# TODO(b/148678573,b/148685415): must use the ReferenceExecutor

[MazharAly]

While executing the code I am facing following error in the line 2;

Code:
"
......
tf.compat.v1.enable_v2_behavior()

"# TODO(b/148678573,b/148685415): must use the ReferenceExecutor because it
"# supports unbounded references and tff.sequence_* intrinsics.
tff.framework.set_default_executor(tff.framework.ReferenceExecutor())

"
Error:

----> [7] tff.framework.set_default_executor(tff.framework.ReferenceExecutor())

AttributeError: module 'tensorflow_federated.python.core.framework' has no attribute 'set_default_executor'

Please guide me in current situation as there are no "set_default_executor()" and "ReferenceExecutor()" functions in tff.framework class.
