以下是我做写的一个加法计算，

# coding=utf-8
import paddle.fluid as fluid

# 创建两常量
a = fluid.layers.fill_constant(shape=[2, 3], dtype="float32", value=1.0)
b = fluid.layers.fill_constant(shape=[2, 3], dtype="float32", value=1.0)

# 加法计算
c = fluid.layers.sum(a, b)

# 转换为打印信息
c_ = fluid.layers.Print(c)
print(c_)

最后输出的以下张量的信息，但我需要的是它的值

name: "print_0.tmp_0"
type {
  type: LOD_TENSOR
  lod_tensor {
    tensor {
      data_type: FP32
      dims: 2
      dims: 3
    }
    lod_level: 0
  }
}
persistable: false
