guard¶

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

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