+    r"""
+
+    Extracts a strided slice of a tensor.
+
+    Given an input tensor, this operation inserts a dimension of length 1 at the dimension.
+    This operation extracts a fragment of size (end-begin)/stride from the given
+    'input_tensor'. Starting from the position specified by the begin, the fragment
+    continues adding stride to the index until all dimensions are not less than end.
+
+    Note:
+        The stride may be negative value, which causes reverse slicing.
+        The shape of `begin`, `end` and `strides` should be the same.
+
+    Args:
+        begin_mask (int): Starting index of the slice. Default: 0.
+        end_mask (int): Ending index of the slice. Default: 0.
+        ellipsis_mask (int): An int mask. Default: 0.
+        new_axis_mask (int): An int mask. Default: 0.
+        shrink_axis_mask (int): An int mask. Default: 0.
+        Currently all the masks are not in used. Use default 0 only.
+
+    Inputs:
+        - **input_x** (Tensor) - The input Tensor.
+        - **begin** (tuple[int]) - A tuple which represents the location where to start. Only
+          constant value is allowed.
+        - **end** (tuple[int]) - A tuple or which represents the maximum location where to stop.
+          Only constant value is allowed.
+        - **strides** (tuple[int]) - A tuple which represents the stride continuously added
+          before reach the maximum location. Only constant value is allowed.
+
+    Outputs:
+        Tensor.
+        Explain with the following example.
+            - In the 0th dim, begin is 1, end is 2, and strides is 1,
+              because :math:`1+1=2\geq2`, the interval is :math:`[1,2)`.
+              Thus, return the element with :math:`index = 1` in 0th dim, i.e., [[3, 3, 3], [4, 4, 4]].
+            - In the 1st dim, similarly, the interval is :math:`[0,1)`.
+              Based on the return value of the 0th dim, return the element with :math:`index = 0`,
+              i.e., [3, 3, 3].
+            - In the 2nd dim, similarly, the interval is :math:`[0,3)`.
+              Based on the return value of the 1st dim, return the element with :math:`index = 0,1,2`,
+              i.e., [3, 3, 3].
+            - Finally, the output is [3, 3, 3].
+
+    Examples
+        >>> input_x = Tensor([[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]],
+        >>>                   [[5, 5, 5], [6, 6, 6]]], mindspore.float32)
+        >>> slice = P.StridedSliceAICPU()
