Constant¶

class paddle.nn.initializer. Constant ( value=0.0 ) [源代码] ¶

该接口为常量初始化函数，用于权重初始化，通过输入的value值初始化输入变量；

参数：

• value (float16|float32) - 用于初始化输入变量的值；

返回：参数初始化类的实例

代码示例

import paddle
import paddle.nn as nn

data = paddle.rand([30, 10, 2], dtype='float32')
linear = nn.Linear(2, 4, weight_attr=nn.initializer.Constant(value=2.0))
res = linear(data)
print(linear.weight.numpy())
#result is [[2. 2. 2. 2.],[2. 2. 2. 2.]]
