Sequential¶
顺序容器。子 Layer 将按构造函数参数的顺序添加到此容器中。传递给构造函数的参数可以 Layers 或可迭代的 name Layer 元组。
参数¶
layers (tuple) - Layers 或可迭代的 name Layer 对。
返回¶
无
代码示例¶
import paddle
import numpy as np
data = np.random.uniform(-1, 1, [30, 10]).astype('float32')
data = paddle.to_tensor(data)
# create Sequential with iterable Layers
model1 = paddle.nn.Sequential(
paddle.nn.Linear(10, 1), paddle.nn.Linear(1, 2)
)
model1[0] # access the first layer
res1 = model1(data) # sequential execution
# create Sequential with name Layer pairs
model2 = paddle.nn.Sequential(
('l1', paddle.nn.Linear(10, 2)),
('l2', paddle.nn.Linear(2, 3))
)
model2['l1'] # access l1 layer
model2.add_sublayer('l3', paddle.nn.Linear(3, 3)) # add sublayer
res2 = model2(data) # sequential execution
