This operation is used as a tag to hook gradient in intermediate variables. Note that this function
is only supported in pynative mode.
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): 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.
The default value of cell_id is empty string(""), 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:
- **output** (Tensor) - Returns `input` directly. `HookBackward` does not affect the forward result.

TypeError: If `input` is not a tensor.

Outputs the tensor or string to stdout. The outputs are printed to screen by default.
It can also be saved in a file by setting the parameter `print_file_path` in `context`.
Once set, the output will be saved in the file specified by print_file_path.
parse_print can be employed to reload the data.
For more information, please refer to :func:`mindspore.context.set_context` and :func:`mindspore.parse_print`.
Note:
In pynative mode, please use python print function.
In graph mode, the bool, int and float would be converted into Tensor to print,
str remains unchanged.
This function is used for debugging. When too much data is printed at the same time,
in order not to affect the main process, the framework may discard some data. At this time,
if you need to record the data completely, you can recommended to use the `Summary` function. Please check
