Currently, Paddle distinguishes the names of the same key by numbering it from zero. For example, when key=fc, it continuously generates fc_0, fc_1, fc_2, etc. Args: key(str): The prefix of generated name. Returns: str: A unique string with the prefix key. Examples: .. code-block:: python >>> import paddle >>> name1 = paddle.utils.unique_name.generate('fc') >>> name2 = paddle.utils.unique_name.generate('fc') >>> print(name1, name2) fc_0 fc_1 ) generator)rs rgenerater*Qs, S>rc`ddlm}m}|r|jSt |S)Nr)_dygraph_tracerin_dygraph_mode) frameworkr,r-_generate_unique_namer))rr,r-s rgenerate_with_ignorable_keyr0|s'; 6688 S>rcdt}t}| tan|a|ta||fS|a||fS)a/ Switch the namespace of in current context to a new namespace. Though :code:`switch()` and :code:`guard()` can both change namespace, :code:`guard()` is recommended since it can manage the context better together with :code:`with` statement. Args: new_generator(UniqueNameGenerator, optional): A new UniqueNameGenerator, not required normally. Default is None, which means switch to a new anonymous namespace. new_para_name_checker(DygraphParameterNameChecker, optional): A new DygraphParameterNameChecker, not required normally. Default is None, which means switch to a new parameter name checker. Returns: UniqueNameGenerator: The previous UniqueNameGenerator. DygraphParameterNameChecker: The previous DygraphParameterNameChecker Examples: .. code-block:: python >>> import paddle >>> name1 = paddle.utils.unique_name.generate('fc') >>> name2 = paddle.utils.unique_name.generate('fc') >>> print(name1, name2) fc_0 fc_1 >>> pre_generator, pre_dygraph_name_checker = paddle.utils.unique_name.switch() # switch to a new anonymous namespace. >>> name2 = paddle.utils.unique_name.generate('fc') >>> print(name2) fc_0 >>> paddle.utils.unique_name.switch(pre_generator, pre_dygraph_name_checker) # switch back to pre_generator. >>> name3 = paddle.utils.unique_name.generate('fc') >>> print(name3) fc_2 )r)dygraph_parameter_name_checkerrr!) new_generatornew_para_name_checker old_generatorold_para_name_checkers rswitchr7sTPM:') ! $)D)F& / //*?& / //rc#Kt|tr t|}n)t|trt|j }t |\}} dt ||y#t ||wxYww)a% Change the namespace of unique name with :code:`with` statement. After calling it, a new namespace in the context of :code:`with` will be created, and it will number names from zero again when calling :code:`generate()` with same key. Args: 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 :code:`generate()`. Returns: None. Examples: .. code-block:: python >>> 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 N) isinstancerrbytesdecoder7)r3r5r6s rguardr<shF-%+M: M5 )+M,@,@,BC +1-+@(M(5 }34}34sAA9A( A9(A66A9)NNr) r wrapped_decoratorr__all__rr!r2r)r*r0r7r<rrrr?s^< 77:2"=!>  !
