maybe simplify the examples a bit, something like this should suffice
x = paddle.ones(shape=[1], dtype='float32')
x.stop_gradient = False
y = x * x
dx = paddle.grad(
outputs=[y],
inputs=[x],
create_graph=create_graph,
retain_graph=True)[0]
print(dx)
# value should be ....
Thanks for your advice. These example codes here are usefully, better left unchanged. |

感谢。为了展示参数不同时不同的调用效果（代码复用），所以在example代码中定义了函数。
| THREE = fluid.layers.fill_constant(shape=[1], value=3.0, dtype='float32') | ||
| FOUR = fluid.layers.fill_constant(shape=[1], value=4.0, dtype='float32') | ||
| THREE = paddle.fill_constant(shape=[1], value=3.0, dtype='float32') | ||
| FOUR = paddle.fill_constant(shape=[1], value=4.0, dtype='float32') | ||
