name_scope
该函数为静态图下的 operators 生成不同的命名空间。
备注
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.pir_utils.OldIrGuard():
... with paddle.static.name_scope("s1"):
... a = paddle.static.data(name='data', shape=[None, 1], dtype='int32')
... b = a + paddle.to_tensor(1)
... with paddle.static.name_scope("s2"):
... c = b * paddle.to_tensor(1)
... with paddle.static.name_scope("s3"):
... d = c / paddle.to_tensor(1)
... with paddle.static.name_scope("s1"):
... f = paddle.tensor.pow(d, paddle.to_tensor(2.0))
... with paddle.static.name_scope("s4"):
... g = f - paddle.to_tensor(1)
