Build a custom `Layer` by creating subclasses. Subclasses need to follow the following rules:
1. Subclasses contain `forward` and `backward` function. Both forward and backward are @staticmethod.
Their first argument should be a context and `None` can not be included in the returned result.
2. Input of backward contains a context as the first argument, and the rest arguments are the
gradient of forward's output tensors. so the number of backward's input tensors equal to
the number of forward output tensors. If you need the forward's inputs or outputs in `backward`,
you can use `save_for_backward` to store the required tensors, and then use them in the backward.
3. Output of backward function can only be `Tensor` or tuple/list of `Tensor`.
Output tensors of backward are the gradient of forward's input tensors,
so the number of backward's output tensors equal to the number of forward input tensors.
After building the custom Layer, run it through the `apply` method.
Examples:
.. code-block:: python
import paddle
from paddle.autograd import PyLayer
# Inherit from PyLayer
class cus_tanh(PyLayer):
@staticmethod
def forward(ctx, x, func1, func2=paddle.square):
# ctx is a context object that store some objects for backward.
ctx.func = func2
y = func1(x)
# Pass tensors to backward.
ctx.save_for_backward(y)
return y
@staticmethod
# forward has only one output, so there is only one gradient in the input of backward.
def backward(ctx, dy):
# Get the tensors passed by forward.
y, = ctx.saved_tensor()
grad = dy * (1 - ctx.func(y))
# forward has only one input, so only one gradient tensor is returned.
