Applies tf.identity pointwise to source.
tff.utils.identity(
source
)
This utility function provides the exact same behavior as tf.identity, but
it generalizes to a wider class of objects, including ordinary tensors,
variables, as well as various types of nested structures. It would typically
be used together with tf.control_dependencies in non-eager TensorFlow.
Args |
|---|
source
|
A nested structure composed of tensors or variables embedded in
containers that are compatible with tf.nest, or instances of
structure.Struct. Elements that represent variables have
their content extracted prior to identity mapping by first invoking
tf.Variable.read_value.
|
Returns |
|---|
The result of applying tf.identity to read all elements of the source
pointwise, with the same structure as source.
|
Raises |
|---|
TypeError
|
If types mismatch.
