If an object is a `CompositeTensor` and overrides its `_convert_variables_to_tensors` method, its `ResourceVariable` components will also be converted to `Tensor`s. Objects other than `ResourceVariable`s in `values` will be returned unchanged. Args: values: A nested structure of `ResourceVariable`s, or any other objects. Returns: A new structure with `ResourceVariable`s in `values` converted to `Tensor`s. ctj|rtj|St |t j rt j|S|S)N)rIsResourceVariablerconvert_to_tensor isinstancerCompositeTensorconvert_variables_to_tensorsxs U/home/dcms/DCMS/lib/python3.12/site-packages/tensorflow/python/util/variable_utils.py$_convert_resource_variable_to_tensorzJconvert_variables_to_tensors.._convert_resource_variable_to_tensor%sH''*  " "1 %% A'77 8  : :1 == hr map_structure)valuesrs rr r s   @& IIrc4d}tj||S)aReplaces `ResourceVariable`s in `values` with tf.nest atoms. This function is mostly for backward compatibility. Historically, `ResourceVariable`s are treated as tf.nest atoms. This is no longer the case after `ResourceVariable` becoming `CompositeTensor`. Unfortunately, tf.nest doesn't allow customization of what objects are treated as atoms. Calling this function to manually convert `ResourceVariable`s to atoms to avoid breaking tf.assert_same_structure with inputs of a `ResourceVariable` and an atom, like a `Tensor`. The specific implementation uses 0 as the tf.nest atom, but other tf.nest atoms could also serve the purpose. Note, the `TypeSpec` of None is not a tf.nest atom. Objects other than `ResourceVariable`s in `values` will be returned unchanged. Note: this function does not look into `CompositeTensor`s. Replacing `ResourceVariable`s in a `CompositeTensor` with atoms will change the `TypeSpec` of the `CompositeTensor`, which violates the semantics of `CompositeTensor` and tf.nest. So `ResourceVariable`s in `CompositeTensor`s will be returned as they are. Args: values: A nested structure of `ResourceVariable`s, or any other objects. Returns: A new structure with `ResourceVariable`s in `values` converted to atoms. c2tj|ry|S)Nr)rr rs r$_replace_resource_variable_with_atomzJreplace_variables_with_atoms.._replace_resource_variable_with_atomMs''*  hrr)rrs rreplace_variables_with_atomsr0s:   @& IIrN) __doc__tensorflow.python.frameworkrrtensorflow.python.utilrrr rrrrs"08+0'J2#Jr
