guard¶

paddle.fluid.unique_name.guard(new_generator=None)[source]

Change the namespace of unique name with with statement. After calling it, a new namespace in the context of with will be created, and it will number names from zero again when calling generate() with same key.

Parameters

new_generator (str|bytes, optional) – New name of global namespace. Note that str in Python2 was spilted into str and bytes in Python3, so here are two types. Default is None. If not None, new_generator will be added into the prefix of unique name generated by generate().

Returns

None.

Examples

import paddle.fluid as fluid
with fluid.unique_name.guard():
  name_1 = fluid.unique_name.generate('fc')
with fluid.unique_name.guard():
  name_2 = fluid.unique_name.generate('fc')
print(name_1, name_2) # fc_0, fc_0

with fluid.unique_name.guard('A'):
  name_1 = fluid.unique_name.generate('fc')
with fluid.unique_name.guard('B'):
  name_2 = fluid.unique_name.generate('fc')
print(name_1, name_2) # Afc_0, Bfc_0
