同样的也可以使用 ``register_forward_pre_hook()`` 来注册**pre_hook**：

```python
def forward_pre_hook(layer, input, output):
return 2*output
def forward_pre_hook(layer, input):
print(input)
return input

x = paddle.ones([10, 1], 'float32')
model = Model()

Similarly, we can also register a **pre_hook** through ``register_forward_pre_hook()``

```python
def forward_pre_hook(layer, input, output):
return 2*output
def forward_pre_hook(layer, input):
print(input)
