paddle.fluid / layers / ones
ones¶
该OP创建形状为 shape 、数据类型为 dtype 且值全为1的Tensor。
- 参数：
-
shape (tuple|list|Tensor) - 输出Tensor的形状，
shape的数据类型为int32或者int64。dtype (np.dtype|str) - 输出Tensor的数据类型，数据类型必须为bool、 float16、float32、float64、int32或int64。
force_cpu (bool， 可选) – 是否强制将输出Tensor写入CPU内存。如果
force_cpu为False，则将输出Tensor写入当前所在运算设备的内存，默认为False。
返回：值全为1的Tensor，数据类型和 dtype 定义的类型一致。
代码示例：
import paddle.fluid as fluid
data = fluid.layers.ones(shape=[2, 4], dtype='float32') # [[1., 1., 1., 1.], [1., 1., 1., 1.]]
