Output:
output.shape = [2, 3]
output = [[8, 10, 12],
[14, 16, 18]]

Args:
inputs (Tensor|list(Tensor)): A Tensor list. The shape and data type of the list elements should be consistent.
