Constant¶
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.]]
