name_scope

paddle.static.name_scope ( prefix=None ) [源代码]

该函数为静态图下的operators生成不同的命名空间。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。

参数：

  • prefix (str，可选) - 名称前缀。默认值为None。

示例代码

  1. import paddle
  2. paddle.enable_static()
  3. with paddle.static.name_scope("s1"):
  4.    a = paddle.static.data(name='data', shape=[None, 1], dtype='int32')
  5.    b = a + 1
  6.    with paddle.static.name_scope("s2"):
  7.       c = b * 1
  8.    with paddle.static.name_scope("s3"):
  9.       d = c / 1
  10. with paddle.static.name_scope("s1"):
  11.       f = paddle.tensor.pow(d, 2.0)
  12.       print(f)
  13. with paddle.static.name_scope("s4"):
  14.       g = f - 1
  16. # Op are created in the default main program.
  17. for op in paddle.static.default_main_program().block(0).ops:
  18.     # elementwise_add is created in /s1/
  19.     if op.type == 'elementwise_add':
  20.         assert op.desc.attr("op_namescope") == '/s1/'
  21.     # elementwise_mul is created in '/s1/s2'
  22.     elif op.type == 'elementwise_mul':
  23.         assert op.desc.attr("op_namescope") == '/s1/s2/'
  24.     # elementwise_div is created in '/s1/s3'
  25.     elif op.type == 'elementwise_div':
  26.         assert op.desc.attr("op_namescope") == '/s1/s3/'
  27.     # elementwise_sub is created in '/s4'
  28.     elif op.type == 'elementwise_sub':
  29.         assert op.desc.attr("op_namescope") == '/s4/'
  30.     # pow is created in /s1_1/
  31.     elif op.type == 'pow':
  32.         assert op.desc.attr("op_namescope") == '/s1_1/'
