Exporting a function or a class: To export a function or a class use tf_export decorator. For e.g.: ```python @tf_export('foo', 'bar.foo') def foo(...): ... ``` If a function is assigned to a variable, you can export it by calling tf_export explicitly. For e.g.: ```python foo = get_foo(...) tf_export('foo', 'bar.foo')(foo) ``` Exporting a constant ```python foo = 1 tf_export('consts.foo').export_constant(__name__, 'foo') ``` N) tf_decorator) tf_inspect estimatorkeras tensorflowZExportedApiAttributesnames constantsZ _tf_api_namesZ_tf_api_constantsZ_estimator_api_namesZ_estimator_api_constantsZ_keras_api_namesZ_keras_api_constantsZ_tf_api_names_v1Z_tf_api_constants_v1Z_estimator_api_names_v1Z_estimator_api_constants_v1Z_keras_api_names_v1Z_keras_api_constants_v1c@seZdZdZdS)SymbolAlreadyExposedErrorzBRaised when adding API names to symbol that already has API names.N)__name__ __module__ __qualname____doc__rrR/var/www/html/venv/lib/python3.7/site-packages/tensorflow/python/util/tf_export.pyr Tsr c@seZdZdZdS)InvalidSymbolNameErrorzDRaised when trying to export symbol as an invalid or unallowed name.N)r r r r rrrrrYsrcCs t|S)N)_NAME_TO_SYMBOL_MAPPINGget)namerrrget_symbol_from_name`srFc Cst|dsdSt|j}t|\}}||jkr4dSt||}|jdg}t||}|r^|St |j}t||}t||} |rd| S| S)aGet canonical name for the API symbol.

We need to ensure things exported by tf_export, estimator_export, etc. export symbols under disjoint top-level package names. For TensorFlow, we check that it does not export anything under subpackage names used by components (estimator, keras, etc.). For each component, we check that it exports everything under its own subpackage.
