name_scope¶
该函数为静态图下的 operators 生成不同的命名空间。
注解
该函数只用于静态图下的调试和可视化,不建议用在其它方面,否则会引起内存泄露。
参数¶
prefix (str,可选) - 名称前缀。默认值为 None。
代码示例¶
import paddle
paddle.enable_static()
with paddle.static.name_scope("s1"):
a = paddle.static.data(name='data', shape=[None, 1], dtype='int32')
b = a + 1
with paddle.static.name_scope("s2"):
c = b * 1
with paddle.static.name_scope("s3"):
d = c / 1
with paddle.static.name_scope("s1"):
f = paddle.tensor.pow(d, 2.0)
with paddle.static.name_scope("s4"):
g = f - 1
# Op are created in the default main program.

# elementwise_add is created in /s1/
