一、代码说明
layers是一个计算单元,其输入和输出都是variable
fetch_list获取输入数据
将一个Program()放到Executor中执行运算
from paddle import fluid
x = fluid.layers.fill_constant(shape=[1],dtype='int64',value=5)
y = fluid.layers.fill_constant(shape=[1],dtype='int64',value=1)
z = x+y
exe = fluid.Executor(fluid.CPUPlace())
exe.run(fluid.default_main_program(),fetch_list=[z])
二、执行结果:
