Consider slicing the data to reduce the data scale.

This operation is used as a tag to hook gradient in intermediate variables. Note that this function

Note:
The hook function must be defined like `hook_fn(grad) -> new gradient or None`, where the 'grad' is the
gradient passed to the primitive. The 'grad' may be modified by returning a new gradient and passed to next
primitive. The difference between a hook function and callback of InsertGradientOf is that the hook function is
executed in the python environment while callback will be parsed and added to the graph.
Args:
hook_fn (Function): Python function. hook function.
cell_id (str, optional): Used to identify whether the function registered by the hook is actually registered on
the specified cell object. For example, 'nn.Conv2d' is a cell object.
Default: ``""``, in this case, the system will automatically
register a value of `cell_id`.
The value of `cell_id` currently does not support custom values.
Inputs:
- **input** (Tensor) - The variable to hook.
Outputs:
